Class SerialSerialBinding<K,D,E>

java.lang.Object

com.sleepycat.bind.serial.SerialSerialBinding<K,D,E>

All Implemented Interfaces:

EntityBinding<E>

public abstract class SerialSerialBinding<K,D,E>
extends java.lang.Object
implements EntityBinding<E>

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<K> keyBinding,
                           SerialBinding<D> dataBinding)

Creates a serial-serial entity binding.

Parameters:

keyBinding - is the key binding.

dataBinding - is the data binding.
