Constructor Detail

RelationshipChecker

public RelationshipChecker(org.apache.jena.ontology.OntModel ontModel)

Method Detail

anyUrisInCommon

public boolean anyUrisInCommon(List<String> list1,
                               List<String> list2)

Are there any URIs that appear in both of these lists?

isResourceOfType

public boolean isResourceOfType(String resourceUri,
                                String typeUri)

Is this resource a member of this type? That is, is there an statement of the form: <resourceUri> rdfs:type <typeUri>

getObjectsOfProperty

public List<String> getObjectsOfProperty(String resourceUri,
                                         String propertyUri)

Get a list of the object URIs that satisfy this statement: <resourceUri> <propertyUri> <objectUri> May return an empty list, but never returns null.

getObjectsOfLinkedProperty

public List<String> getObjectsOfLinkedProperty(String resourceUri,
                                               String linkUri,
                                               String propertyUri)

Get a list of the object URIs that satisfy these statements: <resourceUri> <linkUri> <contextNodeUri> <contextNodeUri> <propertyUri> <objectUri> May return an empty list, but never returns null.

getObjectsThroughLinkingNode

public List<String> getObjectsThroughLinkingNode(String resourceUri,
                                                 String property1Uri,
                                                 String linkNodeTypeUri,
                                                 String property2Uri)

Get a list of URIs for object that link to the specified resource, by means of the specified properties, through a linking node of the specified type. So we're looking for object URIs that statisfy these statements: <resourceUri> <property1Uri> <linkNodeUri> <linkNodeUri> rdfs:type <linkNodeTypeUri> <linkNodeUri> <property2Uri> <objectUri>

createSelector

public org.apache.jena.rdf.model.Selector createSelector(String subjectUri,
                                                         String predicateUri,
                                                         String objectUri)

createSelector

public org.apache.jena.rdf.model.Selector createSelector(org.apache.jena.rdf.model.Resource subject,
                                                         String predicateUri,
                                                         String objectUri)

authorizedDecision

protected PolicyDecision authorizedDecision(String message)

An AUTHORIZED decision with a message like "PolicyClass: message".
