Interface DriverSelector
- public interface DriverSelector
When the device manager detects a new Device service, it calls all registered
Driver services to determine if anyone matches the Device service. If at least one
Driver service matches, the device manager must choose one. If there is a
Driver Selector service registered with the Framework, the
device manager will ask it to make the selection. If there is no
Driver Selector service, or if it returns an invalid result, or
throws an Exception, the device manager uses the default selection
strategy.
