Detailed Description

This class is designed to probe an underlying ns3 TraceSource exporting a packet.

This probe exports a trace source "Output" with argument of type Ptr<const Packet>. This probe exports another trace source "OutputBytes" with arguments of type uint32_t, which is the number of bytes in the packet. The trace sources emit values when either the probed trace source emits a new value, or when SetValue () is called.
