org.apache.velocity.runtime.parser.Parser
This class is responsible for parsing a Velocity template. This class was generated by JavaCC using the JJTree extension to produce an Abstract Syntax Tree (AST) of the template. Please look at the Parser.jjt file which is what controls the generation of this class. @author Jason van Zyl @author Geir Magnusson Jr. @version $Id: Parser.java,v 1.59 2001/04/22 18:03:59 geirm Exp $
