Example 1 with DeviceTaskException

use of org.onosproject.provider.general.device.impl.DeviceTaskExecutor.DeviceTaskException in project onos by opennetworkinglab.

the class GeneralDeviceProvider method handleConnectionSetup.

private void handleConnectionSetup(DeviceId deviceId) {
    assertConfig(deviceId);
    // Bind pipeconf (if any and if device is capable).
    bindPipeconfIfRequired(deviceId);
    // Get handshaker.
    final DeviceHandshaker handshaker = handshakerOrFail(deviceId);
    if (handshaker.hasConnection() || handshakersWithListeners.containsKey(deviceId)) {
        throw new DeviceTaskException("connection already exists");
    }
    // Add device agent listener.
    handshakersWithListeners.put(deviceId, handshaker);
    handshaker.addDeviceAgentListener(id(), deviceAgentListener);
    // Start connection via handshaker.
    if (!handshaker.connect()) {
        // Failed! Remove listeners.
        handshaker.removeDeviceAgentListener(id());
        handshakersWithListeners.remove(deviceId);
        // Clean up connection state leftovers.
        handshaker.disconnect();
        throw new DeviceTaskException("connection failed");
    }
    createOrUpdateDevice(deviceId, false);
// From here we expect a CHANNEL_OPEN event to update availability.

Example 2 with DeviceTaskException
