Class ExecutionsClient

java.lang.Object
com.google.cloud.workflows.executions.v1.ExecutionsClient
All Implemented Interfaces:
BackgroundResource, AutoCloseable
@Generated("by gapic-generator-java") public class ExecutionsClient extends Object implements BackgroundResource
Service Description: Executions is used to start and manage running instances of [Workflows][google.cloud.workflows.v1.Workflow] called executions.

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 (ExecutionsClient executionsClient = ExecutionsClient.create()) {
   WorkflowName parent = WorkflowName.of("[PROJECT]", "[LOCATION]", "[WORKFLOW]");
   Execution execution = Execution.newBuilder().build();
   Execution response = executionsClient.createExecution(parent, execution);
 }

Note: close() needs to be called on the ExecutionsClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

ListExecutions

Returns a list of executions which belong to the workflow with the given name. The method returns executions of all workflow revisions. Returned executions are ordered by their start time (newest first).

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • listExecutions(ListExecutionsRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • listExecutions(WorkflowName parent)

  • listExecutions(String parent)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • listExecutionsPagedCallable()

  • listExecutionsCallable()

CreateExecution

Creates a new execution using the latest revision of the given workflow.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • createExecution(CreateExecutionRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • createExecution(WorkflowName parent, Execution execution)

  • createExecution(String parent, Execution execution)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • createExecutionCallable()

GetExecution

Returns an execution of the given name.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • getExecution(GetExecutionRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • getExecution(ExecutionName name)

  • getExecution(String name)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • getExecutionCallable()

CancelExecution

Cancels an execution of the given name.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • cancelExecution(CancelExecutionRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • cancelExecution(ExecutionName name)

  • cancelExecution(String name)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • cancelExecutionCallable()

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 ExecutionsSettings 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
 ExecutionsSettings executionsSettings =
     ExecutionsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ExecutionsClient executionsClient = ExecutionsClient.create(executionsSettings);

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
 ExecutionsSettings executionsSettings =
     ExecutionsSettings.newBuilder().setEndpoint(myEndpoint).build();
 ExecutionsClient executionsClient = ExecutionsClient.create(executionsSettings);

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
 ExecutionsSettings executionsSettings = ExecutionsSettings.newHttpJsonBuilder().build();
 ExecutionsClient executionsClient = ExecutionsClient.create(executionsSettings);
