Detailed Description

an application which sends one ICMP ECHO request, waits for a REPLYs and reports the calculated RTT.

Note: The RTT calculated is reported through a trace source.

Member Function Documentation

void ns3::V4Ping::DoDispose ( void )

privatevirtual

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.
