Method Detail

delete

public static void delete(com.hp.hpl.jena.rdf.model.Resource subject,
                          com.hp.hpl.jena.rdf.model.Property predicate,
                          com.hp.hpl.jena.rdf.model.RDFNode object)

delete

public static void delete(com.hp.hpl.jena.ontology.OntModel ontModel,
                          com.hp.hpl.jena.graph.Node subject,
                          com.hp.hpl.jena.graph.Node predicate,
                          com.hp.hpl.jena.graph.Node object)

Deletes a given triple from the model. This method is needed because Jena does not correctly delete triples if they are from a sub-Graph.

Parameters:

ontModel - the OntModel to delete from

subject - the subject Node

predicate - the predicate Node

object - the object Node

deleteAll

public static void deleteAll(com.hp.hpl.jena.rdf.model.Resource resource)

deleteAll

public static void deleteAll(java.util.Iterator resources)

deleteOperand

public static void deleteOperand(com.hp.hpl.jena.ontology.UnionClass unionClass,
                                 com.hp.hpl.jena.rdf.model.Resource operand)

isDeletable

public static boolean isDeletable(java.util.Collection resources)

isDeletableReference

public static boolean isDeletableReference(com.hp.hpl.jena.rdf.model.Resource resource)

Checks if a given resource is only directly used in triples stored in read/write graphs. This can be used to quickly detect whether a given resource can be renamed etc.

Parameters:

resource - the resource to test

Returns:

true if all triples using resource can be deleted

isDeletable

public static boolean isDeletable(java.util.Iterator resources)

Checks if a collection of resources can be deleted from this model. A resource is deletable if all depending Statements are deletable.

Parameters:

resources - the resources to delete

Returns:

true if the resources can be deleted
