Finalizer

In object-oriented programming, a finalizer or finalize method is a special method that performs finalization, generally some form of cleanup. A finalizer is executed during object destruction, prior to the object being deallocated, and is complementary to an initializer, which is executed during object creation, following allocation. Finalizers are strongly discouraged by many, due to difficulty in proper use and the complexity they add, and alternatives are suggested instead, primarily the dispose pattern – see problems with finalizers.
