Workflows API v1 - Package cloud.google.com/go/workflows/apiv1 (v1.13.2)

Package workflows is an auto-generated package for the Workflows API.

Manage workflow definitions. To execute workflows and manage executions, see the Workflows Executions API.

General documentation

For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:

Example usage

To get started with this package, create a client.

ctx := context.Background()
// 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://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := workflows.NewClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

ctx := context.Background()
// 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://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := workflows.NewClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

req := &workflowspb.CreateWorkflowRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/cloud.google.com/go/workflows/apiv1/workflowspb#CreateWorkflowRequest.
}
op, err := c.CreateWorkflow(ctx, req)
if err != nil {
    // TODO: Handle error.
}

resp, err := op.Wait(ctx)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

CallOptions

type CallOptions struct {
	ListWorkflows   []gax.CallOption
	GetWorkflow     []gax.CallOption
	CreateWorkflow  []gax.CallOption
	DeleteWorkflow  []gax.CallOption
	UpdateWorkflow  []gax.CallOption
	GetLocation     []gax.CallOption
	ListLocations   []gax.CallOption
	DeleteOperation []gax.CallOption
	GetOperation    []gax.CallOption
	ListOperations  []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

Client

type Client struct {

	// The call options for this service.
	CallOptions *CallOptions

	// LROClient is used internally to handle long-running operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient
	// contains filtered or unexported fields
}

Client is a client for interacting with Workflows API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Workflows is used to deploy and execute workflow programs. Workflows makes sure the program executes reliably, despite hardware and networking interruptions.

func NewClient

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient creates a new workflows client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

Workflows is used to deploy and execute workflow programs. Workflows makes sure the program executes reliably, despite hardware and networking interruptions.

Example

package main

import (
	"context"

	workflows "cloud.google.com/go/workflows/apiv1"
)

func main() {
	ctx := context.Background()
	// 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://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := workflows.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

func NewRESTClient

func NewRESTClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewRESTClient creates a new workflows rest client.

Workflows is used to deploy and execute workflow programs. Workflows makes sure the program executes reliably, despite hardware and networking interruptions.

Example

package main

import (
	"context"

	workflows "cloud.google.com/go/workflows/apiv1"
)

func main() {
	ctx := context.Background()
	// 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://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := workflows.NewRESTClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

func (*Client) Close

func (c *Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Client) Connection (deprecated)

func (c *Client) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated: Connections are now pooled so this method does not always return the same resource.

func (*Client) CreateWorkflow

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 error.

}

CreateWorkflowOperation manages a long-running operation from CreateWorkflow.

func (*CreateWorkflowOperation) Done

func (op *CreateWorkflowOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*CreateWorkflowOperation) Metadata

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*DeleteWorkflowOperation) Wait

func (op *DeleteWorkflowOperation) Wait(ctx context.Context, opts ...gax.CallOption) error

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

LocationIterator

type LocationIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// 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 []*locationpb.Location, nextPageToken string, err error)
	// contains filtered or unexported fields
}

LocationIterator manages a stream of *locationpb.Location.

func (*LocationIterator) All

func (it *LocationIterator) All() iter.Seq2[*locationpb.Location, error]

All returns an iterator. If an error is returned by the iterator, the iterator will stop after that iteration.

func (*LocationIterator) Next

func (it *LocationIterator) Next() (*locationpb.Location, 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 (*LocationIterator) PageInfo

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

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

OperationIterator

type OperationIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// 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 []*longrunningpb.Operation, nextPageToken string, err error)
	// contains filtered or unexported fields
}

OperationIterator manages a stream of *longrunningpb.Operation.

func (*OperationIterator) All

func (it *OperationIterator) All() iter.Seq2[*longrunningpb.Operation, error]

All returns an iterator. If an error is returned by the iterator, the iterator will stop after that iteration.

func (*OperationIterator) Next

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 (*OperationIterator) PageInfo

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

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

UpdateWorkflowOperation

type UpdateWorkflowOperation struct {
	// contains filtered or unexported fields
}

UpdateWorkflowOperation manages a long-running operation from UpdateWorkflow.

func (*UpdateWorkflowOperation) Done

func (op *UpdateWorkflowOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*UpdateWorkflowOperation) Metadata

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*UpdateWorkflowOperation) Name

func (op *UpdateWorkflowOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*UpdateWorkflowOperation) Poll

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*UpdateWorkflowOperation) Wait

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

WorkflowIterator

type WorkflowIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// 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 []*workflowspb.Workflow, nextPageToken string, err error)
	// contains filtered or unexported fields
}

WorkflowIterator manages a stream of *workflowspb.Workflow.

func (*WorkflowIterator) All

func (it *WorkflowIterator) All() iter.Seq2[*workflowspb.Workflow, error]

All returns an iterator. If an error is returned by the iterator, the iterator will stop after that iteration.

func (*WorkflowIterator) Next

func (it *WorkflowIterator) Next() (*workflowspb.Workflow, 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 (*WorkflowIterator) PageInfo

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

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