 class="block">Calls the observer method, passing the given event context.
 <p>
 The container should always call this method, but the default implementation delegates to <a href="#notify(T)"><code>notify(Object)</code></a>.
 <p>
 The implementation of this method for a custom observer method is responsible for deciding whether to call the method if
 the <a href="#getReception()"><code>getReception()</code></a> returns <a href="../../event/Reception.html#IF_EXISTS"><code>Reception.IF_EXISTS</code></a>.</div
