GraphChangeWithBaseGraph

 ObservableGraph baseGraph)

Method Details

getBaseGraph

public ObservableGraph getBaseGraph()

createSetField

public org.aksw.commons.collection.observable.ObservableCollection<org.apache.jena.graph.Node> createSetField(org.apache.jena.graph.Node sourceNode,
 org.aksw.jenax.arq.util.triple.TripleFilter dftp)

createValueField

public org.aksw.commons.collection.observable.ObservableValue<org.apache.jena.graph.Node> createValueField(org.apache.jena.graph.Node sourceNode,
 org.aksw.jenax.arq.util.triple.TripleFilter dftp)

getSameAsInferredGraphView

public org.apache.jena.graph.Graph getSameAsInferredGraphView()

Return a graph view where all attributes of resources that are renamed to the same final resource appear on all involved resources. This graph view differs from the effective graph view where the resources that are the source of renaming do no longer exist (as they have been renamed)

Returns:

refreshDeletions

protected void refreshDeletions()

createSetForPredicate

public org.aksw.commons.collection.observable.ObservableCollection<org.apache.jena.graph.Node> createSetForPredicate(org.apache.jena.graph.Node source,
 org.apache.jena.graph.Node predicate,
 boolean isForward)

Return a set view over the values of a given predicate. Adding items to the set creates new triples. TODO Maybe the result should not be an ObservableSet directly but a GraphNode that supports the set view and e.g. a triple based view
