ServiceReferenceInstance (org.qi4j.core.runtime 2.1 API)

java.lang.Object
- org.qi4j.runtime.service.ServiceReferenceInstance<T>

Type Parameters:
T - Service Type

All Implemented Interfaces:

org.qi4j.api.activation.Activation, org.qi4j.api.activation.ActivationEventListenerRegistration, org.qi4j.api.service.ServiceReference<T>, org.qi4j.api.structure.MetaInfoHolder, org.qi4j.api.type.HasTypes
```
public final class ServiceReferenceInstance<T>
extends Object
implements org.qi4j.api.service.ServiceReference<T>, org.qi4j.api.activation.Activation
```
Implementation of ServiceReference.
This manages the actual instance of the service and implements the service Activation.

Whenever the service is requested a proxy is returned which points to this class. This means that the instance can be passivated even though a client is holding on to a service proxy.
