Review Comment:
I can do this but I don't like the way the code ends up looking like: since
we are talking about a TableDataManager and not a BaseTableDataManager, I will
still have to cast TableDataManager to BaseTableDataManager before I invoke the
method. (Note the hierarchy is as follows
TableDataManager->BaseTableDataManager->RealTimeTableDataManager) As an
alternative I can bring these interfaces up to TableDataManager and override in
BaseDataManager as nop function and then with the implementation I need in
RealTimeTableDataManager. This has the problem that we start exposing low level
interfaces in what should be the high level TableDataManager. So I think it is
best to leave the code as is.
