if not derived from another grammar, might still specify a non-ANTLR class to derive from like this "class T extends Parser(MyParserClass);"

Constructor Detail

Grammar

public Grammar(Tool tool, String name, String superGrammar, IndexedVector rules)

Method Detail

Copy all nonoverridden rules, vocabulary, and options into this grammar from supergrammar chain. The change is made in place; e.g., this grammar's vector of rules gets bigger. This has side-effects: all grammars on path to root of hierarchy are expanded also.
