Member Function Documentation

◆ Deserialize()

uint32_t ns3::HePpdu::HeSigHeader::Deserialize ( Buffer::Iterator  start)
overridevirtual
Parameters
startan 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.

◆ GetInstanceTypeId()

TypeId ns3::HePpdu::HeSigHeader::GetInstanceTypeId ( void  ) 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.

◆ GetMcs()

uint8_t ns3::HePpdu::HeSigHeader::GetMcs ( void  ) const

◆ GetSerializedSize()

uint32_t ns3::HePpdu::HeSigHeader::GetSerializedSize ( void  ) const
overridevirtual
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 350 of file he-ppdu.cc.

◆ GetTypeId()

TypeId ns3::HePpdu::HeSigHeader::GetTypeId ( void  )
static

Get the type ID.

Returns

◆ Print()

void ns3::HePpdu::HeSigHeader::Print ( std::ostream &  os) const
overridevirtual
Parameters
osoutput 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 339 of file he-ppdu.cc.

◆ Serialize()

void ns3::HePpdu::HeSigHeader::Serialize ( Buffer::Iterator  start) const
overridevirtual
Parameters
startan 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.
