## org.apache.velocity.runtime.parser.node
Class ASTMethod

    java.lang.Object
      org.apache.velocity.runtime.parser.node.SimpleNode
          org.apache.velocity.runtime.parser.node.ASTMethod

All Implemented Interfaces:
  Node, Renderable

public class ASTMethod
extends SimpleNode

ASTMethod.java Method support for references : $foo.method() NOTE : introspection is now done at render time. Please look at the Parser.jjt file which is what controls the generation of this class.
