## 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.

    - #### 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.
