public class SingletonConfigurator
extends BeanConfigurator

Specialized version of BeanConfigurator that will implement singleton getInstance() behavior with some advanced features. For normal createBean(), a single instance will be created the first time it is called and then returned again upon subsequent calls. For the createBean() that takes constructor arguments, the argument is used as a key into a singleton registry so that if the same arguments are passed again then the originally created object will be returned.
