All callbacks from XIMP Framework XIMP context to client direction happen through this interface HandlePresenceContextEvent() method. Data content in callbacks is presented to client with following event specific interfaces:

• MXIMPRequestCompleteEvent

• MXIMPContextStateEvent

• MOwnPresenceEvent

• MPresentityPresenceEvent

• MPresentityGroupListEvent

• MPresentityGroupContentEvent

• MPresenceWatcherListEvent

• MPresenceGrantRequestListEvent

• MPresenceBlockListEvent

Client can dispatch and cast event types on its own event callback implementation in following way:

        void CMyObserverClass::HandlePresenceContextEvent(
      const MXIMPContext& aContext,
      const MXIMPBase& aEvent )
      {
      switch( aEvent.GetInterfaceId() )
          {
          case MXIMPRequestCompleteEvent::KInterfaceId:
              {
              const MXIMPRequestCompleteEvent* complEvent =
                  TXIMPGetInterface< const MXIMPRequestCompleteEvent >::From( aEvent,
                                                                              MXIMPBase::EPanicIfUnknown );

              // Do here request complete event specific handling
              complEvent->RequestId();

              break;
              }


          case MXIMPContextStateEvent::KInterfaceId:
              {
              const MXIMPContextStateEvent* ctxtStateEvent =
                  TXIMPGetInterface< const MXIMPContextStateEvent >::From( aEvent,
                                                                                   MXIMPBase::EPanicIfUnknown );
              // Do here context state event specific handling
              ctxtStateEvent->ContextState();

              break;
              }


          default:
              {
              // New event types may be introduced in newer XIMP Framework
              // versions, so handle unknown event types gracefully.
              break;
              }
          }
      }
