An <code><a class="el" href="interface_observer.html">Observer</a></code> is an object that encapsulates information about an interested object with a method that should be called when a particular <code><a class="el" href="protocol_i_notification-p.html">INotification</a></code> is broadcast. <p>
In PureMVC, the <code><a class="el" href="interface_observer.html">Observer</a></code> class assumes these responsibilities: <ul>
