I have absolutely no idea, as nobody else has either. We have not
discussed this issue. I am just certain that it will be considered
insane to allow applications raw access to hardware - it's just
completely opposite to all aims of Java's abstraction and inherent
security features. System components must have access to devices, but
they will be JOS specific, and could thus implement an interface for
informing them when a device has changed status. Something like this:
package jos.system.device;
public interface DeviceListener extends EventListener {
public void deviceConnected(Device device);
public void deviceDisconnected(Device device);
public void deviceStatusChanged(Device device, String name,
Object newvalue);
}
