func (*WorkflowTemplateClient) GetWorkflowTemplate 

func (c *WorkflowTemplateClient) GetWorkflowTemplate(ctx context.Context, req *dataprocpb.GetWorkflowTemplateRequest, opts ...gax.CallOption) (*dataprocpb.WorkflowTemplate, error)

GetWorkflowTemplate retrieves the latest workflow template.

Can retrieve previously instantiated template by specifying optional version parameter.

Example 
ctx := context.Background()
c, err := dataproc.NewWorkflowTemplateClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dataprocpb.GetWorkflowTemplateRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.GetWorkflowTemplate(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Output:

func (*WorkflowTemplateClient) InstantiateWorkflowTemplate 

func (c *WorkflowTemplateClient) InstantiateWorkflowTemplate(ctx context.Context, req *dataprocpb.InstantiateWorkflowTemplateRequest, opts ...gax.CallOption) (*InstantiateWorkflowTemplateOperation, error)

InstantiateWorkflowTemplate instantiates a template and begins execution.

The returned Operation can be used to track execution of workflow by polling [operations.get][google.longrunning.Operations.GetOperation]. The Operation will complete when entire workflow is finished.

The running workflow can be aborted via [operations.cancel][google.longrunning.Operations.CancelOperation]. This will cause any inflight jobs to be cancelled and workflow-owned clusters to be deleted.

The [Operation.metadata][google.longrunning.Operation.metadata] will be [WorkflowMetadata][google.cloud.dataproc.v1beta2.WorkflowMetadata].

On successful completion, [Operation.response][google.longrunning.Operation.response] will be [Empty][google.protobuf.Empty].

Example 
ctx := context.Background()
c, err := dataproc.NewWorkflowTemplateClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dataprocpb.InstantiateWorkflowTemplateRequest{
	// TODO: Fill request struct fields.
}
op, err := c.InstantiateWorkflowTemplate(ctx, req)
if err != nil {
	// TODO: Handle error.
}

err = op.Wait(ctx)
// TODO: Handle error.

Output:

func (*WorkflowTemplateClient) InstantiateWorkflowTemplateOperation 

func (c *WorkflowTemplateClient) InstantiateWorkflowTemplateOperation(name string) *InstantiateWorkflowTemplateOperation

InstantiateWorkflowTemplateOperation returns a new InstantiateWorkflowTemplateOperation from a given name. The name must be that of a previously created InstantiateWorkflowTemplateOperation, possibly from a different process.

func (*WorkflowTemplateClient) ListWorkflowTemplates 

func (c *WorkflowTemplateClient) ListWorkflowTemplates(ctx context.Context, req *dataprocpb.ListWorkflowTemplatesRequest, opts ...gax.CallOption) *WorkflowTemplateIterator

ListWorkflowTemplates lists workflows that match the specified filter in the request.

Example 
ctx := context.Background()
c, err := dataproc.NewWorkflowTemplateClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dataprocpb.ListWorkflowTemplatesRequest{
	// TODO: Fill request struct fields.
}
it := c.ListWorkflowTemplates(ctx, req)
for {
	resp, err := it.Next()
	if err == iterator.Done {
		break
	}
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*WorkflowTemplateClient) UpdateWorkflowTemplate 

func (c *WorkflowTemplateClient) UpdateWorkflowTemplate(ctx context.Context, req *dataprocpb.UpdateWorkflowTemplateRequest, opts ...gax.CallOption) (*dataprocpb.WorkflowTemplate, error)

UpdateWorkflowTemplate updates (replaces) workflow template. The updated template must contain version that matches the current server version.

Example 
ctx := context.Background()
c, err := dataproc.NewWorkflowTemplateClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dataprocpb.UpdateWorkflowTemplateRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.UpdateWorkflowTemplate(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Output:

type WorkflowTemplateIterator 

type WorkflowTemplateIterator struct {

	// InternalFetch is for use by the Google Cloud Libraries only.
	// It is not part of the stable interface of this package.
	//
	// InternalFetch returns results from a single call to the underlying RPC.
	// The number of results is no greater than pageSize.
	// If there are no more results, nextPageToken is empty and err is nil.
	InternalFetch func(pageSize int, pageToken string) (results []*dataprocpb.WorkflowTemplate, nextPageToken string, err error)
	// contains filtered or unexported fields
}

WorkflowTemplateIterator manages a stream of *dataprocpb.WorkflowTemplate.

func (*WorkflowTemplateIterator) Next 

func (it *WorkflowTemplateIterator) Next() (*dataprocpb.WorkflowTemplate, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*WorkflowTemplateIterator) PageInfo 

func (it *WorkflowTemplateIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.
