// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
* Service Description: The service that an application uses to manipulate topics, and to send
* messages to a topic.
*
* To publish messages to a topic, see the Publisher class.
*
*
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 (TopicAdminClient topicAdminClient = TopicAdminClient.create()) {
* ProjectTopicName name = ProjectTopicName.of("[PROJECT]", "[TOPIC]");
* Topic response = topicAdminClient.createTopic(name);
* }
*
*
*
* Note: close() needs to be called on the topicAdminClient 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 TopicAdminSettings to
* create(). For example:
*
*
To customize credentials:
*
*
*
* TopicAdminSettings topicAdminSettings =
* TopicAdminSettings.newBuilder()
* .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
* .build();
* TopicAdminClient topicAdminClient =
* TopicAdminClient.create(topicAdminSettings);
*
*
*
* To customize the endpoint:
*
*
*
* TopicAdminSettings topicAdminSettings =
* TopicAdminSettings.newBuilder().setEndpoint(myEndpoint).build();
* TopicAdminClient topicAdminClient =
* TopicAdminClient.create(topicAdminSettings);
*
*
