The client’s message server session object can also call the interface whenever it completes a request to the Message Server. </p> <p>Session observers are important for run-time extensibility of the Messaging architecture, as message client applications can be informed of new <xref href="GUID-E96D8052-0CB2-53A6-915F-133D3058DCF9.dita">MTMs being registered</xref>. As the registry classes are session observers, they also can update their lists of the available MTM components, allowing new components to be loaded. </p> </li> <li id="GUID-32DAABF3-F9C0-5981-9795-49A4592124E8"><p>The <xref href="GUID-B36289AC-769F-3A83-BADB-AE0568E97581.dita"><apiname>MMsvEntryObserver</apiname></xref> class is notified when an individual entry changes, or when access to a message store has been successfully gained. Client objects that need to observe a session view must implement this interface. </p> </li> </ul> </conbody></concept> |
