All Implemented Interfaces:

Serializable, CompositeData

public abstract class LazyCompositeData
extends Object
implements CompositeData, Serializable

This abstract class provides the implementation of the CompositeData interface. A CompositeData object will be lazily created only when the CompositeData interface is used. Classes that extends this abstract class will implement the getCompositeData() method. The object returned by the getCompositeData() is an instance of CompositeData such that the instance serializes itself as the type CompositeDataSupport.
