class DigitalIOInterface():
    """ This class will provide a common interface for controlling and collecting data from Digital IO ports on Extron devices (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. 'DIO1')
        - (optional) Mode (string) - Possible modes are: 'DigitalInput' (default), and 'DigitalOutput'
        - (optional) Pullup (bool) - pull-up state on the port
    
    ---

    Parameters:
        - Host - Returns (extronlib.device) - handle to Extron device class that instantiated this interface class
        - Mode - Returns (string) - mode of the Digital IO port ('DigitalInput', 'DigitalOutput')
        - Port - Returns (string) - port name
        - Pullup - Returns (bool) - indicates if the Input port is being pulled up or not
        - State - Returns (string) - current state of Input port ('On', 'Off')
    
    ---

    Events:
        - 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 online. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Online').
        - StateChanged - (Event) Triggers when the input state changes. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('On' or 'Off').
