All Implemented Interfaces:

EntityBinding

public abstract class SerialSerialBinding

extends Object

implements EntityBinding

An abstract EntityBinding that treats an entity's key entry and data entry as serialized objects.

This class takes care of serializing and deserializing the key and data entry automatically. Its three abstract methods must be implemented by a concrete subclass to convert the deserialized objects to/from an entity object.

• entryToObject(Object,Object)
• objectToKey(Object)
• objectToData(Object)

Creates a serial-serial entity binding.

Parameters:

classCatalog - is the catalog to hold shared class information and for a database should be a StoredClassCatalog.

keyClass - is the key base class.

dataClass - is the data base class.

SerialSerialBinding

public SerialSerialBinding(SerialBinding keyBinding,
                           SerialBinding dataBinding)

Creates a serial-serial entity binding.

Parameters:

keyBinding - is the key binding.

dataBinding - is the data binding.
