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::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::SocketAddressTag, ns3::SocketIpTtlTag, and ns3::SocketSetDontFragmentTag.

static TypeId ns3::Tag::GetTypeId

(

void

)

[static]

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

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

Reimplemented from ns3::ObjectBase.

Reimplemented in ns3::SocketAddressTag, ns3::SocketIpTtlTag, and ns3::SocketSetDontFragmentTag.

virtual void ns3::Tag::Print

(

std::ostream &

os

)

const [pure virtual]

Parameters:

os

the stream to print to

This method is typically invoked from the Packet::PrintByteTags or Packet::PrintPacketTags methods.

Implemented in ns3::SocketAddressTag, ns3::SocketIpTtlTag, and ns3::SocketSetDontFragmentTag.

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::SocketAddressTag, ns3::SocketIpTtlTag, and ns3::SocketSetDontFragmentTag.
