KDE 4.9 PyKDE API Reference
Entity Class Reference
from PyKDE4.nepomuk import *
Subclasses: Nepomuk.Types.Class, Nepomuk.Types.Ontology, Nepomuk.Types.Property
Namespace: Nepomuk.Types
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.

Method Documentation
| __init__ | ( | self, | ||
| Nepomuk.Types.Entity | a0 | |||
| ) |
Create an invalid Entity instance.
| __init__ | ( | self ) |
Create an invalid Entity instance.
| QString comment | ( | self, | ||
| QString | 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.
Const version
- Since:
- 4.4
| QIcon icon | ( | self ) |
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 isAvailable | ( | self ) |
Is this Entity available locally, i.e. could its properties be loaded from the Nepomuk store.
Const version.
- Since:
- 4.4
| bool isValid | ( | self ) |
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.
\sa isAvailable
| QString label | ( | self, | ||
| QString | 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.
Const version
- Since:
- 4.4
| QString name | ( | self ) |
The name of the resource. The name equals the fragment of the URI.
| bool operator != | ( | self, | ||
| Nepomuk.Types.Entity | other | |||
| ) |
Compares the Entity with a URI.
- Since:
- 4.5
| bool operator != | ( | self, | ||
| QUrl | other | |||
| ) |
Compares the Entity with a URI.
- Since:
- 4.5
| bool operator == | ( | self, | ||
| Nepomuk.Types.Entity | other | |||
| ) |
Compares the Entity with a URI.
- Since:
- 4.5
| bool operator == | ( | self, | ||
| QUrl | other | |||
| ) |
Compares the Entity with a URI.
- Since:
- 4.5
| reset | ( | self, | ||
| bool | recursive=0 | |||
| ) |
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 uri | ( | self ) |
The URI of the resource
| bool userVisible | ( | self ) |
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
