## com.sleepycat.bind.tuple
Class TupleMarshalledBinding<E extends MarshalledTupleEntry>

    java.lang.Object
      com.sleepycat.bind.tuple.TupleBase<E>
          com.sleepycat.bind.tuple.TupleBinding<E>
              com.sleepycat.bind.tuple.TupleMarshalledBinding<E>

All Implemented Interfaces:
  EntryBinding<E>

    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 Summary
`TupleMarshalledBinding(Class<E> cls)` Creates a tuple marshalled binding object.

Method Summary
`E` | `entryToObject(TupleInput input)` Constructs a key or data object from a `TupleInput` entry.
`void` | `objectToEntry(E object, TupleOutput output)` Converts a key or data object to a tuple entry.

Constructor Detail

### TupleMarshalledBinding

    public TupleMarshalledBinding(Class<E> cls)

  Creates a tuple marshalled binding object.

  The given class is used to instantiate key or data objects using `Class.forName(java.lang.String)`, 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.
