Destructor.
If the notification is started, the destructor will cancel the notification.
| void | DoCancel | ( | ) | [private, virtual] |
Implements cancellation of an outstanding request.
This function is called as part of the active object's Cancel() .
It must call the appropriate cancel function offered by the active object's asynchronous service provider. The asynchronous service provider's cancel is expected to act immediately.
DoCancel() must not wait for event completion; this is handled by Cancel() .

Construct a triggering system settings change event notifier object.
When the object is constructed. The triggering system settings change notification request is not issued to the Location Triggering Server. Client shall call CLbtTriggeringSystemSettingsChangeEventNotifier::Start() to start notification.
| RLbt & aLbt | A referece to RLbt object. The subsession must be opened. Otherwise a panic is raised. |
| MLbtTriggeringSystemSettingsChangeEventObserver & aObserver | A referece to the observer object to receive triggering system setting change event. |
| TInt aPriority = CActive::EPriorityStandard | An integer specifying the priority of this active object. CActive::TPriority defines a standard set of priorities. |
| void | RunL | ( | ) | [private, virtual] |
Handles an active object's request completion event.
A derived class must provide an implementation to handle the completed request. If appropriate, it may issue another request.
The function is called by the active scheduler when a request completion event occurs, i.e. after the active scheduler's WaitForAnyRequest() function completes.
Before calling this active object's RunL() function, the active scheduler has:
1. decided that this is the highest priority active object with a completed request
2. marked this active object's request as complete (i.e. the request is no longer outstanding)
RunL() runs under a trap harness in the active scheduler. If it leaves, then the active scheduler calls RunError() to handle the leave.
Note that once the active scheduler's Start() function has been called, all user code is run under one of the program's active object's RunL() or RunError() functions.
CActiveScheduler::Start CActiveScheduler::Error CActiveScheduler::WaitForAnyRequest TRAPD
| IMPORT_C void | Start | ( | ) |
Start triggering system settings change event notification.
After this function is called, when triggering system settings are changed, the client will be notified from the observer interface.
Client shall call Cancel() function to stop the triggering system settings change event notification.
