<h1><a name="kanchor7"></a>Events</h1>
<p>Often you need more information about the replication process or even need to intervene it. dRS allows the registration of a event listener in order to perform such tasks.</p>
<p>When you create the replication session you can pass such a listener instance. The listener will be called for each object which is replicated. </p>
