Parameters :
EOFSeen : indicates if EOF caused the lexicl error
curLexState : lexical state in which this error occured

getMessage
public String getMessage()
- You can also modify the body of this method to customize your error messages.
For example, cases like LOOP_DETECTED and INVALID_LEXICAL_STATE are not
of end-users concern, so you can return something like :
"Internal Error : Please file a bug report .... "
from this method for such cases in the release version of your parser.
