Examples of org.osgi.service.device.Driver

org.osgi.service.device.Driver
A {@code Driver} service object must be registered by each Driver bundlewishing to attach to Device services provided by other drivers. For each newly discovered {@link Device} object, the device manager enters a biddingphase. The {@code Driver} object whose {@link #match(ServiceReference)}method bids the highest for a particular {@code Device} object will beinstructed by the device manager to attach to the {@code Device} object. @author $Id: db46dfadf76ffbc519a691834c80673acc90603f $ @see Device @see DriverLocator @ThreadSafe
