static __new__(cls, *args, **kwargs)

Initializes a new instance of the ControllerBase.

The instance will be automatically added to the list of controllers to be cleaned up later. It guarantees that all the controller instances are followed up and cleaned up when the associate method ‘controllers_cleanup(cls)’ is called.

Note:

Do not override this method in subclasses to maintain this functionality.

Args:

*args: Suitable arguments passed to the constructor of the ControllerBase class. **kwargs: keywords passed to the constructor of the ControllerBase class.

Returns:

instance(ControllerBase): The new instance of the class that has been created.

classmethod controllers_cleanup()

Cleans up all controller instances.

It Calls the clean_up() method for each instance, since it iterates through the list of controllers to realize any needed cleanup which can fail so an error will be raised. Then, the remaining instances will continue processing.

Returns:

bool: True indicating that all the controllers are successfully cleaned up, otherwise False when an error occurred during the operation of the cleanup.
