51 \class QPacketProtocol -

52 \internal -

53 -

54 \brief The QPacketProtocol class encapsulates communicating discrete packets -

55 across fragmented IO channels, such as TCP sockets. -

56 -

57 QPacketProtocol makes it simple to send arbitrary sized data "packets" across -

58 fragmented transports such as TCP and UDP. -

59 -

60 As transmission boundaries are not respected, sending packets over protocols -

61 like TCP frequently involves "stitching" them back together at the receiver. -

62 QPacketProtocol makes this easier by performing this task for you. Packet -

63 data sent using QPacketProtocol is prepended with a 4-byte size header -

64 allowing the receiving QPacketProtocol to buffer the packet internally until -

65 it has all been received. QPacketProtocol does not perform any sanity -

66 checking on the size or on the data, so this class should only be used in -

67 prototyping or trusted situations where DOS attacks are unlikely. -

68 -

69 QPacketProtocol does not perform any communications itself. Instead it can -

70 operate on any QIODevice that supports the QIODevice::readyRead() signal. A -

71 logical "packet" is simply a QByteArray. The following example how to send -

72 data using QPacketProtocol. -

73 -

74 \code -

75 QTcpSocket socket; -

76 // ... connect socket ... -

77 -

78 QPacketProtocol protocol(&socket); -

79 -

80 // Send a packet -

81 QDataStream packet; -

82 packet << "Hello world" << 123; -

83 protocol.send(packet.data()); -

84 \endcode -

85 -

86 Likewise, the following shows how to read data from QPacketProtocol, assuming -

87 that the QPacketProtocol::readyRead() signal has been emitted. -

88 -

89 \code -

90 // ... QPacketProtocol::readyRead() is emitted ... -

91 -

92 int a; -

93 QByteArray b; -

94 -

95 // Receive packet -

96 QDataStream packet(protocol.read()); -

97 p >> a >> b; -

98 \endcode -

99 -
