Enhancement: AbstractDeviceFactory can "register" devices #131

Closed EAGrahamJr closed 1 year ago

EAGrahamJr commented 1 year ago

There are several methods used with the DeviceStates internal class to determine whether or not devices are "opened" or not (isDeviceOpened, deviceOpened, deviceClosed).

deviceClosed is actually invoked by the AbstractDevice. However, there is no "automatic" (or semi-automatic) means to utilized the other two associated functions.

This issue is to track the addition of a method to the AbstractDeviceFactory for implementations to easily track device open/close.

I see this is actually managed in sub-classes of this factory - closing.

np - this internal aspect has evolved a bit over the years - doing my best to provide a completely seamless user experience and handle all of the device cleanup stuff.
