| <DD>Returns a new Token object, by default. However, if you want, you |
| can create and return subclass objects based on the value of ofKind. |
| Simply add the cases to the switch for all those special cases. |
| For example, if you have a subclass of Token called IDToken that |
| you want to create if ofKind is ID, simply add something like : |
| |
| case MyParserConstants.ID : return new IDToken(ofKind, image); |
| |
| to the following switch statement. Then you can cast matchedToken |
| variable to the appropriate type and use sit in your lexical actions. |
