+// GTMSessionFetcher is a wrapper around NSURLSession for http operations.
+//
+// What does this offer on top of of NSURLSession?
+//
+// - Block-style callbacks for useful functionality like progress rather
+//   than delegate methods.
+// - Out-of-process uploads and downloads using NSURLSession, including
+//   management of fetches after relaunch.
+// - Integration with GTMAppAuth for invisible management and refresh of
+//   authorization tokens.
+// - Pretty-printed http logging.
+// - Cookies handling that does not interfere with or get interfered with
+//   by WebKit cookies or on Mac by Safari and other apps.
+// - Credentials handling for the http operation.
+// - Rate-limiting and cookie grouping when fetchers are created with
+//   GTMSessionFetcherService.
+//
+// If the bodyData or bodyFileURL property is set, then a POST request is assumed.
+//
+// Each fetcher is assumed to be for a one-shot fetch request; don't reuse the object
+// for a second fetch.
+//
+// The fetcher will be self-retained as long as a connection is pending.
+//
+// To keep user activity private, URLs must have an https scheme (unless the property
+// allowedInsecureSchemes is set to permit the scheme.)
+//
+// Callbacks will be released when the fetch completes or is stopped, so there is no need
+// to use weak self references in the callback blocks.
+//
+// Sample usage:
+//
+//  _fetcherService = [[GTMSessionFetcherService alloc] init];
+//
+//  GTMSessionFetcher *myFetcher = [_fetcherService fetcherWithURLString:myURLString];
+//  myFetcher.retryEnabled = YES;
+//  myFetcher.comment = @"First profile image";
+//
+//  // Optionally specify a file URL or NSData for the request body to upload.
+//  myFetcher.bodyData = [postString dataUsingEncoding:NSUTF8StringEncoding];
+//
+//  [myFetcher beginFetchWithCompletionHandler:^(NSData *data, NSError *error) {
+//    if (error != nil) {
+//      // Server status code or network error.
+//      //
+//      // If the domain is kGTMSessionFetcherStatusDomain then the error code
+//      // is a failure status from the server.
+//    } else {
+//      // Fetch succeeded.
+//    }
+//  }];
+//
+// There is also a beginFetch call that takes a pointer and selector for the completion handler;
+// a pointer and selector is a better style when the callback is a substantial, separate method.
+//
+// NOTE:  Fetches may retrieve data from the server even though the server
+//        returned an error, so the criteria for success is a non-nil error.
+//        The completion handler is called when the server status is >= 300 with an NSError
+//        having domain kGTMSessionFetcherStatusDomain and code set to the server status.
+//
+//        Status codes are at <http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html>
+//
+//
+// Background session support:
+//
+// Out-of-process uploads and downloads may be created by setting the fetcher's
+// useBackgroundSession property. Data to be uploaded should be provided via
+// the uploadFileURL property; the download destination should be specified with
+// the destinationFileURL.  NOTE: Background upload files should be in a location
+// that will be valid even after the device is restarted, so the file should not
+// be uploaded from a system temporary or cache directory.
+//
+// Background session transfers are slower, and should typically be used only
+// for very large downloads or uploads (hundreds of megabytes).
+//
+// When background sessions are used in iOS apps, the application delegate must
+// pass through the parameters from UIApplicationDelegate's
+// application:handleEventsForBackgroundURLSession:completionHandler: to the
+// fetcher class.
+//
+// When the application has been relaunched, it may also create a new fetcher
+// instance to handle completion of the transfers.
+//
+//  - (void)application:(UIApplication *)application
+//      handleEventsForBackgroundURLSession:(NSString *)identifier
+//                        completionHandler:(void (^)())completionHandler {
+//    // Application was re-launched on completing an out-of-process download.
+//
+//    // Pass the URLSession info related to this re-launch to the fetcher class.
+//    [GTMSessionFetcher application:application
+//        handleEventsForBackgroundURLSession:identifier
+//                          completionHandler:completionHandler];
+//
+//    // Get a fetcher related to this re-launch and re-hook up a completionHandler to it.
+//    GTMSessionFetcher *fetcher = [GTMSessionFetcher fetcherWithSessionIdentifier:identifier];
+//    NSURL *destinationFileURL = fetcher.destinationFileURL;
+//    fetcher.completionHandler = ^(NSData *data, NSError *error) {
+//      [self downloadCompletedToFile:destinationFileURL error:error];
+//    };
+//  }
+//
+//
+// Threading and queue support:
+//
+// Networking always happens on a background thread; there is no advantage to
+// changing thread or queue to create or start a fetcher.
+//
+// Callbacks are run on the main thread; alternatively, the app may set the
+// fetcher's callbackQueue to a dispatch queue.
+//
+// Once the fetcher's beginFetch method has been called, the fetcher's methods and
+// properties may be accessed from any thread.
+//
+// Downloading to disk:
+//
+// To have downloaded data saved directly to disk, specify a file URL for the
+// destinationFileURL property.
+//
+// HTTP methods and headers:
+//
+// Alternative HTTP methods, like PUT, and custom headers can be specified by
+// creating the fetcher with an appropriate NSMutableURLRequest.
+//
+//
+// Caching:
+//
+// The fetcher avoids caching. That is best for API requests, but may hurt
+// repeat fetches of static data. Apps may enable a persistent disk cache by
+// customizing the config:
+//
+//  fetcher.configurationBlock = ^(GTMSessionFetcher *configFetcher,
+//                                 NSURLSessionConfiguration *config) {
+//    config.URLCache = [NSURLCache sharedURLCache];
+//  };
+//
+// Or use the standard system config to share cookie storage with web views
+// and to enable disk caching:
+//
+//  fetcher.configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+//
+//
+// Cookies:
+//
+// There are three supported mechanisms for remembering cookies between fetches.
+//
+// By default, a standalone GTMSessionFetcher uses a mutable array held
+// statically to track cookies for all instantiated fetchers.  This avoids
+// cookies being set by servers for the application from interfering with
+// Safari and WebKit cookie settings, and vice versa.
+// The fetcher cookies are lost when the application quits.
+//
+// To rely instead on WebKit's global NSHTTPCookieStorage, set the fetcher's
+// cookieStorage property:
+//   myFetcher.cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
+//
+// To share cookies with other apps, use the method introduced in iOS 9/OS X 10.11:
+//   myFetcher.cookieStorage =
+//     [NSHTTPCookieStorage sharedCookieStorageForGroupContainerIdentifier:kMyCompanyContainedID];
+//
+// To ignore existing cookies and only have cookies related to the single fetch
+// be applied, make a temporary cookie storage object:
+//   myFetcher.cookieStorage = [[GTMSessionCookieStorage alloc] init];
+//
+// Note: cookies set while following redirects will be sent to the server, as
+// the redirects are followed by the fetcher.
+//
+// To completely disable cookies, similar to setting cookieStorageMethod to
+// kGTMHTTPFetcherCookieStorageMethodNone, adjust the session configuration
+// appropriately in the fetcher or fetcher service:
+//  fetcher.configurationBlock = ^(GTMSessionFetcher *configFetcher,
+//                                 NSURLSessionConfiguration *config) {
+//    config.HTTPCookieAcceptPolicy = NSHTTPCookieAcceptPolicyNever;
+//    config.HTTPShouldSetCookies = NO;
+//  };
+//
+// If the fetcher is created from a GTMSessionFetcherService object
+// then the cookie storage mechanism is set to use the cookie storage in the
+// service object rather than the static storage. Disabling cookies in the

+// Monitoring data transfers.

+// progress with callback blocks.
+//  GTMSessionFetcherSendProgressBlock sendProgressBlock
+//  GTMSessionFetcherReceivedProgressBlock receivedProgressBlock
+//  GTMSessionFetcherDownloadProgressBlock downloadProgressBlock
+//
+// If supplied by the server, the anticipated total download size is available
+// as [[myFetcher response] expectedContentLength] (and may be -1 for unknown
+// download sizes.)
+//
+//
+// Automatic retrying of fetches
+//
+// The fetcher can optionally create a timer and reattempt certain kinds of
+// fetch failures (status codes 408, request timeout; 502, gateway failure;
+// 503, service unavailable; 504, gateway timeout; networking errors
+// NSURLErrorTimedOut and NSURLErrorNetworkConnectionLost.)  The user may
+// set a retry selector to customize the type of errors which will be retried.
+//
+// Retries are done in an exponential-backoff fashion (that is, after 1 second,
+// 2, 4, 8, and so on.)
+//
+// Enabling automatic retries looks like this:
+//  myFetcher.retryEnabled = YES;
+//
+// With retries enabled, the completion callbacks are called only
+// when no more retries will be attempted. Calling the fetcher's stopFetching
+// method will terminate the retry timer, without the finished or failure
+// selectors being invoked.
+//
+// Optionally, the client may set the maximum retry interval:
+//  myFetcher.maxRetryInterval = 60.0; // in seconds; default is 60 seconds
+//                                     // for downloads, 600 for uploads
+//
+// Servers should never send a 400 or 500 status for errors that are retryable
+// by clients, as those values indicate permanent failures. In nearly all
+// cases, the default standard retry behavior is correct for clients, and no
+// custom client retry behavior is needed or appropriate. Servers that send
+// non-retryable status codes and expect the client to retry the request are
+// faulty.
+//
+// Still, the client may provide a block to determine if a status code or other
+// error should be retried. The block returns YES to set the retry timer or NO
+// to fail without additional fetch attempts.
+//
+// The retry method may return the |suggestedWillRetry| argument to get the
+// default retry behavior.  Server status codes are present in the
+// error argument, and have the domain kGTMSessionFetcherStatusDomain. The
+// user's method may look something like this:
+//
+//  myFetcher.retryBlock = ^(BOOL suggestedWillRetry, NSError *error,
+//                           GTMSessionFetcherRetryResponse response) {
+//    // Perhaps examine error.domain and error.code, or fetcher.retryCount
+//    //
+//    // Respond with YES to start the retry timer, NO to proceed to the failure
+//    // callback, or suggestedWillRetry to get default behavior for the
+//    // current error domain and code values.

+ *  `ProductSet` or `Product` for the image. In this case, the
+ *  `product-display-name` column refers to
+ *  display_name, the
+ *  `product-category` column refers to
+ *  product_category, and the
+ *  `labels` column refers to product_labels.
+ *  The `image-id` column is optional but must be unique if provided. If it is
+ *  empty, the system will automatically assign a unique id to the image.
+ *  The `product-display-name` column is optional. If it is empty, the system
+ *  sets the display_name field for the product to a
+ *  space (" "). You can update the `display_name` later by using the API.
+ *  If a `Product` with the specified `product-id` already exists, then the
+ *  system ignores the `product-display-name`, `product-category`, and `labels`
+ *  columns.
+ *  The `labels` column (optional) is a line containing a list of
+ *  comma-separated key-value pairs, in the following format:
+ *  "key_1=value_1,key_2=value_2,...,key_n=value_n"
+ *  The `bounding-poly` column (optional) identifies one region of
+ *  interest from the image in the same manner as `CreateReferenceImage`. If
+ *  you do not specify the `bounding-poly` column, then the system will try to
+ *  detect regions of interest automatically.
+ *  At most one `bounding-poly` column is allowed per line. If the image
+ *  contains multiple regions of interest, add a line to the CSV file that
+ *  includes the same product information, and the `bounding-poly` values for
+ *  each region of interest.
+ *  The `bounding-poly` column must contain an even number of comma-separated
+ *  numbers, in the format "p1_x,p1_y,p2_x,p2_y,...,pn_x,pn_y". Use
+ *  non-negative integers for absolute bounding polygons, and float values
+ *  in [0, 1] for normalized bounding polygons.
+ *  The system will resize the image if the image resolution is too
+ *  large to process (larger than 20MP).

+/**
+ *  The `Status` type defines a logical error model that is suitable for
+ *  different
+ *  programming environments, including REST APIs and RPC APIs. It is used by
+ *  [gRPC](https://github.com/grpc). The error model is designed to be:
+ *  - Simple to use and understand for most users
+ *  - Flexible enough to meet unexpected needs
+ *  # Overview
+ *  The `Status` message contains three pieces of data: error code, error
+ *  message,
+ *  and error details. The error code should be an enum value of
+ *  google.rpc.Code, but it may accept additional error codes if needed. The
+ *  error message should be a developer-facing English message that helps
+ *  developers *understand* and *resolve* the error. If a localized user-facing
+ *  error message is needed, put the localized message in the error details or
+ *  localize it in the client. The optional error details may contain arbitrary
+ *  information about the error. There is a predefined set of error detail types
+ *  in the package `google.rpc` that can be used for common error conditions.
+ *  # Language mapping
+ *  The `Status` message is the logical representation of the error model, but
+ *  it
+ *  is not necessarily the actual wire format. When the `Status` message is
+ *  exposed in different client libraries and different wire protocols, it can
+ *  be
+ *  mapped differently. For example, it will likely be mapped to some exceptions
+ *  in Java, but more likely mapped to some error codes in C.
+ *  # Other uses
+ *  The error model and the `Status` message can be used in a variety of
+ *  environments, either with or without APIs, to provide a
+ *  consistent developer experience across different environments.
+ *  Example uses of this error model include:
+ *  - Partial errors. If a service needs to return partial errors to the client,
+ *  it may embed the `Status` in the normal response to indicate the partial
+ *  errors.
+ *  - Workflow errors. A typical workflow has multiple steps. Each step may
+ *  have a `Status` message for error reporting.
+ *  - Batch operations. If a client uses batch request and batch response, the
+ *  `Status` message should be used directly inside batch response, one for
+ *  each error sub-response.
+ *  - Asynchronous operations. If an API call embeds asynchronous operation
+ *  results in its response, the status of those operations should be
+ *  represented directly using the `Status` message.
+ *  - Logging. If some API errors are stored in logs, the message `Status` could
+ *  be used directly after any stripping needed for security/privacy reasons.

+//
+
+// Key Abstractions
+// ----------------
+//
+// This file declares multiple classes and protocols that are used by the
+// GTMLogger logging system. The 4 main abstractions used in this file are the
+// following:
+//
+//   * logger (GTMLogger) - The main logging class that users interact with. It
+//   has methods for logging at different levels and uses a log writer, a log
+//   formatter, and a log filter to get the job done.
+//
+//   * log writer (GTMLogWriter) - Writes a given string to some log file, where
+//   a "log file" can be a physical file on disk, a POST over HTTP to some URL,
+//   or even some in-memory structure (e.g., a ring buffer).
+//
+//   * log formatter (GTMLogFormatter) - Given a format string and arguments as
+//   a va_list, returns a single formatted NSString. A "formatted string" could
+//   be a string with the date prepended, a string with values in a CSV format,
+//   or even a string of XML.
+//
+//   * log filter (GTMLogFilter) - Given a formatted log message as an NSString
+//   and the level at which the message is to be logged, this class will decide
+//   whether the given message should be logged or not. This is a flexible way
+//   to filter out messages logged at a certain level, messages that contain
+//   certain text, or filter nothing out at all. This gives the caller the
+//   flexibility to dynamically enable debug logging in Release builds.
+//
+// This file also declares some classes to handle the common log writer, log
+// formatter, and log filter cases. Callers can also create their own writers,
+// formatters, and filters and they can even build them on top of the ones
+// declared here. Keep in mind that your custom writer/formatter/filter may be
+// called from multiple threads, so it must be thread-safe.
+
+#import <Foundation/Foundation.h>
+#import "GTMDefines.h"
+
+// Predeclaration of used protocols that are declared later in this file.
+@protocol GTMLogWriter, GTMLogFormatter, GTMLogFilter;
+
+// GTMLogger
+//
+// GTMLogger is the primary user-facing class for an object-oriented logging
+// system. It is built on the concept of log formatters (GTMLogFormatter), log
+// writers (GTMLogWriter), and log filters (GTMLogFilter). When a message is
+// sent to a GTMLogger to log a message, the message is formatted using the log
+// formatter, then the log filter is consulted to see if the message should be
+// logged, and if so, the message is sent to the log writer to be written out.
+//
+// GTMLogger is intended to be a flexible and thread-safe logging solution. Its
+// flexibility comes from the fact that GTMLogger instances can be customized
+// with user defined formatters, filters, and writers. And these writers,
+// filters, and formatters can be combined, stacked, and customized in arbitrary
+// ways to suit the needs at hand. For example, multiple writers can be used at
+// the same time, and a GTMLogger instance can even be used as another
+// GTMLogger's writer. This allows for arbitrarily deep logging trees.
+//
+// A standard GTMLogger uses a writer that sends messages to standard out, a
+// formatter that smacks a timestamp and a few other bits of interesting
+// information on the message, and a filter that filters out debug messages from
+// release builds. Using the standard log settings, a log message will look like
+// the following:
+//
+//   2007-12-30 10:29:24.177 myapp[4588/0xa07d0f60] [lvl=1] foo=<Foo: 0x123>
+//
+// The output contains the date and time of the log message, the name of the
+// process followed by its process ID/thread ID, the log level at which the
+// message was logged (in the previous example the level was 1:
+// kGTMLoggerLevelDebug), and finally, the user-specified log message itself (in
+// this case, the log message was @"foo=%@", foo).
+//
+// Multiple instances of GTMLogger can be created, each configured their own
+// way.  Though GTMLogger is not a singleton (in the GoF sense), it does provide
+// access to a shared (i.e., globally accessible) GTMLogger instance. This makes
+// it convenient for all code in a process to use the same GTMLogger instance.
+// The shared GTMLogger instance can also be configured in an arbitrary, and
+// these configuration changes will affect all code that logs through the shared
+// instance.
+
+//
+// Log Levels
+// ----------
+// GTMLogger has 3 different log levels: Debug, Info, and Error. GTMLogger
+// doesn't take any special action based on the log level; it simply forwards
+// this information on to formatters, filters, and writers, each of which may
+// optionally take action based on the level. Since log level filtering is
+// performed at runtime, log messages are typically not filtered out at compile
+// time.  The exception to this rule is that calls to the GTMLoggerDebug() macro
+// *ARE* filtered out of non-DEBUG builds. This is to be backwards compatible
+// with behavior that many developers are currently used to. Note that this
+// means that GTMLoggerDebug(@"hi") will be compiled out of Release builds, but
+// [[GTMLogger sharedLogger] logDebug:@"hi"] will NOT be compiled out.
+//
+// Standard loggers are created with the GTMLogLevelFilter log filter, which
+// filters out certain log messages based on log level, and some other settings.
+//
+// In addition to the -logDebug:, -logInfo:, and -logError: methods defined on
+// GTMLogger itself, there are also C macros that make usage of the shared
+// GTMLogger instance very convenient. These macros are:
+//
+//   GTMLoggerDebug(...)
+//   GTMLoggerInfo(...)
+//   GTMLoggerError(...)
+//
+// Again, a notable feature of these macros is that GTMLogDebug() calls *will be
+// compiled out of non-DEBUG builds*.
+//
+// Standard Loggers
+// ----------------
+// GTMLogger has the concept of "standard loggers". A standard logger is simply
+// a logger that is pre-configured with some standard/common writer, formatter,
+// and filter combination. Standard loggers are created using the creation
+// methods beginning with "standard". The alternative to a standard logger is a
+// regular logger, which will send messages to stdout, with no special
+// formatting, and no filtering.
+//
+// How do I use GTMLogger?
+// ----------------------
+// The typical way you will want to use GTMLogger is to simply use the
+// GTMLogger*() macros for logging from code. That way we can easily make
+// changes to the GTMLogger class and simply update the macros accordingly. Only
+// your application startup code (perhaps, somewhere in main()) should use the
+// GTMLogger class directly in order to configure the shared logger, which all
+// of the code using the macros will be using. Again, this is just the typical
+// situation.
+//
+// To be complete, there are cases where you may want to use GTMLogger directly,
+// or even create separate GTMLogger instances for some reason. That's fine,
+// too.
+//
+// Examples
+// --------
+// The following show some common GTMLogger use cases.
+//
+// 1. You want to log something as simply as possible. Also, this call will only
+//    appear in debug builds. In non-DEBUG builds it will be completely removed.
+//
+//      GTMLoggerDebug(@"foo = %@", foo);
+//
+// 2. The previous example is similar to the following. The major difference is
+//    that the previous call (example 1) will be compiled out of Release builds
+//    but this statement will not be compiled out.
+//
+//      [[GTMLogger sharedLogger] logDebug:@"foo = %@", foo];
+//
+// 3. Send all logging output from the shared logger to a file. We do this by
+//    creating an NSFileHandle for writing associated with a file, and setting
+//    that file handle as the logger's writer.
+//
+//      NSFileHandle *f = [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log"
+//                                                          create:YES];
+//      [[GTMLogger sharedLogger] setWriter:f];
+//      GTMLoggerError(@"hi");  // This will be sent to /tmp/f.log
+//
+// 4. Create a new GTMLogger that will log to a file. This example differs from
+//    the previous one because here we create a new GTMLogger that is different
+//    from the shared logger.
+//
+//      GTMLogger *logger = [GTMLogger standardLoggerWithPath:@"/tmp/temp.log"];
+//      [logger logInfo:@"hi temp log file"];
+//
+// 5. Create a logger that writes to stdout and does NOT do any formatting to
+//    the log message. This might be useful, for example, when writing a help
+//    screen for a command-line tool to standard output.
+//
+//      GTMLogger *logger = [GTMLogger logger];
+//      [logger logInfo:@"%@ version 0.1 usage", progName];
+//
+// 6. Send log output to stdout AND to a log file. The trick here is that
+//    NSArrays function as composite log writers, which means when an array is
+//    set as the log writer, it forwards all logging messages to all of its
+//    contained GTMLogWriters.
+//
+//      // Create array of GTMLogWriters
+//      NSArray *writers = [NSArray arrayWithObjects:
+//          [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" create:YES],
+//          [NSFileHandle fileHandleWithStandardOutput], nil];
+//
+//      GTMLogger *logger = [GTMLogger standardLogger];
+//      [logger setWriter:writers];
+//      [logger logInfo:@"hi"];  // Output goes to stdout and /tmp/f.log
+//
+// For futher details on log writers, formatters, and filters, see the
+// documentation below.
+//
+// NOTE: GTMLogger is application level logging.  By default it does nothing
+// with _GTMDevLog/_GTMDevAssert (see GTMDefines.h).  An application can choose
+// to bridge _GTMDevLog/_GTMDevAssert to GTMLogger by providing macro
+// definitions in its prefix header (see GTMDefines.h for how one would do
+// that).

+ * `Any` contains an arbitrary serialized protocol buffer message along with a
+ * URL that describes the type of the serialized message.
+ *
+ * Protobuf library provides support to pack/unpack Any values in the form
+ * of utility functions or additional generated methods of the Any type.
+ *
+ * Example 1: Pack and unpack a message in C++.
+ *
+ *     Foo foo = ...;
+ *     Any any;
+ *     any.PackFrom(foo);
+ *     ...
+ *     if (any.UnpackTo(&foo)) {
+ *       ...
+ *     }
+ *
+ * Example 2: Pack and unpack a message in Java.
+ *
+ *     Foo foo = ...;
+ *     Any any = Any.pack(foo);
+ *     ...
+ *     if (any.is(Foo.class)) {
+ *       foo = any.unpack(Foo.class);
+ *     }
+ *
+ *  Example 3: Pack and unpack a message in Python.
+ *
+ *     foo = Foo(...)
+ *     any = Any()
+ *     any.Pack(foo)
+ *     ...
+ *     if any.Is(Foo.DESCRIPTOR):
+ *       any.Unpack(foo)
+ *       ...
+ *
+ *  Example 4: Pack and unpack a message in Go
+ *
+ *      foo := &pb.Foo{...}
+ *      any, err := ptypes.MarshalAny(foo)
+ *      ...
+ *      foo := &pb.Foo{}
+ *      if err := ptypes.UnmarshalAny(any, foo); err != nil {
+ *        ...
+ *      }
+ *
+ * The pack methods provided by protobuf library will by default use
+ * 'type.googleapis.com/full.type.name' as the type URL and the unpack
+ * methods only use the fully qualified type name after the last '/'
+ * in the type URL, for example "foo.bar.com/x/y.z" will yield type
+ * name "y.z".
+ *
+ *
+ * JSON
+ * ====
+ * The JSON representation of an `Any` value uses the regular
+ * representation of the deserialized, embedded message, with an
+ * additional field `\@type` which contains the type URL. Example:
+ *
+ *     package google.profile;
+ *     message Person {
+ *       string first_name = 1;
+ *       string last_name = 2;
+ *     }
+ *
+ *     {
+ *       "\@type": "type.googleapis.com/google.profile.Person",
+ *       "firstName": <string>,
+ *       "lastName": <string>
+ *     }
+ *
+ * If the embedded message type is well-known and has a custom JSON
+ * representation, that representation will be embedded adding a field
+ * `value` which holds the custom JSON in addition to the `\@type`
+ * field. Example (for message [google.protobuf.Duration][]):
+ *
+ *     {
+ *       "\@type": "type.googleapis.com/google.protobuf.Duration",
+ *       "value": "1.212s"
+ *     }
+ **/
+@interface GPBAny : GPBMessage
+
+/**
+ * A URL/resource name that uniquely identifies the type of the serialized
+ * protocol buffer message. This string must contain at least
+ * one "/" character. The last segment of the URL's path must represent
+ * the fully qualified name of the type (as in
+ * `path/google.protobuf.Duration`). The name should be in a canonical form
+ * (e.g., leading "." is not accepted).
+ *
+ * In practice, teams usually precompile into the binary all types that they
+ * expect it to use in the context of Any. However, for URLs which use the
+ * scheme `http`, `https`, or no scheme, one can optionally set up a type
+ * server that maps type URLs to message definitions as follows:
+ *
+ * * If no scheme is provided, `https` is assumed.
+ * * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+ *   value in binary format, or produce an error.
+ * * Applications are allowed to cache lookup results based on the
+ *   URL, or have them precompiled into a binary to avoid any
+ *   lookup. Therefore, binary compatibility needs to be preserved
+ *   on changes to types. (Use versioned type names to manage
+ *   breaking changes.)
+ *
+ * Note: this functionality is not currently available in the official
+ * protobuf release, and it is not used for type URLs beginning with
+ * type.googleapis.com.
+ *
+ * Schemes other than `http`, `https` (or the empty scheme) might be
+ * used with implementation specific semantics.

+ *       - name: google.acl.v1.AccessControl
+ *
+ * The mixin construct implies that all methods in `AccessControl` are
+ * also declared with same name and request/response types in
+ * `Storage`. A documentation generator or annotation processor will
+ * see the effective `Storage.GetAcl` method after inherting
+ * documentation and annotations as follows:
+ *
+ *     service Storage {
+ *       // Get the underlying ACL object.
+ *       rpc GetAcl(GetAclRequest) returns (Acl) {
+ *         option (google.api.http).get = "/v2/{resource=**}:getAcl";
+ *       }
+ *       ...
+ *     }
+ *
+ * Note how the version in the path pattern changed from `v1` to `v2`.
+ *
+ * If the `root` field in the mixin is specified, it should be a
+ * relative path under which inherited HTTP paths are placed. Example:
+ *
+ *     apis:
+ *     - name: google.storage.v2.Storage
+ *       mixins:
+ *       - name: google.acl.v1.AccessControl
+ *         root: acls
+ *
+ * This implies the following inherited HTTP annotation:
+ *
+ *     service Storage {
+ *       // Get the underlying ACL object.
+ *       rpc GetAcl(GetAclRequest) returns (Acl) {
+ *         option (google.api.http).get = "/v2/acls/{resource=**}:getAcl";
+ *       }

+/**
+ * A Duration represents a signed, fixed-length span of time represented
+ * as a count of seconds and fractions of seconds at nanosecond
+ * resolution. It is independent of any calendar and concepts like "day"
+ * or "month". It is related to Timestamp in that the difference between
+ * two Timestamp values is a Duration and it can be added or subtracted
+ * from a Timestamp. Range is approximately +-10,000 years.
+ *
+ * # Examples
+ *
+ * Example 1: Compute Duration from two Timestamps in pseudo code.
+ *
+ *     Timestamp start = ...;
+ *     Timestamp end = ...;
+ *     Duration duration = ...;
+ *
+ *     duration.seconds = end.seconds - start.seconds;
+ *     duration.nanos = end.nanos - start.nanos;
+ *
+ *     if (duration.seconds < 0 && duration.nanos > 0) {
+ *       duration.seconds += 1;
+ *       duration.nanos -= 1000000000;
+ *     } else if (durations.seconds > 0 && duration.nanos < 0) {
+ *       duration.seconds -= 1;
+ *       duration.nanos += 1000000000;
+ *     }
+ *
+ * Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
+ *
+ *     Timestamp start = ...;
+ *     Duration duration = ...;
+ *     Timestamp end = ...;
+ *
+ *     end.seconds = start.seconds + duration.seconds;
+ *     end.nanos = start.nanos + duration.nanos;
+ *
+ *     if (end.nanos < 0) {
+ *       end.seconds -= 1;
+ *       end.nanos += 1000000000;
+ *     } else if (end.nanos >= 1000000000) {
+ *       end.seconds += 1;
+ *       end.nanos -= 1000000000;
+ *     }
+ *
+ * Example 3: Compute Duration from datetime.timedelta in Python.
+ *
+ *     td = datetime.timedelta(days=3, minutes=10)
+ *     duration = Duration()
+ *     duration.FromTimedelta(td)
+ *
+ * # JSON Mapping
+ *
+ * In JSON format, the Duration type is encoded as a string rather than an
+ * object, where the string ends in the suffix "s" (indicating seconds) and
+ * is preceded by the number of seconds, with nanoseconds expressed as
+ * fractional seconds. For example, 3 seconds with 0 nanoseconds should be
+ * encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
+ * be expressed in JSON format as "3.000000001s", and 3 seconds and 1

+ * `FieldMask` represents a set of symbolic field paths, for example:
+ *
+ *     paths: "f.a"
+ *     paths: "f.b.d"
+ *
+ * Here `f` represents a field in some root message, `a` and `b`
+ * fields in the message found in `f`, and `d` a field found in the
+ * message in `f.b`.
+ *
+ * Field masks are used to specify a subset of fields that should be
+ * returned by a get operation or modified by an update operation.
+ * Field masks also have a custom JSON encoding (see below).
+ *
+ * # Field Masks in Projections
+ *
+ * When used in the context of a projection, a response message or
+ * sub-message is filtered by the API to only contain those fields as
+ * specified in the mask. For example, if the mask in the previous
+ * example is applied to a response message as follows:
+ *
+ *     f {
+ *       a : 22
+ *       b {
+ *         d : 1
+ *         x : 2
+ *       }
+ *       y : 13
+ *     }
+ *     z: 8
+ *
+ * The result will not contain specific values for fields x,y and z
+ * (their value will be set to the default, and omitted in proto text
+ * output):
+ *
+ *
+ *     f {
+ *       a : 22
+ *       b {
+ *         d : 1
+ *       }
+ *     }
+ *
+ * A repeated field is not allowed except at the last position of a
+ * paths string.
+ *
+ * If a FieldMask object is not present in a get operation, the
+ * operation applies to all fields (as if a FieldMask of all fields
+ * had been specified).
+ *
+ * Note that a field mask does not necessarily apply to the
+ * top-level response message. In case of a REST get operation, the
+ * field mask applies directly to the response, but in case of a REST
+ * list operation, the mask instead applies to each individual message
+ * in the returned resource list. In case of a REST custom method,
+ * other definitions may be used. Where the mask applies will be
+ * clearly documented together with its declaration in the API.  In
+ * any case, the effect on the returned resource/resources is required
+ * behavior for APIs.
+ *
+ * # Field Masks in Update Operations
+ *
+ * A field mask in update operations specifies which fields of the
+ * targeted resource are going to be updated. The API is required
+ * to only change the values of the fields as specified in the mask
+ * and leave the others untouched. If a resource is passed in to
+ * describe the updated values, the API ignores the values of all
+ * fields not covered by the mask.
+ *
+ * If a repeated field is specified for an update operation, new values will
+ * be appended to the existing repeated field in the target resource. Note that
+ * a repeated field is only allowed in the last position of a `paths` string.
+ *
+ * If a sub-message is specified in the last position of the field mask for an
+ * update operation, then new value will be merged into the existing sub-message
+ * in the target resource.
+ *
+ * For example, given the target message:
+ *
+ *     f {
+ *       b {
+ *         d: 1
+ *         x: 2
+ *       }
+ *       c: [1]
+ *     }
+ *
+ * And an update message:
+ *
+ *     f {
+ *       b {
+ *         d: 10
+ *       }
+ *       c: [2]
+ *     }
+ *
+ * then if the field mask is:
+ *
+ *  paths: ["f.b", "f.c"]
+ *
+ * then the result will be:
+ *
+ *     f {
+ *       b {
+ *         d: 10
+ *         x: 2
+ *       }
+ *       c: [1, 2]
+ *     }
+ *
+ * An implementation may provide options to override this default behavior for
+ * repeated and message fields.
+ *
+ * In order to reset a field's value to the default, the field must
+ * be in the mask and set to the default value in the provided resource.
+ * Hence, in order to reset all fields of a resource, provide a default
+ * instance of the resource and set all fields in the mask, or do
+ * not provide a mask as described below.
+ *
+ * If a field mask is not present on update, the operation applies to
+ * all fields (as if a field mask of all fields has been specified).
+ * Note that in the presence of schema evolution, this may mean that
+ * fields the client does not know and has therefore not filled into
+ * the request will be reset to their default. If this is unwanted
+ * behavior, a specific service may require a client to always specify
+ * a field mask, producing an error if not.
+ *
+ * As with get operations, the location of the resource which
+ * describes the updated values in the request message depends on the
+ * operation kind. In any case, the effect of the field mask is
+ * required to be honored by the API.
+ *
+ * ## Considerations for HTTP REST
+ *
+ * The HTTP kind of an update operation which uses a field mask must
+ * be set to PATCH instead of PUT in order to satisfy HTTP semantics
+ * (PUT must only be used for full updates).
+ *
+ * # JSON Encoding of Field Masks
+ *
+ * In JSON, a field mask is encoded as a single string where paths are
+ * separated by a comma. Fields name in each path are converted
+ * to/from lower-camel naming conventions.
+ *
+ * As an example, consider the following message declarations:
+ *
+ *     message Profile {
+ *       User user = 1;
+ *       Photo photo = 2;
+ *     }
+ *     message User {
+ *       string display_name = 1;
+ *       string address = 2;
+ *     }
+ *
+ * In proto a field mask for `Profile` may look as such:
+ *
+ *     mask {
+ *       paths: "user.display_name"
+ *       paths: "photo"
+ *     }
+ *
+ * In JSON, the same mask is represented as below:
+ *
+ *     {
+ *       mask: "user.displayName,photo"
+ *     }
+ *
+ * # Field Masks and Oneof Fields
+ *
+ * Field masks treat fields in oneofs just as regular fields. Consider the
+ * following message:
+ *
+ *     message SampleMessage {
+ *       oneof test_oneof {
+ *         string name = 4;
+ *         SubMessage sub_message = 9;
+ *       }
+ *     }
+ *
+ * The field mask can be:
+ *
+ *     mask {
+ *       paths: "name"
+ *     }
+ *
+ * Or:
+ *
+ *     mask {
+ *       paths: "sub_message"
+ *     }
+ *
+ * Note that oneof type names ("test_oneof" in this case) cannot be used in
+ * paths.
+ *
+ * ## Field Mask Verification
+ *
+ * The implementation of any API method which has a FieldMask type field in the
+ * request should verify the included field paths, and return an
+ * `INVALID_ARGUMENT` error if any path is duplicated or unmappable.

+/**
+ * A Timestamp represents a point in time independent of any time zone or local
+ * calendar, encoded as a count of seconds and fractions of seconds at
+ * nanosecond resolution. The count is relative to an epoch at UTC midnight on
+ * January 1, 1970, in the proleptic Gregorian calendar which extends the
+ * Gregorian calendar backwards to year one.
+ *
+ * All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+ * second table is needed for interpretation, using a [24-hour linear
+ * smear](https://developers.google.com/time/smear).
+ *
+ * The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+ * restricting to that range, we ensure that we can convert to and from [RFC
+ * 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+ *
+ * # Examples
+ *
+ * Example 1: Compute Timestamp from POSIX `time()`.
+ *
+ *     Timestamp timestamp;
+ *     timestamp.set_seconds(time(NULL));
+ *     timestamp.set_nanos(0);
+ *
+ * Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+ *
+ *     struct timeval tv;
+ *     gettimeofday(&tv, NULL);
+ *
+ *     Timestamp timestamp;
+ *     timestamp.set_seconds(tv.tv_sec);
+ *     timestamp.set_nanos(tv.tv_usec * 1000);
+ *
+ * Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+ *
+ *     FILETIME ft;
+ *     GetSystemTimeAsFileTime(&ft);
+ *     UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+ *
+ *     // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+ *     // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+ *     Timestamp timestamp;
+ *     timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+ *     timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+ *
+ * Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+ *
+ *     long millis = System.currentTimeMillis();
+ *
+ *     Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+ *         .setNanos((int) ((millis % 1000) * 1000000)).build();
+ *
+ *
+ * Example 5: Compute Timestamp from current time in Python.
+ *
+ *     timestamp = Timestamp()
+ *     timestamp.GetCurrentTime()
+ *
+ * # JSON Mapping
+ *
+ * In JSON format, the Timestamp type is encoded as a string in the
+ * [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+ * format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+ * where {year} is always expressed using four digits while {month}, {day},
+ * {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+ * seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+ * are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+ * is required. A proto3 JSON serializer should always use UTC (as indicated by
+ * "Z") when printing the Timestamp type and a proto3 JSON parser should be
+ * able to accept both UTC and other timezones (as indicated by an offset).
+ *
+ * For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+ * 01:30 UTC on January 15, 2017.
+ *
+ * In JavaScript, one can convert a Date object to this format using the
+ * standard [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+ * method. In Python, a standard `datetime.datetime` object can be converted
+ * to this format using [`strftime`](https://docs.python.org/2/library/time.html#time.strftime)
+ * with the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one
+ * can use the Joda Time's [`ISODateTimeFormat.dateTime()`](
+ * http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
+ * ) to obtain a formatter capable of generating timestamps in this format.
