 /**
  * The **Archive** class is used to query cached analytics statistics
  * (termed "archive data").
- * 
+ *
  * You can use **Archive** instances to get data that was archived for one or more sites,
  * for one or more periods and one optional segment.
- * 
+ *
  * If archive data is not found, this class will initiate the archiving process. [1](#footnote-1)
- * 
+ *
  * **Archive** instances must be created using the {@link build()} factory method;
  * they cannot be constructed.
- * 
+ *
  * You can search for metrics (such as `nb_visits`) using the {@link getNumeric()} and
  * {@link getDataTableFromNumeric()} methods. You can search for
  * reports using the {@link getBlob()}, {@link getDataTable()} and {@link getDataTableExpanded()} methods.
- * 
+ *
  * If you're creating an API that returns report data, you may want to use the
  * {@link getDataTableFromArchive()} helper function.
- * 
+ *
  * ### Learn more
- * 
+ *
  * Learn more about _archiving_ [here](/guides/all-about-analytics-data).
- * 
+ *
  * ### Limitations
- * 
+ *
  * - You cannot get data for multiple range periods in a single query.
  * - You cannot get data for periods of different types in a single query.
- * 
+ *
  * ### Examples
