ConnectionService (Northfield ASP)

All Superinterfaces:

ConnectionSession
```
public interface ConnectionService
extends ConnectionSession
```
The ConnectionService provides User programs with access to configured and operational ASP services such as the optimizer service. User programs can only access the ASP Service APIs from this interfaces. This component wraps the complexity of the underlying service provider objects that perform service instantiation and configuration. It also handles license management, remote connections, and inter service integrations, should they be required.
