Detailed Description
Abstract base class for Class and Property;.
Base class for static ontology entities Class and Property. It encapsulates the generic labels and comments that both types have.
Due to internal optimizations comparing two Entities is much faster than comparing two QUrl objects.

QString Nepomuk::Types::Entity::comment | ( | const QString & | language = KGlobal::locale() ->language() | ) |
Retrieve the comment of the entity (rdfs:comment)
- Parameters
-
language The code of the language to use. Defaults to the session language configured in KDE. As of KDE 4.3 only the currently configured language is loaded to save memory.
- Returns
- The comment translated into
language
or the default fallback comment if no translation is available or an empty string if no comment could be found at all.
QString Nepomuk::Types::Entity::comment | ( | const QString & | language = KGlobal::locale() ->language() | ) | const |
Retrieve the comment of the entity (rdfs:comment)
- Parameters
-
language The code of the language to use. Defaults to the session language configured in KDE. As of KDE 4.3 only the currently configured language is loaded to save memory.
- Returns
- The comment translated into
language
or the default fallback comment if no translation is available or an empty string if no comment could be found at all.
Const version
- Since
- 4.4
QIcon Nepomuk::Types::Entity::icon | ( | ) |
Retrieve the icon stored for the entity (nao:hasSymbol)
If no symbol is defined for the entity a null icon will be returned.
- Since
- 4.1
QIcon Nepomuk::Types::Entity::icon | ( | ) | const |
Retrieve the icon stored for the entity (nao:hasSymbol)
If no symbol is defined for the entity a null icon will be returned.
Const version.
- Since
- 4.4
bool Nepomuk::Types::Entity::isAvailable | ( | ) |
bool Nepomuk::Types::Entity::isAvailable | ( | ) | const |
bool Nepomuk::Types::Entity::isValid | ( | ) | const |
Is this a valid Entity, i.e.
has it a valid URI. A valid Entity does not necessarily have a label and a comment, it does not even have to exist in the Nepomuk store.

- isAvailable
QString Nepomuk::Types::Entity::label | ( | const QString & | language = KGlobal::locale() ->language() | ) |
Retrieve the label of the entity (rdfs:label)
- Parameters
-
language The code of the language to use. Defaults to the session language configured in KDE. As of KDE 4.3 only the currently configured language is loaded to save memory.
- Returns
- The label translated into
language
or the default fallback label if no translation is available or the name() if no label could be found at all.
QString Nepomuk::Types::Entity::label | ( | const QString & | language = KGlobal::locale() ->language() | ) | const |
Retrieve the label of the entity (rdfs:label)
- Parameters
-
language The code of the language to use. Defaults to the session language configured in KDE. As of KDE 4.3 only the currently configured language is loaded to save memory.
- Returns
- The label translated into
language
or the default fallback label if no translation is available or the name() if no label could be found at all.
Const version
- Since
- 4.4
QString Nepomuk::Types::Entity::name | ( | ) | const |
The name of the resource.
The name equals the fragment of the URI.
|
inline |
bool Nepomuk::Types::Entity::operator!= | ( | const Entity & | other | ) | const |
Compares two Entity instances.
This is faster than simply comparing the URIs.
bool Nepomuk::Types::Entity::operator!= | ( | const QUrl & | other | ) | const |
Compares the Entity with a URI.
- Since
- 4.5
bool Nepomuk::Types::Entity::operator== | ( | const Entity & | other | ) | const |
Compares two Entity instances.
This is faster than simply comparing the URIs.
bool Nepomuk::Types::Entity::operator== | ( | const QUrl & | other | ) | const |
Compares the Entity with a URI.
- Since
- 4.5
void Nepomuk::Types::Entity::reset | ( | bool | recursive = false | ) |
The Types classes are optimized for performance under the aasumption that ontologies never change during the execution time of an application.
Since there might be situations where this does not apply the internal cache can be reset via this method.
- Parameters
-
recursive If true
all related entities will be reset as well.
- Since
- 4.1
QUrl Nepomuk::Types::Entity::uri | ( | ) | const |
The URI of the resource.
bool Nepomuk::Types::Entity::userVisible | ( | ) | const |
nao:userVisible can be used to hide certain properties and resources of a certain type from the user.
- Returns
true
if this entity should be visible to the user.
- Since
- 4.6
