Examples with Driver org.osgi.service.device.Driver used on opensource projects

Example 1 with Driver

use of org.osgi.service.device.Driver in project felix by apache.

the class DeviceManagerTest method DriverRemoved.

/**
 * does not really test anything special, but ensures that the internal
 * structure is able to parse the addition/ removal
 * @throws Exception
 */
@Test
public void DriverRemoved() throws Exception {
    Driver driver = tstCreateDriver("org.apache.felix.driver-1.0", 1);
    ServiceReference ref = m_osgi.getReference(driver);
    m_manager.driverAdded(ref, driver);
    m_manager.driverRemoved(ref);
}

Example 2 with Driver

use of org.osgi.service.device.Driver in project felix by apache.

the class DeviceManagerTest method DriverAdded.

/**
 * does not really test anything special, but ensures that the internal
 * structure is able to parse the addition
 * @throws Exception
 */
@Test
public void DriverAdded() throws Exception {
    Driver driver = tstCreateDriver("org.apache.felix.driver-1.0", 1);
    m_manager.driverAdded(m_osgi.getReference(driver), driver);
}

Example 3 with Driver

use of org.osgi.service.device.Driver in project felix by apache.

the class DeviceManagerTest method DeviceAddedNoDriverLocatorSuccessfulAttach.

/**
 * 	We add a device, but there are no driver locators, however, there is a driver
 *  that matches. Thus an attach must follow.
 * @throws Exception
 */
@Test
public void DeviceAddedNoDriverLocatorSuccessfulAttach() throws Exception {

    Driver driver = tstCreateDriver("org.apache.felix.driver-1.0", 1);
    CountDownLatch attachLatch = tstExpectAttach(driver, device);
    m_manager.driverAdded(m_osgi.getReference(driver), driver);

    if (!attachLatch.await(5, TimeUnit.SECONDS)) {
        Assert.fail("expected attach");
    }
}

Example 4 with Driver

use of org.osgi.service.device.Driver in project felix by apache.

the class DeviceManagerTest method tstExpectDriverLocatorFor.

/**
 * This method generates behavior on the provided DriverLocator.
 *
 * The given driver Ids and their matches are expected as drivers found
 * by this driver locator.
 * Also, if a driver is found, we can also expect that loadDriver is called;
 * resulting in an InputStream. That particular input stream should, when installed
 * using a bundle context, lead to the registration of a driver with
 * the correcsponding driver id.
 *
 * @param locator
 * @param driverIds
 * @param matches
 * @return
 * @throws Exception

Example 5 with Driver

use of org.osgi.service.device.Driver in project felix by apache.

the class DeviceManagerTest method DeviceAddedNoDriverLocatorAttachFails.

/**
 * 	We add a device, but there are no driver locators, however, there is a driver
