Instance Method Details

#instantiate ⇒ Object

Takes the definition data that was given when the instantiator was created and treats it as the path to and name of the class to instantiate. This class is then instantiated and returned. This requires that the class have a no-argument constructor.

If the class includes the Singleton module, then the singleton instance of the class will be returned.
