java.beans.PersistenceDelegate

Direct Known Subclasses:

public abstract class PersistenceDelegate
extends java.lang.Object

A PersistenceDelegate describes how a another object has to constructed and transformed in order to create a complete replicate.

For custom classes you will need to implement PersistenceDelegate in a way that is suitable for them. To make use of the implementation you have to register it with an Encoder using the {Encoder#setPersistenceDelegate} method.
