@CheckForNull <ServiceType> ServiceType getService(@Nonnull Class<ServiceType> serviceType)
If multiple such services exist, the service with the highest ranking (as specified in its Constants.SERVICE_RANKING property) is returned. If there is a tie in ranking, the service with the lowest service ID (as specified in its Constants.SERVICE_ID property); that is, the service that was registered first is returned.
This is equal to the semantics from BundleContext.getServiceReference(Class).
ServiceType
- The type (interface) of the service.serviceType
- The type (interface) of the service.null
if no services are registered which implement the specified class.@CheckForNull <ServiceType> ServiceType[] getServices(@Nonnull Class<ServiceType> serviceType, String filter)
The returned array is sorted descending by service ranking (i.e. the service with the highest ranking is returned first). If there is a tie in ranking, the service with the lowest service ID (as specified in its Constants.SERVICE_ID property); that is, the service that was registered first is returned first.

- The type (interface) of the service.serviceType
- The type (interface) of the service.filter
