Returns a detailed message for the Error when it is thrown by the token manager to indicate a lexical error. Parameters : EOFSeen : indicates if EOF caused the lexicl error curLexState : lexical state in which this error occured errorLine : line number when the error occured errorColumn : column number when the error occured errorAfter : prefix that was seen before this error occured curchar : the offending character Note: You can customize the lexical error message by modifying this method.
 
    protected static String LexicalError(boolean EOFSeenint lexStateint errorLineint errorColumnString errorAfterchar curChar) {
       return("Lexical error at line " +
            errorLine + ", column " +
           errorColumn + ".  Encountered: " +
           (EOFSeen ? "<EOF> " : ("\"" + addEscapes(String.valueOf(curChar)) + "\"") + " (" + (int)curChar + "), ") +
           "after : \"" + addEscapes(errorAfter) + "\"");
   }

   
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.
   public String getMessage() {
      return super.getMessage();

   public TokenMgrError(String messageint reason) {
      super(message);
       = reason;
