  antlr.DefineGrammarSymbols

All Implemented Interfaces:

ANTLRGrammarParseBehavior

Direct Known Subclasses:

MakeGrammar

public class DefineGrammarSymbols

extends java.lang.Object

implements ANTLRGrammarParseBehavior

DefineGrammarSymbols is a behavior for the ANTLRParser that adds all the token and rule symbols to the grammar symbol table. Token types are assigned to token symbols in this class also. The token type for a token is done in the order seen (lexically).
