Member Function Documentation

allClasses()

QList< const Class * > Nepomuk::Ontology::allClasses

(

)

const

All classes defined in this ontology, i.e.

its namespace.

allProperties()

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

(

)

const

A list of all properties defined in this ontology.

This does not include properties that use classes of this ontology but are defined in a different one.

findClassByLabel()

const Class * Nepomuk::Ontology::findClassByLabel	(	const QString &	label,
		const QString &	language = QString() ) const

Search for a class in the ontology by its label.

Parameters

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

Returns

the Class object identified by label or 0 if the class could not be found.

findClassByName()

const Class * Nepomuk::Ontology::findClassByName

(

const QString &

name

)

const

Search for a class in the ontology by its name.

Parameters

name	The name of the class.

Returns

the Class object identified by name or 0 if the class could not be found.

findClassByUri()

const Class * Nepomuk::Ontology::findClassByUri

(

const QUrl &

uri

)

const

Search for a class in the ontology by its name.

Parameters

uri	the URI of the class

Returns

the Class object identified by uri or 0 if the class could not be found.

findPropertyByLabel()

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

Search for a property in the ontology 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.

findPropertyByName()

const Property * Nepomuk::Ontology::findPropertyByName

(

const QString &

name

)

const

Search for a property in the ontology 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.

findPropertyByUri()

const Property * Nepomuk::Ontology::findPropertyByUri

(

const QUrl &

uri

)

const

Search for a property in the ontology 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.

load()

const Ontology * Nepomuk::Ontology::load ( const QUrl & uri )

static

Loads an ontology.

Dependancies are resolved automatically if possible.

Returns

An Ontology object representing the ontology identified by uri or an invalid Ontology object if the resource identified by uri is either not an ontology or does not exist.

operator=()

Ontology & Nepomuk::Ontology::operator=

(

const Ontology &

)

uri()

QUrl Nepomuk::Ontology::uri

(

)

const

The URI of the ontology, i.e.

its namespace
