/**
* An wrapper class of {@link InternalPhotosLibraryClient}.
*
* Client to interact with the Google Photos Library API. You can perform the following actions
* on behalf of the user:
*
*
* - upload media items directly to their Google Photos library
*
- create albums
*
- add media items (including album enrichments) to albums
*
- list and download content from their Google Photos library
*
- filter results by media type, date range or content category
*
- create, join, and access shared albums
*
*
* This class provides the ability to make remote calls to the backing service through method
* calls that map to API methods. Sample code to get started:
*
*
*
* PhotosLibrarySettings photosLibrarySettings =
* PhotosLibrarySettings.newBuilder()
* .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
* .build();
* try (PhotosLibraryClient photosLibraryClient =
* PhotosLibraryClient.initialize(photosLibrarySettings)) {
* Album createdAlbum = photosLibraryClient.createAlbum("My Album");
* }
*
*
*
* Note: close() needs to be called on the photosLibraryClient object to clean up resources such
* as threads. In the example above, try-with-resources is used, which automatically calls close().
*
*
The surface of this class includes several types of Java methods for each of the API's
* methods:
*
*
* - A "flattened" method. With this type of method, the fields of the request type have been
* converted into function parameters. It may be the case that not all fields are available as
* parameters, and not every API method will have a flattened method entry point.
*
- A "request object" method. This type of method only takes one parameter, a request object,
* which must be constructed before the call. Not every API method will have a request object
* method.
*
- A "callable" method. This type of method takes no parameters and returns an immutable API
* callable object, which can be used to initiate calls to the service.
*
*
* Many parameters require resource names to be formatted in a particular way. To assist with
* these names, this class includes a format method for each type of name, and additionally a parse
* method to extract the individual identifiers contained within names that are returned.
*
*
Do not use {@link PhotosLibraryClient#create()} or {@link
* PhotosLibraryClient#create(InternalPhotosLibrarySettings)} for this wrapper.
