Member Function Documentation

DeserializeInformationField()

uint16_t ns3::AddbaExtension::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

start	an iterator which points to where the information should be written.
length	the expected number of bytes to read

Returns

the number of bytes read

ElementId()

WifiInformationElementId ns3::AddbaExtension::ElementId ( ) const

overridevirtual

Get the wifi information element ID.

Returns

the wifi information element ID

Implements ns3::WifiInformationElement.

Definition at line 32 of file addba-extension.cc.

References IE_ADDBA_EXTENSION.

GetInformationFieldSize()

uint16_t ns3::AddbaExtension::GetInformationFieldSize ( ) const

overrideprivatevirtual

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

Implements ns3::WifiInformationElement.

Definition at line 38 of file addba-extension.cc.

Print()

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

overridevirtual

Generate human-readable form of IE.

Parameters

os	output stream

Reimplemented from ns3::WifiInformationElement.

SerializeInformationField()

void ns3::AddbaExtension::SerializeInformationField ( Buffer::Iterator  start ) const

overrideprivatevirtual

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

Parameters

start

an iterator which points to where the information should be written.
