The reason for this is to keep the amount of memory that is - allocated, but not yet freed because it is dependent on the autorelease pool to pop before it can be reclaimed. - - In the simpler v1.3 code, this included all the bytes used to store the -UTF8String along with the JSONDecoder and all its overhead. - - Now we use an autoreleased CFMutableData that is sized to the UTF8 length of the NSString in question and is used to hold the UTF8 - conversion of said string. - - Once parsed, the CFMutableData has its length set to 0. This should, hopefully, allow the CFMutableData to realloc and/or free - the buffer. - - Another change made was a slight modification to JSONDecoder so that most of the cleanup work that was done in -dealloc was moved - to a private, internal function. These convenience routines keep the pointer to the autoreleased JSONDecoder and calls - _JSONDecoderCleanup() to early release the decoders resources since we already know that particular decoder is not going to be used - again. - - If everything goes smoothly, this will most likely result in perhaps a few hundred bytes that are allocated but waiting for the - autorelease pool to pop. This is compared to the thousands and easily hundreds of thousands of bytes that would have been in - autorelease limbo. It's more complicated for us, but a win for the user. - - Autorelease objects are used in case things don't go smoothly. By having them autoreleased, we effectively guarantee that our - requirement to -release the object is always met, not matter what goes wrong. The downside is having a an object or two in - autorelease limbo, but we've done our best to minimize that impact, so it all balances out. - */ - -@implementation NSString (JSONKitDeserializing) - -static id _NSStringObjectFromJSONString(NSString *jsonString, JKParseOptionFlags parseOptionFlags, NSError **error, BOOL mutableCollection) { - id returnObject = NULL;
