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.

static String de.fraunhofer.isst.axbench.axlang.parser.TokenMgrError.LexicalError	(	boolean	EOFSeen,
		int	lexState,
		int	errorLine,
		int	errorColumn,
		String	errorAfter,
		char	curChar
	)			[static, protected]

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 lexical error curLexState : lexical state in which this error occurred errorLine : line number when the error occurred errorColumn : column number when the error occurred errorAfter : prefix that was seen before this error occurred curchar : the offending character Note: You can customize the lexical error message by modifying this method.
