question: @ Override public void write ( byte [ ] buf , int offset , int length , boolean isEnd ) throws IOException { if ( _s == null ) { return ; } try { _needsFlush = true ; while ( length > 0 ) { _writeBuffer . clear ( ) ; int sublen = Math . min ( length , _writeBuffer . remaining ( ) ) ; _writeBuffer . put ( buf , offset , sublen ) ; _writeBuffer . flip ( ) ; _s . write ( _writeBuffer ) ; length -= sublen ; offset += sublen ; } _totalWriteBytes += length ; } catch ( IOException e ) { IOException exn = ClientDisconnectException . create ( this + ":" + e , e ) ; try { close ( ) ; } catch ( IOException e1 ) { } throw exn ; } }
target:  Writes bytes to the socket.
