Rename 'navigator' to 'registration'

[Marijn Kruisselbrink, 2014/10/08 23:00:32]

argh, the danger of copy-paste coding... fixed.

+{
+    ServiceWorkerRegistrationGeofencing* supplement = static_cast<ServiceWorkerRegistrationGeofencing*>(HeapSupplement<ServiceWorkerRegistration>::from(navigator, supplementName()));
+    if (!supplement) {
+        supplement = new ServiceWorkerRegistrationGeofencing(&navigator);
+        provideTo(navigator, supplementName(), supplement);

+    return *supplement;
+}

+Geofencing* ServiceWorkerRegistrationGeofencing::geofencing(ServiceWorkerRegistration& navigator)

Ditto

[Marijn Kruisselbrink, 2014/10/08 23:00:32]

Done.
