/**
|
|
* MODULE NOTES:
|
|
* @update gess 4/1/98
|
|
*
|
|
* This virtual base class is used to define the basic
|
|
* tokenizer delegate interface. As you can see, it is
|
|
* very simple.
|
|
*
|
|
* The only routines we use at this point are getToken()
|
|
* and willAddToken(). While getToken() is obvious,
|
|
* willAddToken() may not be. The purpose of the method
|
|
* is to allow the delegate to decide whether or not a
|
|
* given token that was just read in the tokenization process
|
|
* should be included in the total list of tokens. This
|
|
* method gives you a chance to say, "No, ignore this token".
|
