Detailed Description

The ResourceManager is the central Nepomuk configuration point.

Use the initialized() method to check the availabity of the Nepomuk system. Signals nepomukSystemStarted() and nepomukSystemStopped() can be used to enable or disable Nepomuk-specific GUI elements.

Member Function Documentation

void Nepomuk2::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 Nepomuk2::ResourceManager::generateUniqueUri

(

const QString &

label

)

Generates a unique URI that is not used in the store yet.

This method can 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

Definition at line 329 of file resourcemanager.cpp.

int Nepomuk2::ResourceManager::init

(

)

Initialize the Nepomuk framework.

This method will initialize the communication with the local Nepomuk-KDE services, ie. the data repository. It will trigger a reconnect to the Nepomuk database.

There is normally no reason to call this method manually except when using multiple threads. In that case it is highly recommended to call this method in the main thread before doing anything else.

Returns

0 if all necessary components could be found and -1 otherwise.

Definition at line 288 of file resourcemanager.cpp.

bool Nepomuk2::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.

Nepomuk2::ResourceManager * Nepomuk2::ResourceManager::instance ( )

static

Definition at line 270 of file resourcemanager.cpp.

Soprano::Model * Nepomuk2::ResourceManager::mainModel

(

)

Retrieve the main data storage model.

Definition at line 363 of file resourcemanager.cpp.

void Nepomuk2::ResourceManager::nepomukSystemStarted ( )

signal

Emitted once the Nepomuk system is up and can be used.

Warning

This signal will not be emitted if the Nepomuk system is running when the ResourceManager is created. Use initialized() to check the status.

Since

4.4

void Nepomuk2::ResourceManager::nepomukSystemStopped ( )

signal

Emitted once the Nepomuk system goes down.

Since

4.4

void Nepomuk2::ResourceManager::notifyError	(	const QString &	uri,
		int	errorCode
	)

Non-public API. Used by Resource to signalize errors.

Definition at line 322 of file resourcemanager.cpp.

void Nepomuk2::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.

Definition at line 316 of file resourcemanager.cpp.

void Nepomuk2::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 Nepomuk2::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

model

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

Since

4.1
