Peter:
The function I'm calling isn't implemented. I found it in the source code:
public class RestRelationshipIndex extends RestIndex<Relationship>
implements RelationshipIndex {
public RestRelationshipIndex( RestRequest restRequest, String
indexName, RestAPI restApi ) {
super( restRequest, indexName, restApi );
}
public Class<Relationship> getEntityType() {
return Relationship.class;
}
public org.neo4j.graphdb.index.IndexHits<Relationship> get( String s,
Object o, Node node, Node node1 ) {
throw new UnsupportedOperationException();
}
public org.neo4j.graphdb.index.IndexHits<Relationship> query( String s,
Object o, Node node, Node node1 ) {
throw new UnsupportedOperationException();
}
public org.neo4j.graphdb.index.IndexHits<Relationship> query( Object o,
Node node, Node node1 ) {
throw new UnsupportedOperationException();
}
@Override
public boolean isWriteable() {
return true;
}
}
