		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 191 of file ndn-cs-tracer.cpp.

ns3::ndn::CsTracer::~CsTracer

(

void ns3::ndn::CsTracer::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	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

Definition at line 51 of file ndn-cs-tracer.cpp.

References Install().

void ns3::ndn::CsTracer::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)

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

void ns3::ndn::CsTracer::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)

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

References Install().

Ptr< CsTracer > ns3::ndn::CsTracer::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

Definition at line 162 of file ndn-cs-tracer.cpp.

void ns3::ndn::CsTracer::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 45 of file ndn-cs-tracer.cpp.

void ns3::ndn::CsTracer::PrintHeader

(

std::ostream &

os

)

const

Print head of the trace (e.g., for post-processing)

Parameters

os	reference to output stream

void ns3::ndn::CsTracer::Print

(

std::ostream &

os

)

const

Print current trace data.

Parameters

os	reference to output stream
