Class ParseTreeDebugParser

java.lang.Object
  extended byantlr.Parser
      extended byantlr.LLkParser
          extended byantlr.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);

Method Summary
 int getNumberOfDerivationSteps()
           
 ParseTree getParseTree()
           
 void match(BitSet bitSet)
          Make sure current lookahead symbol matches the given set Throw an exception upon mismatch, which is catch by either the error handler or by the syntactic predicate.
 void match(int i)
          Make sure current lookahead symbol matches token type t.
 void matchNot(int i)
           
 void traceIn(java.lang.String s)
          Create a rule node, add to current tree, and make it current root
 void traceOut(java.lang.String s)
          Pop current root; back to adding to old root
