Method Detail

### addEscapes

    protected static final java.lang.String addEscapes(java.lang.String str)

  Replaces unprintable characters by their espaced (or unicode escaped) equivalents in the given string

### LexicalError

    private static final java.lang.String LexicalError(boolean EOFSeen,
                                                       int lexState,
                                                       int errorLine,
                                                       int errorColumn,
                                                       java.lang.String errorAfter,

  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.

### getMessage

    public java.lang.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.
  Overrides:
    `getMessage` in class `java.lang.Throwable`
