Constructor & Destructor Documentation

◆ MyHeader()

◆ ~MyHeader()

virtual

Definition at line 50 of file main-packet-header.cc.

Member Function Documentation

◆ Deserialize()

uint32_t MyHeader::Deserialize ( Buffer::Iterator start )

virtual

Parameters

start an iterator which points to where the header should read from.

Returns: the number of bytes read.

This method is used by Packet::RemoveHeader to re-create a header from the byte buffer of a packet. The data read is expected to match bit-for-bit the representation of this header in real networks.

Note that data is not actually removed from the buffer to which the iterator points. Both Packet::RemoveHeader() and Packet::PeekHeader() call Deserialize(), but only the RemoveHeader() has additional statements to remove the header bytes from the underlying buffer and associated metadata.

Implements ns3::Header.

Definition at line 91 of file main-packet-header.cc.

References visualizer.core::start().

◆ GetData()

uint16_t MyHeader::GetData ( void ) const

Get the header data.

Returns: The data.

Definition at line 108 of file main-packet-header.cc.

◆ GetInstanceTypeId()

TypeId MyHeader::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.

Implements ns3::ObjectBase.

Definition at line 64 of file main-packet-header.cc.

◆ GetSerializedSize()

uint32_t MyHeader::GetSerializedSize ( void ) const

virtual

Returns: the expected size of the header.

This method is used by Packet::AddHeader to store a header into the byte buffer of a packet. This method should return the number of bytes which are needed to store the full header data by Serialize.

Implements ns3::Header.

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

◆ GetTypeId()

TypeId MyHeader::GetTypeId ( void )

static

Get the type ID.

Returns: the object TypeId

Definition at line 55 of file main-packet-header.cc.

References ns3::TypeId::SetParent().

◆ Print()

void MyHeader::Print ( std::ostream & os ) const

virtual

Parameters

os output stream This method is used by Packet::Print to print the content of a header as ascii data to a c++ output stream. Although the header is free to format its output as it wishes, it is recommended to follow a few rules to integrate with the packet pretty printer: start with flags, small field values located between a pair of parens. Values should be separated by whitespace. Follow the parens with the important fields, separated by whitespace. i.e.: (field1 val1 field2 val2 field3 val3) field4 val4 field5 val5

Implements ns3::Header.

Definition at line 70 of file main-packet-header.cc.

◆ Serialize()

void MyHeader::Serialize ( Buffer::Iterator start ) const

virtual

Parameters

start an iterator which points to where the header should be written.

This method is used by Packet::AddHeader to store a header into the byte buffer of a packet. The data written is expected to match bit-for-bit the representation of this header in a real network.

Implements ns3::Header.

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

References visualizer.core::start().

◆ SetData()

void MyHeader::SetData ( uint16_t data )

Set the header data.

Parameters

data The data.

Definition at line 103 of file main-packet-header.cc.
