Member Function Documentation

QList<Resource> Nepomuk::ResourceManager::allResourcesOfType

(

const QString &

type

)

Deprecated:

Use 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.

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.

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.

Returns:

The Resource representing the data at uri or an invalid Resource object if the local NEPOMUK RDF store does not contain an object with URI uri.

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)

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
	)

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

void Nepomuk::ResourceManager::setOverrideMainModel

(

Soprano::Model *

model

)

Override the main model used for all storage.

By default the main model used is the Nepomuk server main model.

Parameters:

The

model to use instead of the Nepomuk server or 0 to reset.

Since:

4.1
