Constructor & Destructor Documentation

Ontology() [1/3]

Nepomuk::Types::Ontology::Ontology

(

)

Default constructor.

Creates an empty Ontology.

Ontology() [2/3]

Nepomuk::Types::Ontology::Ontology

(

const QUrl &

uri

)

Create the ontology referred to by uri.

The result is either a valid ontology which could be loaded from the Nepomuk store or a simple class which only contains the uri.

Be aware that the data is only loaded once read.

Subsequent calls result in a simple hash lookup of cached data.

Ontology() [3/3]

Nepomuk::Types::Ontology::Ontology

(

const Ontology &

)

Default copy constructor.

~Ontology()

Nepomuk::Types::Ontology::~Ontology

(

)

Destructor.

Member Function Documentation

allClasses()

QList< Class > Nepomuk::Types::Ontology::allClasses

(

)

All classes defined in this ontology, i.e.

its namespace.

allProperties()

QList< Property > Nepomuk::Types::Ontology::allProperties

(

)

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()

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

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 an invalid one if the class could not be found.

findClassByName()

Class Nepomuk::Types::Ontology::findClassByName

(

const QString &

name

)

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 an invalid one if the class could not be found.

findPropertyByLabel()

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

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 an invalid one if the property could not be found.

findPropertyByName()

Property Nepomuk::Types::Ontology::findPropertyByName

(

const QString &

name

)

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 an invalid one if the property could not be found.

operator=()

Ontology & Nepomuk::Types::Ontology::operator=
