## com.sleepycat.bind.serial
Class TupleSerialMarshalledBinding

    java.lang.Object
      com.sleepycat.bind.serial.TupleSerialBinding
          com.sleepycat.bind.serial.TupleSerialMarshalledBinding

All Implemented Interfaces:
  EntityBinding

public class TupleSerialMarshalledBinding
extends TupleSerialBinding

A concrete `TupleSerialBinding` that delegates to the `MarshalledTupleKeyEntity` interface of the entity class.

The `MarshalledTupleKeyEntity` interface must be implemented by the entity class to convert between the key/data entry and entity object.

The binding is "tricky" in that it uses the entity class for both the stored data entry and the combined entity object. To do this, the entity's key field(s) are transient and are set by the binding after the data object has been deserialized. This avoids the use of a "data" class completely.

Constructor Detail

### TupleSerialMarshalledBinding

    public TupleSerialMarshalledBinding(ClassCatalog classCatalog,
                                        Class baseClass)

  Creates a tuple-serial marshalled binding object.

Parameters:
  `classCatalog` - is the catalog to hold shared class information and for a database should be a `StoredClassCatalog`.
  `baseClass` - is the base class for serialized objects stored using this binding -- all objects using this binding must be an instance of this class.

### TupleSerialMarshalledBinding

    public TupleSerialMarshalledBinding(SerialBinding dataBinding)

  Creates a tuple-serial marshalled binding object.

Parameters:
  `dataBinding` - is the binding used for serializing and deserializing the entity object.

Method Detail

### entryToObject

    public Object entryToObject(TupleInput tupleInput,
                                Object javaInput)

  Description copied from class: `TupleSerialBinding`
  Constructs an entity object from `TupleInput` key entry and deserialized data entry objects.

  Specified by:
    `entryToObject` in class `TupleSerialBinding`
  Parameters:
    `tupleInput` - is the `TupleInput` key entry object.
    `javaInput` - is the deserialized 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: `TupleSerialBinding`
  Extracts a key tuple from an entity object.

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

### objectToData

    public Object objectToData(Object object)

  Description copied from class: `TupleSerialBinding`
  Extracts a data object from an entity object.

  Specified by:
    `objectToData` in class `TupleSerialBinding`
  Parameters:
    `object` - is the entity object.
  Returns:
    the deserialized data object.
