    public class TupleMarshalledBinding<E extends MarshalledTupleEntry>
    extends TupleBinding<E>

A concrete `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.

### Constructor Detail

#### TupleMarshalledBinding

    public TupleMarshalledBinding(java.lang.Class<E> cls)

Creates a tuple marshalled binding object.

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.

Parameters:
  `cls` - is the class of the key or data objects.

### Method Detail

#### entryToObject

    public E entryToObject(TupleInput input)

Description copied from class: `TupleBinding`
Constructs a key or data object from a `TupleInput` entry.

Specified by:
  `entryToObject` in class `TupleBinding<E extends MarshalledTupleEntry>`
Parameters:
  `input` - is the tuple key or data entry.
Returns:
  the key or data object constructed from the entry.

#### objectToEntry

    public void objectToEntry(E object,
                              TupleOutput output)

Description copied from class: `TupleBinding`
Converts a key or data object to a tuple entry.

Specified by:
  `objectToEntry` in class `TupleBinding<E extends MarshalledTupleEntry>`
Parameters:
  `object` - is the key or data object.
  `output` - is the tuple entry to which the key or data should be written.
