Detailed Description

template<typename... Ts>
class ns3::TracedCallback< Ts >

Forward calls to a chain of Callback.

A TracedCallback has almost exactly the same API as a normal Callback but instead of forwarding calls to a single function (as a Callback normally does), it forwards calls to a chain of Callback. Connect adds a Callback at the end of the chain of callbacks. Disconnect removes a Callback from the chain of callbacks.

This is a functor: the chain of Callbacks is invoked by calling the operator() form with the appropriate number of arguments.

Template Parameters

Ts	[explicit] Types of the functor arguments.
