Package org.apache.velocity.runtime.visitor

Class NodeViewMode

java.lang.Object

org.apache.velocity.runtime.visitor.BaseVisitor

org.apache.velocity.runtime.visitor.NodeViewMode

All Implemented Interfaces:

StandardParserVisitor

public class NodeViewMode
extends BaseVisitor

This class is simply a visitor implementation that traverses the AST, produced by the Velocity parsing process, and creates a visual structure of the AST. This is primarily used for debugging, but it useful for documentation as well.
