Detailed Description

Timestamp tag for associating a timestamp with a packet.

It would have been more realistic to include this info in a header. Here we show how to avoid the extra overhead in a simulation.

Definition at line 38 of file timestamp-tag.h.

Constructor & Destructor Documentation

◆ TimestampTag() [1/2]

ns3::TimestampTag::TimestampTag ( )

default

Construct a new TimestampTag object.

◆ TimestampTag() [2/2]

ns3::TimestampTag::TimestampTag ( Time timestamp )

Construct a new TimestampTag object with the given timestamp.

Parameters

timestamp The timestamp

Definition at line 33 of file timestamp-tag.cc.

Member Function Documentation

◆ Deserialize()

void ns3::TimestampTag::Deserialize ( TagBuffer i )

overridevirtual

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.

Implements ns3::Tag.

Definition at line 67 of file timestamp-tag.cc.

References m_timestamp, and ns3::TagBuffer::ReadU64().

Here is the call graph for this function:

◆ GetInstanceTypeId()

TypeId ns3::TimestampTag::GetInstanceTypeId ( ) const

overridevirtual

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.
