351<DL>
352<DD>This constructor is used by the method "generateParseException"
353 in the generated parser.  Calling this constructor generates
354 a new object of this type with the fields "currentToken",
355 "expectedTokenSequences", and "tokenImage" set.  The boolean
356 flag "specialConstructor" is also set to true to indicate that
357 this constructor was used to create this object.
358 This constructor calls its super class with the empty string
359 to force the "toString" method of parent class "Throwable" to
360 print the error message in the form:
361     ParseException: <result of getMessage>

370<DL>
371<DD>The following constructors are for use by you for whatever
372 purpose you can think of.  Constructing the exception in this
373 manner makes the exception behave in the normal way - i.e., as
374 documented in the class "Throwable".  The fields "errorToken",
375 "expectedTokenSequences", and "tokenImage" do not contain
376 relevant information.  The JavaCC generated code does not use
377 these constructors.

403<DL>
404<DD>This method has the standard behavior when this object has been
405 created using the standard constructors.  Otherwise, it uses
406 "currentToken" and "expectedTokenSequences" to generate a parse
407 error message and returns it.  If this object has been created
408 due to a parse error, and you do not catch it (it gets thrown
409 from the parser), then this method is called during the printing
410 of the final stack trace, and hence the correct error message
411 gets displayed.
