For example: - \code - QPacketProtocol protocol(...); - - QPacket myPacket; - myPacket << "Hello world!" << 123; - protocol.send(myPacket); - \endcode - - As long as both ends of the connection are using the QPacketProtocol class, - the data within this packet will be delivered unfragmented at the other end, - ready for extraction. - - \code - QByteArray greeting; - int count; - - QPacket myPacket = protocol.read(); - - myPacket >> greeting >> count; - \endcode - - Only packets constructed from raw byte arrays may be read from. Empty QPacket - instances are for transmission only and are considered "write only". Attempting - to read data from them will result in undefined behavior. - - \ingroup io - \sa QPacketProtocol - */ - -int QPacket::s_dataStreamVersion = QDataStream::Qt_4_7; - -void QPacket::setDataStreamVersion(int dataStreamVersion) -{ - s_dataStreamVersion = dataStreamVersion; -} - -int QPacket::dataStreamVersion() -{ - return s_dataStreamVersion; -} - -/*! - Constructs an empty write-only packet. - */ -QPacket::QPacket() -{ - init(QIODevice::WriteOnly); -} - -/*! - Creates a copy of \a other.
