All Implemented Interfaces:

DataBinding

public class TupleInputBinding
extends java.lang.Object
implements DataBinding

A concrete tuple binding for keys or values which are TupleInput objects. This binding is used when tuples themselves are the data object, rather than using application defined objects. A TupleInput must always be used. To convert a TupleOutput to a TupleInput, use the TupleInput.TupleInput(TupleOutput) constructor.
