Interface ServiceBus.CallInjector

All Known Implementing Classes:

ServiceBusImpl.CallInjectorImpl

Enclosing interface:

ServiceBus

public static interface ServiceBus.CallInjector

The call injector allows to directly call a service with a ServiceCall. There is no matchmaking done and the callee needs to be known. This is not the normal way of invoking a service; normally, a ServiceRequest should be sent. This interface is separated from the rest of the bus to have a different shared object and, thus, to allow for low-level security. In OSGi terms, this would be a separate OSGi service that the application needs to have permissions to use.
