boolean antlr.LexerGrammar.filterMode = false [protected] |
true if lexer is to ignore all unrecognized tokens

String antlr.LexerGrammar.filterRule = null [protected] |
if filterMode is true, then filterRule can indicate an optional rule to use as the scarf language. If null, programmer used plain "filter=true" not "filter=rule".
