Propagator< TI > Class Template Reference

#include "lib/time/control-impl.hpp"

Description

template<class TI>
class lib::time::mutation::Propagator< TI >

Implementation building block: propagate changes to listeners.

The Propagator manages a set of callback signals, allowing to propagate notifications for changed Time values.

There are no specific requirements on the acceptable listeners, besides exposing a function-call operator to feed the changed time value to. Both Mutator and Propagator employ one primary template parameter, which is the type of the time values to be fed in and propagated.
