| class CDmDomainManager : public CActive |
An abstract class to allow a domain controller to interface to the domain manager.
To make use of this class an application must derive from it and implement a RunL() method to handle notifications. After the derived class has been instantiated, it must call ConstructL() .

Constructor.
Adds this active object to the active scheduler.

Destructor.
Closes the session to the domain manager.

| IMPORT_C void | ConstructL | ( | ) | [protected] |
The second-phase constructor.
This function attempts to connect to the hierarchy specified in the constructor.
| IMPORT_C TInt | GetTransitionFailureCount | ( | ) |
Gets the number of transition failures since the last transition request.
| IMPORT_C TInt | GetTransitionFailures | ( | RArray < const TTransitionFailure > & | aTransitionFailures | ) |
Requests a list of transition failures since the last transition request.
| RArray < const TTransitionFailure > & aTransitionFailures | A client-supplied array of TTransitionFailure objects which on exit will contain the failures that have occurred since the last transition request. |

| TDmTraverseDirection | aDirection | |||
| ) | ||||
Requests a system-wide state transition.
The domain hierarchy is traversed in the specified direction
| TDmDomainState aState | The target state. |
| TDmTraverseDirection aDirection | The direction in which to traverse the hierarchy. |
| void | RunL | ( | ) | [pure 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.
