Constructor & Destructor Documentation

◆ L3RateTracer() [1/2]

ns3::ndn::L3RateTracer::L3RateTracer	(	shared_ptr< std::ostream >	os,
		Ptr< Node >	node
	)

Trace constructor that attaches to the node using node pointer.

Parameters

os	reference to the output stream
node	pointer to the node

Definition at line 169 of file ndn-l3-rate-tracer.cpp.

◆ L3RateTracer() [2/2]

ns3::ndn::L3RateTracer::L3RateTracer	(	shared_ptr< std::ostream >	os,
		const std::string &	node
	)

Trace constructor that attaches to the node using node name.

Parameters

os	reference to the output stream
nodeName	name of the node registered using Names::Add

Definition at line 176 of file ndn-l3-rate-tracer.cpp.

◆ ~L3RateTracer()

ns3::ndn::L3RateTracer::~L3RateTracer ( )

virtual

Destructor.

Member Function Documentation

◆ InstallAll()

void ns3::ndn::L3RateTracer::InstallAll	(	const std::string &	file,
		Time	averagingPeriod = `Seconds(0.5)`
	)

static

Helper method to install tracers on all simulation nodes.

Parameters

file	File to which traces will be written. If filename is -, then std::out is used
averagingPeriod	Defines averaging period for the rate calculation, as well as how often data will be written into the trace file (default, every half second)

Definition at line 50 of file ndn-l3-rate-tracer.cpp.

References ns3::ndn::g_tracers, and Install().

◆ Install() [1/3]

void ns3::ndn::L3RateTracer::Install	(	const NodeContainer &	nodes,
		const std::string &	file,
		Time	averagingPeriod = `Seconds(0.5)`
	)

static

Helper method to install tracers on the selected simulation nodes.

Parameters

nodes	Nodes on which to install tracer
file	File to which traces will be written. If filename is -, then std::out is used
averagingPeriod	How often data will be written into the trace file (default, every half second)

Definition at line 84 of file ndn-l3-rate-tracer.cpp.

References ns3::ndn::g_tracers.

Referenced by Install(), and InstallAll().

◆ Install() [2/3]

void ns3::ndn::L3RateTracer::Install	(	Ptr< Node >	node,
		const std::string &	file,
		Time	averagingPeriod = `Seconds(0.5)`
	)

static

Helper method to install tracers on a specific simulation node.

Parameters

nodes	Nodes on which to install tracer
file	File to which traces will be written. If filename is -, then std::out is used
averagingPeriod	How often data will be written into the trace file (default, every half second)

Definition at line 122 of file ndn-l3-rate-tracer.cpp.

References ns3::ndn::g_tracers, and Install().

◆ Destroy()

void ns3::ndn::L3RateTracer::Destroy ( )

static

Explicit request to remove all statically created tracers.

This method can be helpful if simulation scenario contains several independent run, or if it is desired to do a postprocessing of the resulting data

Definition at line 44 of file ndn-l3-rate-tracer.cpp.

References ns3::ndn::g_tracers.

◆ Install() [3/3]

Ptr< L3RateTracer > ns3::ndn::L3RateTracer::Install	(	Ptr< Node >	node,
		shared_ptr< std::ostream >	outputStream,
		Time	averagingPeriod = `Seconds(0.5)`
	)

static

Helper method to install tracers on a specific simulation node.

Parameters

nodes	Nodes on which to install tracer
outputStream	Smart pointer to a stream
averagingPeriod	How often data will be written into the trace file (default, every half second)

Returns: a tuple of reference to output stream and list of tracers. !!! Attention !!! This tuple needs to be preserved for the lifetime of simulation, otherwise SEGFAULTs are inevitable
