[antlr-interest] Passing information from main program to lexer, parser and tree walker

[Cameron Esfahani]

So, for example, I could create an InformationBuffer class, and then  
add a setInformationBuffer/getInformationBuffer pair of routines to  
the lexer, parser and tree walker.

After creating the lexer, parser and tree walker, I can call  
setInformationBuffer() to pass them the relevant information:

		ANTLRInputStream		input = new ANTLRInputStream( System.in );

		// create a lexer that feeds off of input CharStream
		TLexer					lexer = new TLexer( input );

		.....
		lexer.setInformationBuffer( info );

Something like that?
