|MSubDataStore (const QString &prefix, MDataStore &baseStore)|
|QString||prefix () const|
MSubDataStore takes another DataStore object and gives a limited view to it.
MSubDataStore doesn't store any data by itself but instead it uses another DataStore object for this. MSubDataStore offers a limited view to the keys of the underlying DataStore. It only allows access to keys with a given prefix. This can be seen as a namespace limitation. The prefix or namespace as well as the underlying DataStore object are given at construction time and they can't be changed after that.
Destructs the MSubDataStore.
Gets the prefix or namespace that was given to the class at construction time.
