Overview

The Notifier provides a mechanism for broadcasting hooks during a simulation.

Hooks can be dispatched either to Procs or to Notifiable objects. They can register to a hook using the #subscribe method. Each invocation of this method registers the receiver to a given hook. Therefore, objects may register to several hooks.

A default Notifier instance is associated with Simulation instances so that objects can subscribe to simulation events.
