question: @ Override public void write ( byte [ ] buffer , int offset , int length ) { if ( isClosed ( ) || isHead ( ) ) { return ; } int byteLength = _offset ; while ( true ) { int sublen = Math . min ( length , SIZE - byteLength ) ; System . arraycopy ( buffer , offset , _buffer , byteLength , sublen ) ; offset += sublen ; length -= sublen ; byteLength += sublen ; if ( length <= 0 ) { break ; } _offset = byteLength ; flushByteBuffer ( ) ; byteLength = _offset ; } _offset = byteLength ; }
target:  Writes a chunk of bytes to the stream.
