Detailed Description

Information element vector.

Introspection did not find any typical Config paths.

Implements a vector of WifiInformationElements. Information elements typically come in groups, and the WifiInformationElementVector class provides a representation of a series of IEs, and the facility for serialisation to and deserialisation from the over-the-air format.

No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 40 bytes (on a 64-bit architecture).

◆ GetInstanceTypeId()

TypeId ns3::WifiInformationElementVector::GetInstanceTypeId ( ) const

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.

◆ Print()

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

overridevirtual

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.

Definition at line 124 of file wifi-information-element-vector.cc.

◆ Serialize()

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

overridevirtual

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.
