Detailed Description

Information element vector

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.

This type is not accessible from the Config system.
No Attributes are defined for this type.
No TraceSources are defined for this type.

Attention: When you use RemoveHeader, WifiInformationElementVector supposes, that all buffer consists of information elements

Parameters

virtual

Needed when you try to deserialize a lonely IE inside other header.

Parameters

start is the start of the buffer

Returns: deserialized bytes

Here is the caller graph for this function:

TypeId ns3::WifiInformationElementVector::GetInstanceTypeId ( ) const

virtual

Returns: the TypeId associated to the most-derived type of this instance.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

Implements ns3::ObjectBase.

Here is the call graph for this function:

uint32_t ns3::WifiInformationElementVector::GetSerializedSize ( ) const

virtual

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.

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

virtual

Parameters

os output stream This method is used by Packet::Print to print the content of a trailer as ascii data to a c++ output stream. Although the trailer 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 103 of file wifi-information-element-vector.cc.

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

virtual

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.

void ns3::WifiInformationElementVector::SetMaxSize ( uint16_t size )

Set maximum size to control overflow of the max packet length.
