Examples of org.qi4j.api.service.ServiceReference

org.qi4j.api.service.ServiceReference
From a ServiceReference you can access and modify metadata about a service. You can also access the actual service through get(), that can then be invoked.

    Map<Type, ServiceReference> serviceReferences = new ConcurrentHashMap<Type, ServiceReference>();
    Map<Type, Iterable<ServiceReference>> servicesReferences = new ConcurrentHashMap<Type, Iterable<ServiceReference>>();


    public <T> ServiceReference<T> findService( final Class<T> serviceType )
    {
        ServiceReference serviceReference = serviceReferences.get( serviceType );
        if( serviceReference == null )
        {
            serviceReference = Iterables.first( findServices( serviceType ));
            if( serviceReference != null )
            {
