// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
* Service Description: Manages long-running operations with an API service.
*
* When an API method normally takes long time to complete, it can be designed to return
* [Operation][google.longrunning.Operation] to the client, and the client can use this interface to
* receive the real response asynchronously by polling the operation resource, or pass the operation
* resource to another API (such as Google Cloud Pub/Sub API) to receive the response. Any API
* service that returns long-running operations should implement the `Operations` interface so
* developers can have a consistent client experience.
*
*
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:
*
*
*
* try (OperationsClient operationsClient = OperationsClient.create()) {
* String name = "";
* Operation response = operationsClient.getOperation(name);
* }
*
*
*
* Note: close() needs to be called on the operationsClient 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.
*
*
* See the individual methods for example code.
*
*
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.
*
*
This class can be customized by passing in a custom instance of OperationsSettings to
* create(). For example:
*
*
To customize credentials:
*
*
*
* OperationsSettings operationsSettings =
* OperationsSettings.newBuilder()
* .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
* .build();
* OperationsClient operationsClient =
* OperationsClient.create(operationsSettings);
*
*
