Class ParseTreeDebugParser

java.lang.Object
  antlr.Parser
      antlr.LLkParser
          antlr.debug.ParseTreeDebugParser

public class ParseTreeDebugParser

extends LLkParser

Override the standard matching and rule entry/exit routines to build parse trees. This class is useful for 2.7.3 where you can specify a superclass like class TinyCParser extends Parser(ParseTreeDebugParser);
