Class StreamingServiceClient
- All Implemented Interfaces:
BackgroundResource,AutoCloseable
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:
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in
// https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
try (StreamingServiceClient streamingServiceClient = StreamingServiceClient.create()) {
AcquireLeaseRequest request =
AcquireLeaseRequest.newBuilder()
.setSeries("series-905838985")
.setOwner("owner106164915")
.setTerm(Duration.newBuilder().build())
.setLeaseType(LeaseType.forNumber(0))
.build();
Lease response = streamingServiceClient.acquireLease(request);
}
Note: close() needs to be called on the StreamingServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

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 StreamingServiceSettings to create(). For example:
To customize credentials:
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in
// https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
StreamingServiceSettings streamingServiceSettings =
StreamingServiceSettings.newBuilder()
.setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
.build();
StreamingServiceClient streamingServiceClient =
StreamingServiceClient.create(streamingServiceSettings);
To customize the endpoint:
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in
// https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
StreamingServiceSettings streamingServiceSettings =
StreamingServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
StreamingServiceClient streamingServiceClient =
StreamingServiceClient.create(streamingServiceSettings);
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in
// https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
StreamingServiceSettings streamingServiceSettings =
StreamingServiceSettings.newHttpJsonBuilder().build();
StreamingServiceClient streamingServiceClient =
StreamingServiceClient.create(streamingServiceSettings);
