Constructor & Destructor Documentation

◆ UanHeaderRcAck()

ns3::UanHeaderRcAck::UanHeaderRcAck ( )

Default constructor.

Definition at line 538 of file uan-header-rc.cc.

References m_frameNo.

Referenced by GetTypeId().

Here is the caller graph for this function:

◆ ~UanHeaderRcAck()

ns3::UanHeaderRcAck::~UanHeaderRcAck ( )

Member Function Documentation

◆ AddNackedFrame()

void ns3::UanHeaderRcAck::AddNackedFrame ( uint8_t frame )

NACK a frame.

Parameters

frame The data frame number being NACKed.

Definition at line 565 of file uan-header-rc.cc.

References m_nackedFrames.

Referenced by ns3::UanMacRcGw::EndCycle().

Here is the caller graph for this function:

◆ Deserialize()

uint32_t ns3::UanHeaderRcAck::Deserialize ( Buffer::Iterator start )

overridevirtual

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.

Here is the call graph for this function:

◆ GetFrameNo()

uint8_t ns3::UanHeaderRcAck::GetFrameNo ( ) const

Get the reservation frame number being ACKed.

Returns: The frame number.

References m_frameNo.

Referenced by ns3::UanMacRc::ProcessAck().

Here is the caller graph for this function:

◆ GetInstanceTypeId()

TypeId ns3::UanHeaderRcAck::GetInstanceTypeId ( ) const

overridevirtual

Get the most derived TypeId for this Object.

This method is provided by ns3::Object::GetInstanceTypeId but classes which derive from ns3::ObjectBase directly have to implement it themselves. Typically, this method should simply return the output of GetTypeId().

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

Implements ns3::ObjectBase.

Here is the call graph for this function:

◆ GetNackedFrames()

const std::set< uint8_t > & ns3::UanHeaderRcAck::GetNackedFrames ( ) const

Returns: The set of NACK'ed frames.

Here is the caller graph for this function:

◆ GetNoNacks()

uint8_t ns3::UanHeaderRcAck::GetNoNacks ( ) const

Get the number of data frames being NACKed.

Returns: The number of NACKed frames.

Definition at line 583 of file uan-header-rc.cc.

Referenced by GetSerializedSize(), Print(), ns3::UanMacRc::ProcessAck(), and Serialize().

Here is the caller graph for this function:

◆ GetSerializedSize()

uint32_t ns3::UanHeaderRcAck::GetSerializedSize ( ) const

overridevirtual

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.

Here is the caller graph for this function:

◆ Print()

void ns3::UanHeaderRcAck::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

Here is the call graph for this function:

◆ Serialize()

void ns3::UanHeaderRcAck::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.
