◆ Deserialize()

void ns3::SocketSetDontFragmentTag::Deserialize ( TagBuffer  i)
virtual
Parameters
ithe 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.

Implements ns3::Tag.

◆ GetInstanceTypeId()

TypeId ns3::SocketSetDontFragmentTag::GetInstanceTypeId ( void  ) const
virtual

Get the most derived TypeId for this Object.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

Returns
The TypeId associated to the most-derived type of this instance.

◆ GetSerializedSize()

uint32_t ns3::SocketSetDontFragmentTag::GetSerializedSize ( void  ) const
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.

Implements ns3::Tag.

Definition at line 755 of file socket.cc.

References NS_LOG_FUNCTION.

◆ GetTypeId()

TypeId ns3::SocketSetDontFragmentTag::GetTypeId ( void  )
static

Get the type ID.

Returns
the object TypeId

◆ IsEnabled()

bool ns3::SocketSetDontFragmentTag::IsEnabled ( void  ) const

Checks if the DF (Don't Fragment) flag is set.

Returns
true if DF is set.

References m_dontFragment, and NS_LOG_FUNCTION.

◆ Print()

void ns3::SocketSetDontFragmentTag::Print ( std::ostream &  os) const
virtual
Parameters
osthe stream to print to

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

◆ Serialize()

void ns3::SocketSetDontFragmentTag::Serialize ( TagBuffer  i) const
