Class FlyweightEntity

java.lang.Object

org.dom4j.tree.AbstractNode

All Implemented Interfaces:

Direct Known Subclasses:

DefaultEntity

public class FlyweightEntity
extends AbstractEntity

FlyweightEntity is a Flyweight pattern implementation of a singly linked, read-only XML entity.

This node could be shared across documents and elements though it does not support the parent relationship.

Often this node needs to be created and then the text content added later (for example in SAX) so this implementation allows a call to setText(java.lang.String) providing the entity has no text already.
