virtual void ns3::Tag::Deserialize ( TagBuffer  i )

pure virtual

Parameters

i	the buffer to read data from.

Read the content of the tag from the provided tag buffer. DO NOT attempt to read more bytes than you wrote with Tag::Serialize.

Implemented in ns3::SocketIpv6TclassTag, ns3::SocketIpTosTag, ns3::SocketSetDontFragmentTag, ns3::SocketIpv6HopLimitTag, ns3::SocketIpTtlTag, ns3::SocketAddressTag, ns3::AnimByteTag, BenchTag< N >, ns3::aodv::DeferredRouteOutputTag, ns3::QosTag, ns3::dsdv::DeferredRouteOutputTag, ns3::LteRadioBearerTag, ns3::PyVizPacketTag, ns3::flame::FlameTag, ns3::Ipv6PacketInfoTag, ns3::Ipv4PacketInfoTag, ns3::dot11s::HwmpTag, anonymous_namespace{packet-test-suite.cc}::ATestTag< N >, ns3::TxModeTag, ns3::PdcpTag, ns3::SnrTag, ns3::RlcTag, ns3::LtePhyTag, ns3::Ipv4FlowProbeTag, ns3::LteRlcSduStatusTag, MyTag, ns3::FlowIdTag, and ns3::DelayJitterEstimationTimestampTag.

Here is the caller graph for this function:

virtual uint32_t ns3::Tag::GetSerializedSize ( void  ) const

pure virtual

Returns

the number of bytes required to serialize the data of the tag.

This method is typically invoked by Packet::AddPacketTag or Packet::AddByteTag just prior to calling Tag::Serialize.
