type CreateDatabaseOperation ¶

CreateDatabaseOperation manages a long-running operation from CreateDatabase.

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

func (*CreateDatabaseOperation) Done ¶

func (op *CreateDatabaseOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*CreateDatabaseOperation) Metadata ¶

func (op *CreateDatabaseOperation) Metadata() (*databasepb.CreateDatabaseMetadata, error)

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 (*CreateDatabaseOperation) Name ¶

func (op *CreateDatabaseOperation) 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 (*CreateDatabaseOperation) Poll ¶

func (op *CreateDatabaseOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*databasepb.Database, error)

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 (*CreateDatabaseOperation) Wait ¶

func (op *CreateDatabaseOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*databasepb.Database, 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.
