public class TupleOutput
An OutputStream
with DataOutput
-like methods for
writing tuple fields. It is used by TupleBinding
.
This class has many methods that have the same signatures as methods in
the DataOutput
interface. The reason this class does not
implement DataOutput
is because it would break the interface
contract for those methods because of data format differences.
