Member Function Documentation

__call__()

singleton.SingletonMeta.__call__	(		cls,
		*	args,
		**	kwargs )

Each time a class using this metaclass is instantiated, this method is called. It checks if an instance of the class already exists in the _instances dictionary:
- If no instance exists, it creates a new one by calling the superclass __call__, stores it in _instances, and returns it
- If an instance already exists, it returns the stored instance instead of creating a new one
