question: @ Override public void writeByteStream ( InputStream is ) throws IOException { while ( true ) { int len = SIZE - _offset - 3 ; if ( len < 16 ) { flushBuffer ( ) ; len = SIZE - _offset - 3 ; } len = is . read ( _buffer , _offset + 3 , len ) ; if ( len <= 0 ) { _buffer [ _offset ++ ] = BC_BINARY_DIRECT ; return ; } _buffer [ _offset + 0 ] = ( byte ) BC_BINARY_CHUNK ; _buffer [ _offset + 1 ] = ( byte ) ( len > > 8 ) ; _buffer [ _offset + 2 ] = ( byte ) ( len ) ; _offset += len + 3 ; } }
target:  Writes a full output stream.
