424<DL>
425<DD>Returns a new Token object, by default. However, if you want, you
426 can create and return subclass objects based on the value of ofKind.
427 Simply add the cases to the switch for all those special cases.
428 For example, if you have a subclass of Token called IDToken that
429 you want to create if ofKind is ID, simlpy add something like :
430
431    case MyParserConstants.ID : return new IDToken();
432
433 to the following switch statement. Then you can cast matchedToken
434 variable to the appropriate type and use it in your lexical actions.
