    1.23 +      \brief A CenRep interface for last used sync solutions
    1.24 +*
    1.25 +* \b  Purpose:
    1.26 +*
    1.27 +*	Calendar/contact data easily gets corrupted if a user is using several remote synchronization solutions at the same time. 
    1.28 +*         The purpose of this API is to provide the synchronization  solution vendors a way to 
    1.29 +*		- Indicate that they’re active synchronization solution for some  content type
    1.30 +*		- Detect that other synchronization solutions may be in use in the device.
    1.31 +*		.
    1.32 +* \b  API \b Description:
    1.33 +*
    1.34 +* 	Synchronizing content over several mechanisms from the device causes easily difficult problems, as the different protocols
    1.35 +*	 and systems are not aware of each other. 
    1.36 +*
    1.37 +*	For example, a synchronization solution using standard OMA DS technology is not aware of the
    1.38 + * 	simultaneous existence of some proprietary synchronization (aka. mobile PIM) solution,
    1.39 + * 	and vice versa. This is likely to cause problems, as the users may not be aware of the side
    1.40 + *	 effects that may occur from using several such solutions at the same time. Currently the
    1.41 + *	 problem is recognized by the vendors, and device applications do their best to warn user
    1.42 + * 	from using any other synchronization solution than the one being installed.
    1.43 + * 	
    1.44 + *	This API intends to enhance the warning mechanism in two ways:
    1.45 + *   		-  Provide the way for different solutions to know about each other, and
    1.46 + *		-  Offer a standard procedure how different solutions should behave when several solutions are used by the user
    1.47 + *		.
    1.48 + *	 This is achieved with a simple setting API utilizing Symbian OS Central Repository.
    1.49 + 
    1.50 + * \b Use \b cases:
    1.51 + *
    1.52 + * 	The use cases supported by this API are:
    1.53 + *  		-# Detect currently active synchronization solution
    1.54 +*			- When a synchronization solution is about to take some supported content type into use,
    1.55 + *        		 it should check whether there is some other Uid already present in the setting. If
    1.56 + *         		there isn’t, the solution should put it’s own Uid into the setting value. If there is
    1.57 + *        		 some unknown Uid, the setting should be aware that it’s changelog for that particular
    1.58 + *         		content may be out-of-date, and a full re-sync should be issued. It’s up to the solution
    1.59 + *        		 vendor to decide, whether the user should be notified about this. The user readable name
    1.60 + *         		of the active solution is readable using Symbian AppArc API method  \code RApaLsSession::GetAppInfo() \endcode
    1.61 +*			.
    1.62 +*		-# Activate a synchronization solution for certain content type
    1.63 + *		        - This use case allows the synchronization solution to register it’s Uid into the Central
    1.64 + *         		Repository. This information is used by other compliant solutions to find out the active
    1.65 + *         		solution for all supported content types
    1.66 +*			.			
    1.67 +*		.
    1.68 +*\b Using \b the \b Synchronization \b Capability \b API:
    1.69 + *  	-#  Detect currently active synchronization solution
    1.70 + *     		- Before activating itself as the active solution, the client of this API should check
    1.71 + *     		whether some other client has registered itself as the preferred solution for certain
    1.72 + *     		content type synchronization. An example of the check is:
    1.73 + *     		\code
    1.74 +*		CRepository* repository = CRepository::NewL( KCRUidSecon );
    1.75 + *     		TInt someSolutionInt; //Active solution UID
    1.76 + *     		// Get last used calendar sync solution..
    1.77 + *     		TInt ret = repository->Get( KSeconCalendarUid, someSolutionInt );
    1.78 + *     		TUid someSolutionUid = TUid::Uid(someSolutionInt)
    1.79 + *     		TUid mySolutionUid={0xf1f2f3f4}; //Application’s UID
    1.80 + *     		if(someSolutionUid != mySolutionUid)
    1.81 + *     		{
    1.82 + *         		...//Solution specific actions
    1.83 + *     		}		
    1.84 + *    		\endcode
    1.85 + *		.
    1.86 + *     		- If some other synchronization solution is active for the intended content type, the
    1.87 + *     		solution can still rewrite the old value, but it should note that a full resync may be
    1.88 + *     		needed in order to maintain system wide data consistency. It is up to the solution UI
    1.89 + *     		to decide, what kind of notification, if any, is given to the user.
    1.90 + *		.
    1.91 + *	-# Activate a solution for the content type
    1.92 + *     		- This use case is executed either during solution installation/commissioning, or at least
    1.93 + *     		before first synchronization. The activation is simple:	
    1.94 + *    		\code
    1.95 + *     		CRepository* repository = CRepository::NewL( KCRUidSecon );
    1.96 + *     		TUid mySolutionUid={0xf1f2f3f4}; //Application’s UID
    1.97 + *     		// Set mySolutionUid to last used calendar sync solution..
    1.98 + *     		TInt ret = repository->Set( KSeconCalendarUid, (TInt) mySolutionUid.iUid );
    1.99 + *		\endcode
   1.100 +*		.
   1.101 + *     		- Howto store also timestamp
   1.102 + *		\code
   1.103 + *     		// Timeformat is YYYYMMDDTHHMMSSZ (universal time),
   1.104 + *     		// where MM=1..12, DD=1..number of days in month, HH=0..23, MM=0..59, SS=0..59
   1.105 + *     		_LIT( KFormatDate, "%04d%02d%02dT%02d%02d%02dZ" );
   1.106 + *     		TTime timeNow;
   1.107 + *     		timeNow.UniversalTime(); // Store always universal time
   1.108 + *     		TDateTime now = timeNow.DateTime();
   1.109 + *     		TBuf<16> dateBuf;
   1.110 + *     		dateBuf.Format( KFormatDate, now.Year(), now.Month() + 1,
   1.111 + *     		now.Day() + 1, now.Hour(), now.Minute(), now.Second() );
   1.112 + *     		repository->Set( KSeconCalendarTime, dateBuf );
   1.113 + *     		\endcode
   1.114 + *		.
   1.115 + * 	-#  Error handling
   1.116 + *     		- As defined in the Central Repository API.
   1.117 + *		.
