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.
