how to delete singleton object

Question

Assuming this implementation of a singleton pattern ( of course we should avoid Singleton: it is just question), I have just been thinking about static object being created.

Answer 1

Part of the Singleton design pattern is that it is indestructible.

EDIT:

There are 2 varieties of singletons with respect to destructibility:

1. Destructible (They die when the application does)
2. Indestructible (They die when the machine does)

Either way, if built properly, once the singleton instance is created, it stays. This one of the major criticisms of the Singleton design pattern.

Here are a few references that address the destructibility aspect of the pattern.
