Abstract Singleton Class?

807603Jan 31 2008 — edited Jan 31 2008

hi all
i have an abstract class and i want to extend it such that it becomes a singleton. However i wish i can also gain the benefits of abstraction so that i can reference the abstract class whatever the concrete class that extends it
so how can i write the "getInstance()" method in both the abstract and concrete classes knowing that i can't create an abstract static method?!
thanks in advance
