ns3::FlowProbe Class Reference

The FlowProbe class is responsible for listening for packet events in a specific point of the simulated space, report those events to the global FlowMonitor, and collect its own flow statistics regarding only the packets that pass through that probe. More...

void ns3::FlowProbe::DoDispose ( void  )
protectedvirtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Object.

Reimplemented in ns3::Ipv6FlowProbe, and ns3::Ipv4FlowProbe.

FlowProbe::Stats ns3::FlowProbe::GetStats ( ) const

Get the partial flow statistics stored in this probe.

With this information you can, for example, find out what is the delay from the first probe to this one.

Returns
the partial flow statistics
