CumulativeDeltaModeler (Vitro API 1.14.2 API)

java.lang.Object
- org.apache.jena.rdf.listeners.StatementListener
- - edu.cornell.mannlib.vitro.webapp.dao.jena.CumulativeDeltaModeler

All Implemented Interfaces:

org.apache.jena.rdf.model.ModelChangedListener
```
public class CumulativeDeltaModeler
extends org.apache.jena.rdf.listeners.StatementListener
```
This ModelChangedListener will accumulate all statements added to or removed from the audited model in an additions model and a retractions model. Note that this class attempts to be clever. If a statement is retracted that is already in the additions model, the statement will be removed from the additions model and not added to the retractions model. in this object.
