| class MProtocolPresenceWatchingDataHost : public MXIMPBase |
Interface for managing cached subscribed presence information.
Interface is used by protocol adaptations to manage manage presentities presence information stored in XIMP Framework internal data cache.
This interface is implemented by XIMP Framework. Protocol adaptation can obtain reference to this interface from MXIMPProtocolConnectionHost interface.
For each separated protocol connection, protocol adaptation must use the specific MProtocolPresentityGroupsDataHost instance, what is received from the connection specific MXIMPProtocolConnectionHost instance.

Notifies XIMP Framework from subscribed presentitys presence information.
Protocol adaptation implementation can call this method to notify XIMP Framework from subscribed presentitys presence information. XIMP Framework updates its cached presentitys presence status, and notifies the subscribing clients from data changes.
XIMP Framework takes ownership of the argument(s), if method succeeds without a leave.
| MXIMPIdentity * aPresentityId | MXIMPIdentity object identifying the presentity of which subscribed presence information is delivered here. |
| MPresenceInfo * aPresenceInfo | MPresenceInfo object containing new presence information for the identified presentity. |
| const MXIMPDataSubscriptionState & | PresentityPresenceDataSubscriptionState | ( | const MXIMPIdentity & | aPresentityId | ) | const [pure virtual] |
Gets data subscription state for presentitys presence information.
Protocol adaptation can call this method to retrieve presentitys presence information data subscription state. Protocol adaptation can use data subscription state information, to optimize its own processing and network trafic amount.
| const MXIMPIdentity & aPresentityId |
| TXIMPRequestId | SetPresentityPresenceDataSubscriptionStateL | ( | MXIMPIdentity * | aPresentityId, |
| MXIMPDataSubscriptionState * | aSubscriptionState, | |||
| MXIMPStatus * | aStatus | |||
| ) | [pure virtual] | |||
Updates data subscription state for presentitys presence information.
Updates data subscription state for presentitys presence subscription. XIMP Framework calculates the subscription state change, from previous presentitys presence information content, and notifies the subscribing clients from data changes.
XIMP Framework takes ownership of the argument(s), if method succeeds without a leave.
| MXIMPIdentity * aPresentityId | MXIMPIdentity object identifying the presentity of which presence data subscription state is updated here. |
| MXIMPDataSubscriptionState * aSubscriptionState | New data subscription state for presentitys presence information. |
| MXIMPStatus * aStatus | Optional status object describing the the reason, why protocol adaptation updated data item subscription state. Given status object is passed to clients through data item specific data change event. NULL value is accepted. |
