Functions

doFinalize

This template method is called at the end of finalize. By default it calls destroy(), but can be replaced by the derived class. This can be useful if it is not the Finalizable instance that awaits the finalize method.

finalize

This method is called (typically by this instance or its owner) to cleanup this instance while possibly first waiting for the finalizer promise to settle. Once settled, the doFinalize method is called.
