question: private static State nextNormal ( final State state , final ByteArrayOutputStream line , final int next ) { final State result ; switch ( next ) { case '\r' : result = State . R ; break ; case '\"' : result = State . QUOTED_STRING ; break ; default : result = state ; line . write ( next ) ; break ; } return result ; }
target:  Maintain next symbol for current state = State.NORMAL.
