Detailed Description

template<typename Derived, typename... Elems>
class ns3::WifiMgtHeader< Derived, std::tuple< Elems... > >

Base class for implementing management frame headers.

This class adopts the CRTP idiom, mainly to allow subclasses to specialize the method used to initialize Information Elements before deserialization (InitForDeserialization).

The sorted list of Information Elements that can be included in the management frame implemented as a subclass of this class is provided as the template parameter pack. Specifically:

the type of a mandatory Information Element IE is IE
the type of an optional Information Element IE is std::optional<IE>
the type of an Information Element IE that can appear zero or more times is std::vector<IE>

Template Parameters

Derived	[explicit] the type of derived management frame
Elems	[explicit] sorted list of Information Elements that can be included in mgt frame

◆ Deserialize()

template<typename Derived , typename... Elems>

uint32_t ns3::WifiMgtHeader< Derived, std::tuple< Elems... > >::Deserialize ( Buffer::Iterator start )

finalvirtual

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.

◆ Print()

template<typename Derived , typename... Elems>

void ns3::WifiMgtHeader< Derived, std::tuple< Elems... > >::Print ( std::ostream & os ) const

finalvirtual

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.
