## com.sleepycat.bind.tuple
Class TupleTupleMarshalledBinding

    java.lang.Object
      com.sleepycat.bind.tuple.TupleTupleBinding
          com.sleepycat.bind.tuple.TupleTupleMarshalledBinding

All Implemented Interfaces:
  EntityBinding

public class TupleTupleMarshalledBinding
extends TupleTupleBinding

A concrete `TupleTupleBinding` that delegates to the `MarshalledTupleEntry` and `MarshalledTupleKeyEntity` interfaces of the entity class.

This class calls the methods of the `MarshalledTupleEntry` interface to convert between the data entry and entity object. It calls the methods of the `MarshalledTupleKeyEntity` interface to convert between the key entry and the entity object. These two interfaces must both be implemented by the entity class.

Constructor Summary
`TupleTupleMarshalledBinding(Class cls)` Creates a tuple-tuple marshalled binding object.

Method Summary
`Object` | `entryToObject(TupleInput keyInput, TupleInput dataInput)` Constructs an entity object from `TupleInput` key and data entries.
`void` | `objectToData(Object object, TupleOutput output)` Extracts a key tuple from an entity object.
`void` | `objectToKey(Object object, TupleOutput output)` Extracts a key tuple from an entity object.

Constructor Detail

### TupleTupleMarshalledBinding

    public TupleTupleMarshalledBinding(Class cls)

  Creates a tuple-tuple marshalled binding object.

  The given class is used to instantiate entity 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` and `MarshalledTupleKeyEntity` interfaces.

Parameters:
  `cls` - is the class of the entity objects.

Method Detail

### entryToObject

    public Object entryToObject(TupleInput keyInput,
                                TupleInput dataInput)

  Description copied from class: `TupleTupleBinding`
  Constructs an entity object from `TupleInput` key and data entries.

  Specified by:
    `entryToObject` in class `TupleTupleBinding`
  Parameters:
    `keyInput` - is the `TupleInput` key entry object.
    `dataInput` - is the `TupleInput` data entry object.
  Returns:
    the entity object constructed from the key and data.

### objectToKey

    public void objectToKey(Object object,
                            TupleOutput output)

  Description copied from class: `TupleTupleBinding`
  Extracts a key tuple from an entity object.

  Specified by:
    `objectToKey` in class `TupleTupleBinding`
  Parameters:
    `object` - is the entity object.
    `output` - is the `TupleOutput` to which the key should be written.

### objectToData

    public void objectToData(Object object,
                             TupleOutput output)

  Description copied from class: `TupleTupleBinding`
  Extracts a key tuple from an entity object.

  Specified by:
    `objectToData` in class `TupleTupleBinding`
  Parameters:
    `object` - is the entity object.
    `output` - is the `TupleOutput` to which the data should be written.
