◆ Deserialize()

void MyTag::Deserialize ( TagBuffer i)
overridevirtual
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.

Definition at line 84 of file main-packet-tag.cc.

References m_simpleValue, and ns3::TagBuffer::ReadU8().

+ Here is the call graph for this function:

◆ GetInstanceTypeId()

TypeId MyTag::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.

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

Implements ns3::ObjectBase.

Definition at line 66 of file main-packet-tag.cc.

References GetTypeId().

+ Here is the call graph for this function:

◆ GetSerializedSize()

uint32_t MyTag::GetSerializedSize ( ) const
overridevirtual
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 72 of file main-packet-tag.cc.

◆ GetSimpleValue()

uint8_t MyTag::GetSimpleValue ( ) const

Get the tag value.

Returns
the tag value.

Definition at line 102 of file main-packet-tag.cc.

References m_simpleValue.

+ Here is the caller graph for this function:

◆ GetTypeId()

TypeId MyTag::GetTypeId ( )
static

Get the type ID.

Returns
the object TypeId

+ Here is the caller graph for this function:

◆ Print()

void MyTag::Print ( std::ostream & os) const
overridevirtual
Parameters
osthe stream to print to

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

Implements ns3::Tag.

Definition at line 90 of file main-packet-tag.cc.

References m_simpleValue.

◆ Serialize()

void MyTag::Serialize ( TagBuffer i) const
overridevirtual
Parameters
ithe 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.

Implements ns3::Tag.

Definition at line 78 of file main-packet-tag.cc.

References m_simpleValue, and ns3::TagBuffer::WriteU8().

+ Here is the call graph for this function:

◆ SetSimpleValue()

void MyTag::SetSimpleValue ( uint8_t value)

Set the tag value.

Parameters
valueThe tag value.
