public interface LazyNode

extends org.w3c.dom.Node

Interface use to define Lazy DOM methods that apply to every node. In addition to these methods, each node must:

• Supply a getTemplateXXX for the specific node type.

  There are two basic interfaces for implementing LazyDOM nodes: LazyNode and LazyParent, with LazyParent extended LazyNode. They have the following properties:

  • Only LazyParent nodes can contain other nodes.
  • Only LazyParent nodes can exist with out their parent being expanded.
  • All children of a LazyParent are expanded if one of the children is expanded.
  • If a LazyNode that is not a LazyParent is expanded, its siblings are expanded.
  • If a LazyParent's parent is expanded, its siblings are expanded.
  • If a LazyParent's parent is not expanded, its siblings may or may not be expanded.
