Member Function Documentation

QList<const Property*> Nepomuk::Class::allProperties

(

)

const

const Property* Nepomuk::Class::findPropertyByLabel	(	const QString &	label,
		const QString &	language = QString()
	)		const

Search for a property in the class by its label.

Parameters

label	The label of the property (i.e. rdfs:label)
language	The language in which the label was specified. If empty the default rdfs:label is returned.

Returns

the Property object identified by label or 0 if the property could not be found.

const Property* Nepomuk::Class::findPropertyByName

(

const QString &

name

)

const

Search for a property in the class by its name.

Parameters

name	The name of the property.

Returns

the Property object identified by name or 0 if the property could not be found.

const Property* Nepomuk::Class::findPropertyByUri

(

const QUrl &

uri

)

const

Search for a property in the class by its name.

Parameters

uri	the URI of the property

Returns

the Property object identified by uri or 0 if the property could not be found.

bool Nepomuk::Class::isParentOf

(

const Class *

other

)

const

Check if a class inherits this class.

This is a recursive method which does not only check direct child classes.

Returns

true if other is derived from this class, false otherwise.

bool Nepomuk::Class::isSubClassOf

(

const Class *

other

)

const

Check if this class is derived from another class.

This is a recursive method which does not only check direct child classes.

Returns

true if this class is derived from other, false otherwise.

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

static

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

Dependancies are resolved automatically if possible.

Returns

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

Class& Nepomuk::Class::operator=

(

const Class &

)

QList<const Class*> Nepomuk::Class::parentClasses

(

)

const

Each class can have multiple parent classes.

Returns

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

QList<const Class*> Nepomuk::Class::subClasses

(

)

const

Returns

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