Usually one does not need an abstract class in ruby, if you are
thinking along the lines of C++ or Java. Reason for this is that
ruby is not strictly typed so any class with a conforming interface
can be used where that interface is expected. This is the concept
of 'duck-typing'.

Could you describe your situation in more detail?
