NavigatorContentServiceFactory (Eclipse Platform API Specification)

java.lang.Object
- org.eclipse.ui.navigator.NavigatorContentServiceFactory

```
public final class NavigatorContentServiceFactory
extends Object
```
Provides a factory pattern for creating INavigatorContentServices for given viewer ids.
Clients may supply the viewer in createContentService(String, StructuredViewer) or wait until the content provider is created by the service and set on the viewer. When the content provider is set, the viewer will call inputChanged(), and the content service will update its managed viewer accordingly. Therefore, each content service should be attached to at most one viewer.
