Member Function Documentation
QList<Resource> Nepomuk::ResourceManager::allResources | ( | ) |
Retrieve a list of all resource managed by this manager.
- Since:
- 4.3
KDE_DEPRECATED QList<Resource> Nepomuk::ResourceManager::allResourcesOfType | ( | const QString & | type | ) |
QList<Resource> Nepomuk::ResourceManager::allResourcesOfType | ( | const QUrl & | type | ) |
Retrieve a list of all resources of the specified type.
This includes Resources that are not synced yet so it might not represent exactly the state as in the RDF store.
KDE_DEPRECATED QList<Resource> Nepomuk::ResourceManager::allResourcesWithProperty | ( | const QString & | uri, | |
const Variant & | v | |||
) |
- Deprecated:
- Use allResourcesWithProperty( const QString& type )
QList<Resource> Nepomuk::ResourceManager::allResourcesWithProperty | ( | const QUrl & | uri, | |
const Variant & | v | |||
) |
Retrieve a list of all resources that have property uri defined with a value of v.
This includes Resources that are not synced yet so it might not represent exactly the state as in the RDF store.
- Parameters:
-
uri The URI identifying the property. If this URI does not include a namespace the default namespace is prepended. v The value all returned resources should have set as properts uri.
static ResourceManager* Nepomuk::ResourceManager::createManagerForModel | ( | Soprano::Model * | model | ) | [static] |
Create a new ResourceManager instance which uses model as its override model.
This allows to use multiple instances of ResourceManager at the same time. Normally one does not need this method as the singleton accessed via instance() should be enough.
- Parameters:
-
model The model to read and write data from and to.
- Since:
- 4.3
KDE_DEPRECATED Resource Nepomuk::ResourceManager::createResourceFromUri | ( | const QString & | uri | ) |
- Deprecated:
- Use the Resource constructor directly.
Creates a Resource object representing the data referenced by uri. The result is the same as from using the Resource::Resource( const QString&, const QString& ) constructor with an empty type.
void Nepomuk::ResourceManager::deleteInstance | ( | ) |
In KDE 4.3 support for multiple ResourceManager instances has been introduced.
To keep binary compatibility both the constructor's and destructor's access visibility could not be changed. Thus, instead of deleting a custom ResourceManager instance the standard way, one has to call this method or use QObject::deleteLater.
- Since:
- 4.3
void Nepomuk::ResourceManager::error | ( | const QString & | uri, | |
int | errorCode | |||
) | [signal] |
Whenever a problem occurs (like for example failed resource syncing) this signal is emitted.
- Parameters:
-
uri The resource related to the error. errorCode The type of the error (Resource::ErrorCode)
QUrl Nepomuk::ResourceManager::generateUniqueUri | ( | const QString & | label | ) |
Generates a unique URI that is not used in the store yet.
This method ca be used to generate URIs for virtual types such as Tag.
- Parameters:
-
label A label that the algorithm should use to try to create a more readable URI.
- Returns:
- A new unique URI which can be used to define a new resource.
- Since:
- 4.2
KDE_DEPRECATED QString Nepomuk::ResourceManager::generateUniqueUri | ( | ) |
Generates a unique URI that is not used in the store yet. This method ca be used to generate URIs for virtual types such as Tag.
int Nepomuk::ResourceManager::init | ( | ) |
Initialize the Nepomuk framework.
This method will initialize the communication with the local Nepomuk-KDE services, ie. the data repository.
When using multiple threads make sure to call this method in the main thread before doing anything else.
- Returns:
- 0 if all necessary components could be found and -1 otherwise.
FIXME: introduce error codes and human readable translated error messages.
bool Nepomuk::ResourceManager::initialized | ( | ) | const |
- Returns:
- true if init() has been called successfully, ie. the KMetaData system is connected to the local RDF repository service and ready to work.
static ResourceManager* Nepomuk::ResourceManager::instance | ( | ) | [static] |
Soprano::Model* Nepomuk::ResourceManager::mainModel | ( | ) |
Retrieve the main data storage model.
void Nepomuk::ResourceManager::notifyError | ( | const QString & | uri, | |
int | errorCode | |||
) |
For internal use only.
Non-public API. Used by Resource to signalize errors.
void Nepomuk::ResourceManager::removeResource | ( | const QString & | uri | ) |
Remove the resource denoted by uri completely.
This method is just a wrapper around Resource::remove. The result is the same.
void Nepomuk::ResourceManager::resourceModified | ( | const QString & | uri | ) | [signal] |
This signal gets emitted whenever a Resource changes due to a sync procedure.
Be aware that modifying resources locally via the Resource::setProperty method does not result in a resourceModified signal being emitted.
- Parameters:
-
uri The URI of the modified resource.
NOT IMPLEMENTED YET
