Member Function Documentation

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

virtual

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 written. This method is thus expected to call Buffer::Iterator::Prev prio to actually reading any data.

Implements ns3::Trailer.

TypeId ns3::WifiMacTrailer::GetInstanceTypeId ( void  ) const

virtual

Returns

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

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

Implements ns3::ObjectBase.

uint32_t ns3::WifiMacTrailer::GetSerializedSize ( void  ) const

virtual

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.

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

virtual

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.

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

virtual

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.
