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').
