question: private void handleEnd ( GuacamoleInstruction instruction ) { List < String > args = instruction . getArgs ( ) ; if ( args . size ( ) < 1 ) return ; closeInterceptedStream ( args . get ( 0 ) ) ; }
target:  Handles a single "end" instruction, closing the associated OutputStream. If no OutputStream is associated with the stream index within the "end" instruction, this function has no effect.
