Metadata()

virtual absl::optional< google::spanner::v1::ResultSetMetadata > google::cloud::spanner::ResultSourceInterface::Metadata ( )

pure virtualinherited

Returns metadata about the result set, such as the field types and the transaction id created by the request.

MOCK_METHOD() [1/3]

		Metadata	,
		()	,
		(override)
	)

MOCK_METHOD() [2/3]

		Stats	,
		()	,
		(const, override)

MOCK_METHOD() [3/3]

google::cloud::spanner_mocks::MockResultSetSource::MOCK_METHOD	(	StatusOr< spanner::Row >	,
		NextRow	,
		()	,
		(override)
	)

NextRow()

virtual StatusOr< spanner::Row > google::cloud::spanner::ResultSourceInterface::NextRow ( )

pure virtualinherited

Returns the next row in the stream.

Returns

if the stream is interrupted due to a failure the StatusOr<spanner::Row> contains the error. The function returns a successful StatusOr<> with an empty spanner::Row to indicate end-of-stream.

Stats()

virtual absl::optional< google::spanner::v1::ResultSetStats > google::cloud::spanner::ResultSourceInterface::Stats ( ) const

pure virtualinherited

Returns statistics about the result set, such as the number of rows, and the query plan used to compute the results.
