@Generated(value="by gapic-generator-java") public class StreamingServiceClient extends Object implements com.google.api.gax.core.BackgroundResource
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().
| Method | Description | Method Variants |
|---|---|---|
SendPackets |
Send packets to the series. |
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
|
ReceivePackets |
Receive packets from the series. |
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
|
ReceiveEvents |
Receive events given the stream name. |
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
|
AcquireLease |
AcquireLease acquires a lease. |
Request object method variants only take one parameter, a request object, which must be constructed before the call.
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
|
RenewLease |
RenewLease renews a lease. |
Request object method variants only take one parameter, a request object, which must be constructed before the call.
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
|
ReleaseLease |
RleaseLease releases a lease. |
Request object method variants only take one parameter, a request object, which must be constructed before the call.
Callable method variants take no parameters and return 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 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);
