LexicalError

protected static String LexicalError(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. Note: You can customize the lexical error message by modifying this method.

Parameters:

EOFSeen - indicates if EOF caused the lexicl error

lexState - 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

Returns:

TODO

getCharacter

public char getCharacter()

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.

Overrides:

getMessage in class Throwable

getPosition

public int getPosition()
