Examples of org.osgi.service.device.DriverLocator

org.osgi.service.device.DriverLocator
A Driver Locator service can find and load device driver bundles given a property set. Each driver is represented by a unique {@code DRIVER_ID}.
Driver Locator services provide the mechanism for dynamically downloading new device driver bundles into an OSGi environment. They are supplied by providers and encapsulate all provider-specific details related to the location and acquisition of driver bundles. @author $Id: fdbe1a5d8957dcd47445d1c421e439a8c8dfceec $ @see Driver @ThreadSafe

        // Populate matches with driver locator recommendations

        if (dla != null) {
            for (int i = 0; i < dla.length; i++) {
                try {
                    DriverLocator dl = dla[i];
                    String[] dria = dl.findDrivers(props);
