Package com.google.cloud.workflows.v1

Class WorkflowsClient

java.lang.Object
com.google.cloud.workflows.v1.WorkflowsClient
All Implemented Interfaces:
BackgroundResource, AutoCloseable
@Generated("by gapic-generator-java") public class WorkflowsClient extends Object implements BackgroundResource
Service Description: Workflows is used to deploy and execute workflow programs. Workflows makes sure the program executes reliably, despite hardware and networking interruptions.

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 (WorkflowsClient workflowsClient = WorkflowsClient.create()) {
   WorkflowName name = WorkflowName.of("[PROJECT]", "[LOCATION]", "[WORKFLOW]");
   Workflow response = workflowsClient.getWorkflow(name);
 }

Note: close() needs to be called on the WorkflowsClient 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

ListWorkflows

Lists workflows in a given project and location. The default order is not specified.

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

  • listWorkflows(ListWorkflowsRequest request)

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

  • listWorkflows(LocationName parent)

  • listWorkflows(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.

  • listWorkflowsPagedCallable()

  • listWorkflowsCallable()

GetWorkflow

Gets details of a single workflow.

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

  • getWorkflow(GetWorkflowRequest request)

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

  • getWorkflow(WorkflowName name)

  • getWorkflow(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.

  • getWorkflowCallable()

CreateWorkflow

Creates a new workflow. If a workflow with the specified name already exists in the specified project and location, the long running operation returns a [ALREADY_EXISTS][google.rpc.Code.ALREADY_EXISTS] error.

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

  • createWorkflowAsync(CreateWorkflowRequest request)

Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service.

  • createWorkflowAsync(LocationName parent, Workflow workflow, String workflowId)

  • createWorkflowAsync(String parent, Workflow workflow, String workflowId)

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

  • createWorkflowOperationCallable()

  • createWorkflowCallable()

DeleteWorkflow

Deletes a workflow with the specified name. This method also cancels and deletes all running executions of the workflow.

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

  • deleteWorkflowAsync(DeleteWorkflowRequest request)

Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service.

  • deleteWorkflowAsync(WorkflowName name)

  • deleteWorkflowAsync(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.

  • deleteWorkflowOperationCallable()

  • deleteWorkflowCallable()

UpdateWorkflow

Updates an existing workflow. Running this method has no impact on already running executions of the workflow. A new revision of the workflow might be created as a result of a successful update operation. In that case, the new revision is used in new workflow executions.

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

  • updateWorkflowAsync(UpdateWorkflowRequest request)

Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service.

  • updateWorkflowOperationCallable()

  • updateWorkflowCallable()

ListWorkflowRevisions

Lists revisions for a given workflow.

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

  • listWorkflowRevisions(ListWorkflowRevisionsRequest request)

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

  • listWorkflowRevisionsPagedCallable()

  • listWorkflowRevisionsCallable()

ListLocations

Lists information about the supported locations for this service.

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

  • listLocations(ListLocationsRequest request)

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

  • getLocation(GetLocationRequest request)

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

  • getLocationCallable()

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 WorkflowsSettings 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
 WorkflowsSettings workflowsSettings =
     WorkflowsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 WorkflowsClient workflowsClient = WorkflowsClient.create(workflowsSettings);

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
 WorkflowsSettings workflowsSettings =
     WorkflowsSettings.newBuilder().setEndpoint(myEndpoint).build();
 WorkflowsClient workflowsClient = WorkflowsClient.create(workflowsSettings);

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
 WorkflowsSettings workflowsSettings = WorkflowsSettings.newHttpJsonBuilder().build();
 WorkflowsClient workflowsClient = WorkflowsClient.create(workflowsSettings);
