Example 1 with GpsLocation

use of joynr.types.Localisation.GpsLocation in project joynr by bmwcarit.

the class GpsConsumerApplication method run.

@Override
public void run() {
    DiscoveryQos discoveryQos = new DiscoveryQos();
    // As soon as the arbitration QoS is set on the proxy builder, discovery of suitable providers
    // is triggered. If the discovery process does not find matching providers within the
    // arbitration timeout duration it will be terminated and you will get an arbitration exception.
    discoveryQos.setDiscoveryTimeoutMs(10000);
    // Provider entries in the global capabilities directory are cached locally. Discovery will
    // consider entries in this cache valid if they are younger as the max age of cached
    // providers as defined in the QoS. All valid entries will be processed by the arbitrator when searching
    // for and arbitrating the "best" matching provider.
    // NOTE: Valid cache entries might prevent triggering a lookup in the global capabilities
    // directory. Therefore, not all providers registered with the global capabilities
    // directory might be taken into account during arbitration.
    discoveryQos.setCacheMaxAgeMs(Long.MAX_VALUE);
    // The discovery process outputs a list of matching providers. The arbitration strategy then
    // chooses one or more of them to be used by the proxy.
    discoveryQos.setArbitrationStrategy(ArbitrationStrategy.HighestPriority);
    // The provider will maintain at least a minimum interval idle time in milliseconds between
    // successive notifications, even if on-change notifications are enabled and the value changes more
    // often. This prevents the consumer from being flooded by updated values. The filtering happens on
    // the provider's side, thus also preventing excessive network traffic.

    // The provider will send notifications every maximum interval in milliseconds, even if the value didn't
    // change. It will send notifications more often if on-change notifications are enabled,
    // the value changes more often, and the minimum interval QoS does not prevent it. The maximum interval
    // can thus be seen as a sort of heart beat.

    // notifications (neither value notifications nor missed publication notifications) after

    // missed publication notification (depending on the value of the alert interval QoS).
