## Class TupleTupleMarshalledBinding<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>

- java.lang.Object
- - com.sleepycat.bind.tuple.TupleBase<E>
  - - com.sleepycat.bind.tuple.TupleTupleBinding<E>
    - - com.sleepycat.bind.tuple.TupleTupleMarshalledBinding<E>

- All Implemented Interfaces:
    EntityBinding<E>

      public class TupleTupleMarshalledBinding<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>
      extends TupleTupleBinding<E>

  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.

    - #### TupleTupleMarshalledBinding

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

      Creates a tuple-tuple marshalled binding object.

      The given class is used to instantiate entity objects using `Class.newInstance()`, 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 E 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<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>`
      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(E object,
                                  TupleOutput output)

      Description copied from class: `TupleTupleBinding`
      Extracts a key tuple from an entity object.
      Specified by:
        `objectToKey` in class `TupleTupleBinding<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>`
      Parameters:
        `object` - is the entity object.
        `output` - is the `TupleOutput` to which the key should be written.

    - #### objectToData

          public void objectToData(E object,
                                   TupleOutput output)

      Description copied from class: `TupleTupleBinding`
      Extracts a key tuple from an entity object.
      Specified by:
        `objectToData` in class `TupleTupleBinding<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>`
      Parameters:
        `object` - is the entity object.
        `output` - is the `TupleOutput` to which the data should be written.
