question: public static byte [ ] escape ( final byte [ ] bytes ) { final byte [ ] temp = new byte [ 2 * bytes . length ] ; int currentPosition = 0 ; for ( final byte b : bytes ) { if ( b == ESCAPE_CHAR ) { temp [ currentPosition ++ ] = ESCAPE_CHAR ; temp [ currentPosition ++ ] = REPLACEMENT_CHAR ; } else if ( b == DELIMITER ) { temp [ currentPosition ++ ] = ESCAPE_CHAR ; temp [ currentPosition ++ ] = ESCAPE_CHAR ; } else { temp [ currentPosition ++ ] = b ; } } final byte [ ] escaped = new byte [ currentPosition ] ; System . arraycopy ( temp , 0 , escaped , 0 , currentPosition ) ; return escaped ; }
target:  Escapes the provided string so that it no longer contains the Constants.DELIMITER character.
