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.

Member Function Documentation

NewL ( MReserveObserver &, TInt, TInt )

CCameraStatusWatch *	NewL	(	MReserveObserver &	aReserveObserver,
			TInt	aCameraIndex,
			TInt	aSecureId
		)	[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.

leave: May leave with any error code

Parameter	Description
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.
