[TYPO3-mvc] Abstract Classes and the DB

[Zalán Somogyváry]

Hello,

Thanks for the quick answer.

Hm. That means you have to break with the naming conventions... That's not very good ;( ... 
What's the matter if we use Concrete Table Inheritance? Is the naming issue the same?

My problem is that I have to make sure that every subclass has to implement a given method, but I can't use interfaces fpr that because there are other (gerneral) methods that are implemented in the abstract class. I have a scheme like this:

                        AbstractMediaItem
                             /                      \
            AbstractStream         AbstractFile
               /                                               \
      Video      Audio, etc.             Video, Audio, etc.

Is it possible to make a structure with more than one abstract instance like the one I described.

Regards,
Zalán
