◆ DeserializeInformationField()

uint16_t TestWifiSubElement::DeserializeInformationField ( Buffer::Iterator start,
uint16_t length )
overrideprivatevirtual

Deserialize information (i.e., the body of the IE, not including the Element ID and length octets)

Parameters
startan iterator which points to where the information should be written.
lengththe expected number of bytes to read
Returns
the number of bytes read

Implements ns3::WifiInformationElement.

◆ ElementId()

WifiInformationElementId TestWifiSubElement::ElementId ( ) const
overridevirtual

Get the wifi information element ID.

Returns
the wifi information element ID

◆ GetInformationFieldSize()

uint16_t TestWifiSubElement::GetInformationFieldSize ( ) const

Length of serialized information (i.e., the length of the body of the IE, not including the Element ID and length octets.

This is the value that will appear in the second octet of the entire IE - the length field - if the IE is not fragmented)

Returns
the length of serialized information

Serialize information (i.e., the body of the IE, not including the Element ID and length octets)

Parameters
startan iterator which points to where the information should be written.
