Package database is an auto-generated package for the Cloud Spanner Database Admin API.

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.

	InternalFetch func(pageSize int, pageToken string) (results []*databasepb.Backup, nextPageToken string, err error)
	// contains filtered or unexported fields
}

BackupIterator manages a stream of *databasepb.Backup.

func (*BackupIterator) Next

func (it *BackupIterator) Next() (*databasepb.Backup, 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 (*DatabaseAdminClient) UpdateDatabaseDdlOperation

func (c *DatabaseAdminClient) UpdateDatabaseDdlOperation(name string) *UpdateDatabaseDdlOperation

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

DatabaseIterator

type DatabaseIterator 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 []*databasepb.Database, nextPageToken string, err error)
	// contains filtered or unexported fields
}

DatabaseIterator manages a stream of *databasepb.Database.

func (*DatabaseIterator) Next

func (it *DatabaseIterator) Next() (*databasepb.Database, 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 (*DatabaseIterator) PageInfo

func (it *DatabaseIterator) 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) 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.

RestoreDatabaseOperation

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

RestoreDatabaseOperation manages a long-running operation from RestoreDatabase.

func (*RestoreDatabaseOperation) Done

func (op *RestoreDatabaseOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*RestoreDatabaseOperation) 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 (*RestoreDatabaseOperation) Name

func (op *RestoreDatabaseOperation) 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 (*RestoreDatabaseOperation) 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 (*RestoreDatabaseOperation) 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.

UpdateDatabaseDdlOperation

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