class SWACReceptacleInterface():
    """ This class provides a common interface to a switched AC power receptacle on an Extron product (extronlib.device). The user can instantiate the class directly or create a subclass to add, remove, or alter behavior for different types of devices.

    ---

    Arguments:
        - Host (extronlib.device) - handle to Extron device class that instantiated this interface class
        - Port (string) - port name (e.g. 'SAC1')
    
    ---
    
    Parameters:
        - CurrentChanged - Returns (float) - instantaneous current draw in Amperes
        - Host - Returns (extronlib.device) - handle to Extron device class that instantiated this interface class
        - Port - Returns (string) - port name
        - State - Returns (string) - current state of receptacle ('On', 'Off')
    
    ---
    
    Events:
        - CurrentChanged - (Event) triggers when the current draw changes. The callback takes two arguments. The first one is the SWACReceptacleInterface instance triggering the event, and the second is the current.
        - Offline - (Event) Triggers when port goes offline. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Offline').
        - Online - (Event) Triggers when port goes offline. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Online').
