NFEChangesKeeper (Oracle Spatial and Graph Java API Reference)

java.lang.Object
- oracle.spatial.network.nfe.model.edit.NFEChangesKeeper

```
public class NFEChangesKeeper
extends java.lang.Object
```
This class is meant to keep the references to the edited objects (network elements and features) in a project session, in order to keep the tracking of the changes performed and then save them into the DB when desired. The references kept belong to objects in the Model Manager (NFEModelManager), specifically to the network and featureLayers maps.
