public abstract class PropertyRestriction
The base class of all simple restrictions. Subclasses will implement the functionality for specific OWL or XSD restrictions. All restrictions are defined by a property and one ore more constraints and describe those individuals that are connected by the defined property to individuals under the condition that the defined constraint is fulfilled.

getRestrictionOnProperty(String propURI)
This method is specifically defined for working with property paths, hence whenever it is called it means that the path is already processed until the 'onProperty' of this Restriction and now we are interested in the restrictions defined for the next property in the path (the property given as input parameter). |
Object[] |
getUpperEnumeration()
Each type expression can contain multiple objects; this method returns this set of objects. |
protected Object |
matchesNonRestriction(TypeExpression subtype,
HashMap context,
int ttl,
List<MatchLogEntry> log)
Check all cases where the subtype is not a subclass of PropertyRestriction() . |
protected void |
setOnProperty(String propURI)
|
boolean |
setProperty(String propURI,
Object value)
Adds a statement with this resource as the subject, the given propURI as the predicate and the given value as the object. |

as the predicate and the given value as the object.
Subclasses must override this in order to decide if the statement to be
added fits the general class constraints. If not, the call of this method
should be ignored. For each property only one single call may be made to
this method, unless subsequent calls to this method for setting the value
of the same property are treated as an update for an update-able
property. Multi-valued properties must be set using an instance of
List
. The differentiation, if a such list should be
treated as an rdf:List, can be made with the help of
Resource.isClosedCollection(String)
. The default implementation here
accepts all property-value pairs blindly except for rdf:type which is
handled if the value is a type URI, a Resource or a java.util.List of
them.
Note: The setting of the property rdf:type is being handled by this class
via the final methods Resource.addType(String, boolean)
,
Resource.getType()
, and Resource.getTypes()
. Although these methods give
the view of handling type URIs as strings, but in reality the types are
stored as direct instances of this class. So, the subclasses should
ignore calls for setting rdf:type; if not, then the subclass must pay
attention that the value should be a List
of direct instances of
this class so that (1) the Resource.toString()
method returns just the
URI and (2) the serializers get no problems with the value. Also,
settings via subclasses may be overwritten by this class if a subsequent
call to Resource.addType(String, boolean)
is made.
