Abstract
The Singleton pattern describes a type that can only have one object constructed for it. That is, unlike other objects it should not be possible to obtain more than one instance within the same virtual machine. Thus the Singleton pattern ensures that only one instance of a class is created. All objects that use an instance of that type use the same instance.
