class RApaLsSession : public RSessionBase

/** A session with the application architecture server.

The server provides access to a cached list of the applications on the device. 

To use this class, clients first need to connect to the server. 

Then, one of GetAllApps(), GetEmbeddableApps() or GetFilteredApps() needs to be called. 

These functions do some initialisation of server data in preparation for returning the 

application list (which is owned by the server).

Then, GetNextApp() is called in a loop. The first time around, it populates the session's 

application list and retrieves the first application in the list. Further calls to GetNextApp() 

retrieve the remaining applications in the list, until RApaLsSession::ENoMoreAppsInList is 

returned.

The session should be closed when it is no longer needed, before it goes out of scope.

Various functions in RApaLsSession need to access the application list, and may return 

RApaLsSession::EAppListInvalid to indicate that the function was called before the initial 

population of the list is complete. If this occurs, you could try again after a short delay.

This class provides many other functions, for instance launching applications, querying 

application-specific information, recognising data.
