CMtmUiDataRegistry Class Reference
| class CMtmUiDataRegistry : public CObserverRegistry |
Accesses the UI Data MTM registry.
This registry holds details of the all the UI Data MTMs currently available on the system. Message client applications use this class to get a CBaseMtmUiData-derived object by which to access UI Data MTM functionality.
Note that the base class CMtmDllRegistry provides functions for discovering what MTMs are present in the registry.

Member Functions Documentation
NewL(CMsvSession &, TTimeIntervalMicroSeconds32)
Gets a CMtmUiDataRegistry object.
The client should delete this object when it is no longer required.
The registry keeps a reference count of the number of instances of each MTM in use. When that reference count falls to zero, the DLL that provides the MTM is unloaded. However, this is not done immediately, but only after the time specified in aTimeoutMicroSeconds32. This increases efficiency in cases where the DLL is required again shortly.

NewMtmL(const RLibrary &, CRegisteredMtmDll &)
NewMtmUiDataLayerL(const TUid &)
Creates a UI Data MTM object for the MTM specified by aMtmTypeUid.
The client should delete the returned object when it is no longer required.
