EntryBinding<E>
public class TupleMarshalledBinding<E extends MarshalledTupleEntry> extends TupleBinding<E>
TupleBinding
that delegates to the
MarshalledTupleEntry
interface of the data or key object.
This class works by calling the methods of the MarshalledTupleEntry
interface, which must be implemented by the key or
data class, to convert between the key or data entry and the object.

public TupleMarshalledBinding(java.lang.Class<E> cls)
The given class is used to instantiate key or data objects using
Class.newInstance()
, and therefore must be a public class and have
a public no-arguments constructor. It must also implement the MarshalledTupleEntry
interface.
