public  TokenMgrError(boolean EOFSeen, int lexState, int errorLine, int errorColumn, String errorAfter, char curChar, int reason)
    

Method Summary
protected static  StringLexicalError(boolean EOFSeen, int lexState, int errorLine, int errorColumn, String errorAfter, char curChar)
     Returns a detailed message for the Error when it is thrown by the token manager to indicate a lexical error.
