void Nepomuk2::ResourceData::determineUri

(

)

Searches for the resource in the Nepomuk store using m_kickoffId and m_kickoffUri.

This will either get the actual resource URI from the database and add m_data into ResourceManagerPrivate::m_initializedData or it will find another ResourceData instance in m_initializedData which represents the same resource. The ResourceData that should be used is set in all the associated resources.

Definition at line 580 of file resourcedata.cpp.

bool Nepomuk2::ResourceData::exists

(

)

This method only works with a proper URI, i.e.

it does not work on non-initialized resources that only know their kickoffUriOrId

void Nepomuk2::ResourceData::remove

(

bool

recursive = true

)

Remove this resource data from the store completely.

Parameters

recursive

If true all statements that contain this resource as an object will be removed, too.

Will reset this instance to 0 as if constructed without parameters Used by remove() and deleteData()

void Nepomuk2::ResourceData::setProperty	(	const QUrl &	uri,
		const Variant &	value
	)

Set a property.

The property will directly be saved to the RDF store. Calls store to make sure this resource and property resources are properly stored.

Definition at line 389 of file resourcedata.cpp.

void Nepomuk2::ResourceData::setWatchEnabled

(

bool

status

)

Definition at line 815 of file resourcedata.cpp.

bool Nepomuk2::ResourceData::store

(

)

Makes sure the resource is present in the RDF store.

This means that if it does not exist the type and the identifier (if one has been used to create the instance) are stored.

This is also the only place where a new URI is generated via ResourceManager::generateUniqueUri() in case m_uri is empty.

exists, setProperty

Definition at line 259 of file resourcedata.cpp.

QUrl Nepomuk2::ResourceData::type

(

)

Returns

The main type of the resource. ResourceData tries hard to make this the most important type, i.e. that which is furthest down the hierachy.

Definition at line 128 of file resourcedata.cpp.

void Nepomuk2::ResourceData::updateKickOffLists	(	const QUrl &	uri,
		const Variant &	oldvariant,
		const Variant &	newvariant
	)

Updates ResourceManagerPrivate's list.

Definition at line 741 of file resourcedata.cpp.

QUrl Nepomuk2::ResourceData::uri

(

)

const

The URI of the resource.

This might be empty if the resource was not synced yet.
