Detailed Description
An active object class implemented by Symbian and used to subscribe for the updates in the Properties, retrieve the Properties and forward the notification to the client.
- Note
- Serialized part of the ECam implementation is assumed to define the Properties and publish them whenever there is change in the reserve status.
Constructor & Destructor Documentation
◆ ~CCameraStatusWatch()
| IMPORT_C CCameraStatusWatch::~CCameraStatusWatch | ( | ) |
Destructor.
The destructor has to be called by the client when it does not need the desired reserve notifications any more.
(generated from Symbian Developer Library)
Member Function Documentation
◆ NewL()
|
static |
Used to create the CCameraStatusWatch class object.
This is needed by the method TReservedInfo::SubscribeReserveInfoL in order to grab the reserve notification from the ECam implementation and hence further forward it to the observer MReserveObserver.
- Parameters
-
aReserveObserver Reference to an observer. aCameraIndex The camera index for which the subscription is needed. aSecureId The secure ID of the process where serialized part of the ECam implementation runs.
Leave condition: May leave with any error code
