Class PullNode

java.lang.Object
- org.gjt.xpp.impl.tag.Tag
- - org.gjt.xpp.impl.tag.StartTag
  - - org.gjt.xpp.impl.node.Node
    - - org.gjt.xpp.impl.pullnode.PullNode

Implemented Interfaces:: XmlNode, XmlPullNode, XmlStartTag, XmlTag

public class PullNode

extends Node

implements XmlPullNode

Allows node tree to be constructed on demand. When PullNode is constructed and method setPullPasrser() is executed (or constructor with PullParser arg is called) node is assumend to be incomplete and children will be retrieved on demand (pulled) including automatic creation of sub pull nodes. If no pull parser is associated (it is null) this class must work like regular XmlNode...
