Method Detail

addRestrictedProperties

public static void addRestrictedProperties(java.util.Set<com.hp.hpl.jena.rdf.model.Property> properties,
                                           com.hp.hpl.jena.rdf.model.Resource ontClass)

addRestrictions

public static void addRestrictions(java.util.Set<com.hp.hpl.jena.rdf.model.Resource> restrictions,
                                   com.hp.hpl.jena.rdf.model.Resource ontClass)

findRestriction

public static com.hp.hpl.jena.rdf.model.Resource findRestriction(com.hp.hpl.jena.rdf.model.Resource ontClass,
                                                                 IRDFNodeFilter filter)

Starting at a given class, this method traverses the superclasses and equivalent classes until it finds an owl:Restriction that meets a given filter criteria. The method also looks into intersection classes. The traversal is breadth-first.

Parameters:

ontClass - the class to start traversal at

filter - the filter that can assess if a restriction meets the condition (this filter is only called with Restriction instances)

Returns:

the first restriction that passed the filter with true, or null

findRestriction
