Method Documentation
| __init__ | ( | self ) |
Default constructor. Creates an empty Property.
| __init__ | ( | self, | ||
| Nepomuk.Property | a0 | |||
| ) |
Default copy constructor
| int cardinality | ( | self ) |
The cardinality of this property as specified by nrl:cardinality.
- Returns:
- the cardinality of the property or -1 if none was set.
| Nepomuk.Class domain | ( | self ) |
The domain of the property.
| Nepomuk.Property inverseProperty | ( | self ) |
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.
| Nepomuk.Literal literalRangeType | ( | self ) |
If the rage of this property is a literal (i.e. range returns 0) this method provides the literal type.
- Returns:
- the literal type of this property or an empty, invalid Literal if the range is a Class.
\sa range
| Nepomuk.Property load | ( | QUrl | uri | |
| ) |
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 maxCardinality | ( | self ) |
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 minCardinality | ( | self ) |
The minimum cardinality of this property as specified by nrl:minCardinality.
- Returns:
- the minimum cardinality of the property or -1 if none was set.
| [const Propert] parentOf | ( | self ) |
- 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.
| [const Propert] parentProperties | ( | self ) |
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.
| Nepomuk.Class range | ( | self ) |
The range of the property.
- Returns:
- The range of the property or an invalid Class in case the range of this poperty is a literal.
