Member Function Documentation

◆ Deserialize()

uint32_t ns3::Icmpv4TimeExceeded::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.

◆ GetData()

void ns3::Icmpv4TimeExceeded::GetData ( uint8_t payload[8] ) const

Get the ICMP carried data.

Parameters

payload the data (filled)

◆ GetHeader()

Ipv4Header ns3::Icmpv4TimeExceeded::GetHeader ( void ) const

Get the ICMP carried IPv4 header.

Returns: the header

References m_header, and NS_LOG_FUNCTION.

Referenced by ns3::Icmpv4L4Protocol::HandleTimeExceeded().

◆ GetInstanceTypeId()

TypeId ns3::Icmpv4TimeExceeded::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 456 of file icmpv4.cc.

References GetTypeId(), and NS_LOG_FUNCTION.

◆ GetSerializedSize()

uint32_t ns3::Icmpv4TimeExceeded::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 462 of file icmpv4.cc.

References ns3::Ipv4Header::GetSerializedSize(), m_header, and NS_LOG_FUNCTION.

◆ GetTypeId()

TypeId ns3::Icmpv4TimeExceeded::GetTypeId ( void )

static

Get ICMP type.

Returns: the ICMP type

Definition at line 404 of file icmpv4.cc.

References ns3::TypeId::SetParent().

Referenced by GetInstanceTypeId().

◆ Print()

void ns3::Icmpv4TimeExceeded::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

◆ Serialize()

void ns3::Icmpv4TimeExceeded::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.

◆ SetData()

void ns3::Icmpv4TimeExceeded::SetData ( Ptr< const Packet > data )

Get the ICMP carried data.

Parameters

data the data

◆ SetHeader()

void ns3::Icmpv4TimeExceeded::SetHeader ( Ipv4Header header )

Set the ICMP carried IPv4 header.

Parameters

header the header
