The cardinality of this property as specified by nrl:cardinality.

Returns

the cardinality of the property or -1 if none was set.

const Class* Nepomuk::Property::domain

(

)

const

The domain of the property.

const Property* Nepomuk::Property::inverseProperty

(

)

const

The inverse property (nrl:inverseProperty).

Returns

A Property instance representing the inverse property of this one or 0 if none was specified in the ontology.

Literal Nepomuk::Property::literalRangeType

static const Property* Nepomuk::Property::load ( const QUrl &  uri )

static

Loads a property actually including the whole ontology it is declared in.

Dependancies are resolved automatically if possible.

Returns

A property object representing the property identified by uri or an invalid Property object if the resource identified by uri is either not a property or does not exist.

int Nepomuk::Property::maxCardinality

(

)

const

The maximum cardinality of this property as specified by nrl:maxCardinality.

Returns

the maximum cardinality of the property or -1 if none was set.

int Nepomuk::Property::minCardinality

(

)

const

Returns

the minimum cardinality of the property or -1 if none was set.

Property& Nepomuk::Property::operator=

(

const Property &

)

QList<const Property*> Nepomuk::Property::parentOf

(

)

const

Returns

A list of all properties that have this property as a parent. Be aware that this list can never be final since other ontologies that have not been loaded yet may contain properties that are derived from this property.

QList<const Property*> Nepomuk::Property::parentProperties

(

)

const

Each property can have multiple parent properties.

Returns

A list of all parent properties of this property. If the list is emppty it means that the property has no direct parents, i.e. it is derived from rdf:Resource.

const Class* Nepomuk::Property::range

(

)

const
