Member Function Documentation

◆ Deserialize()

uint32_t ns3::WifiMacTrailer::Deserialize ( Buffer::Iterator end )

overridevirtual

Parameters

end	an iterator which points to the end of the buffer where the trailer should be read from.

Returns: the number of bytes read.

This method is used by Packet::RemoveTrailer to re-create a trailer from the byte buffer of a packet. The data read is expected to match bit-for-bit the representation of this trailer in real networks. The input iterator points to the end of the area where the data shall be read from. This method is thus expected to call Buffer::Iterator::Prev prior to actually reading any data.

Implements ns3::Trailer.

References ns3::WIFI_MAC_FCS_LENGTH.

◆ GetInstanceTypeId()

TypeId ns3::WifiMacTrailer::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.

◆ GetSerializedSize()

uint32_t ns3::WifiMacTrailer::GetSerializedSize ( ) const

overridevirtual

Returns: the expected size of the trailer.

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

◆ Print()

void ns3::WifiMacTrailer::Print ( std::ostream & os ) const

overridevirtual

Parameters

os output stream This method is used by Packet::Print to print the content of a trailer as ascii data to a c++ output stream. Although the trailer 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::Trailer.

Definition at line 41 of file wifi-mac-trailer.cc.

◆ Serialize()

void ns3::WifiMacTrailer::Serialize ( Buffer::Iterator start ) const

overridevirtual

Parameters

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

This method is used by Packet::AddTrailer 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 trailer in real networks. The input iterator points to the end of the area where the data shall be written. This method is thus expected to call Buffer::Iterator::Prev prior to actually writing any data.
