Class PropertyNode<T extends PropertyNode<T>>

java.lang.Object

org.zkoss.poi.hwpf.model.PropertyNode<T>

All Implemented Interfaces:

java.lang.Cloneable, java.lang.Comparable<T>

Direct Known Subclasses:

BytePropertyNode, CachedPropertyNode, GenericPropertyNode, SEPX, TextPiece

@Internal
public abstract class PropertyNode<T extends PropertyNode<T>>
extends java.lang.Object
implements java.lang.Comparable<T>, java.lang.Cloneable

Represents a lightweight node in the Trees used to store content properties. This only ever works in characters. For the few odd cases when the start and end aren't in characters (eg PAPX and CHPX), use BytePropertyNode between you and this.
