csl::Model Class Reference

The Model/Observable/Subject class; instances of its subclasses should send themselves, this->changed(some_data); on "relevant" state changes; the code they inherit (from Model) manages updating the list of observer/dependent objects in that they each receive update(some_data); and can access the model-passed data (the model might pass "this").

Detailed Description

The Model/Observable/Subject class; instances of its subclasses should send themselves, this->changed(some_data); on "relevant" state changes; the code they inherit (from Model) manages updating the list of observer/dependent objects in that they each receive update(some_data); and can access the model-passed data (the model might pass "this").

Note the addition of timers, so observers can request no more than a certain rate of updates.
