Static Public Member Functions

static TypeId GetTypeId (void)
 This method returns the TypeId associated to ns3::Tag.

Detailed Description

tag a set of bytes in a packet

New kinds of tags can be created by subclassing this base class.


Member Function Documentation

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::FlowIdTag, ns3::dot11s::HwmpTag, ns3::flame::FlameTag, ns3::QosTag, ns3::Ipv4PacketInfoTag, ns3::Ipv6PacketInfoTag, ns3::SocketAddressTag, ns3::SocketIpTtlTag, and ns3::SocketSetDontFragmentTag.

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.

Implemented in ns3::FlowIdTag, ns3::dot11s::HwmpTag, ns3::flame::FlameTag, ns3::QosTag, ns3::Ipv4PacketInfoTag, ns3::Ipv6PacketInfoTag, ns3::SocketAddressTag, ns3::SocketIpTtlTag, and ns3::SocketSetDontFragmentTag.

static TypeId ns3::Tag::GetTypeId ( void   )  [static]

This method returns the TypeId associated to ns3::Tag.

No Attributes defined for this type.
No TraceSources defined for this type.

Reimplemented from ns3::ObjectBase.

Reimplemented in ns3::FlowIdTag, ns3::dot11s::HwmpTag, ns3::flame::FlameTag, ns3::QosTag, ns3::Ipv4PacketInfoTag, ns3::Ipv6PacketInfoTag, ns3::SocketAddressTag, ns3::SocketIpTtlTag, and ns3::SocketSetDontFragmentTag.

virtual void ns3::Tag::Print ( std::ostream &  os  )  const [pure virtual]
virtual void ns3::Tag::Serialize ( TagBuffer  i  )  const [pure virtual]
Parameters:
i the buffer to write data into.

Write the content of the tag in the provided tag buffer. DO NOT attempt to write more bytes than you requested with Tag::GetSerializedSize.

Implemented in ns3::FlowIdTag, ns3::dot11s::HwmpTag, ns3::flame::FlameTag, ns3::QosTag, ns3::Ipv4PacketInfoTag, ns3::Ipv6PacketInfoTag, ns3::SocketAddressTag, ns3::SocketIpTtlTag, and ns3::SocketSetDontFragmentTag.
