Member Function Documentation

Deserialize()

void MyTag::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 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 provided by ns3::Object::GetInstanceTypeId but classes which derive from ns3::ObjectBase directly have to implement it themselves. Typically, this method should simply return the output of GetTypeId().

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

os	the 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

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.

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

value

The tag value.
