Constructor & Destructor Documentation

Nepomuk::Tag::Tag

(

)

Create a new empty and invalid Tag instance.

Nepomuk::Tag::Tag

(

ResourceManager *

manager

)

Create a new empty and invalid Tag instance.

Parameters:

manager

The resource manager to use. This allows to mix resources from different managers and, thus, different models.

Since:

4.3

Nepomuk::Tag::Tag

(

const Tag &

)

Default copy constructor.

Nepomuk::Tag::Tag

(

const Resource &

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Nepomuk::Tag::Tag

(

const QString &

uriOrIdentifier

)

Create a new Tag instance representing the resource referenced by uriOrIdentifier.

Nepomuk::Tag::Tag	(	const QString &	uriOrIdentifier,
		ResourceManager *	manager
	)

Create a new Tag instance representing the resource referenced by uriOrIdentifier.

Parameters:

manager

The resource manager to use. This allows to mix resources from different managers and, thus, different models.

Since:

4.3

Nepomuk::Tag::Tag

(

const QUrl &

uri

)

Create a new Tag instance representing the resource referenced by uri.

Nepomuk::Tag::Tag	(	const QUrl &	uri,
		ResourceManager *	manager
	)

Create a new Tag instance representing the resource referenced by uri.

Parameters:

manager

The resource manager to use. This allows to mix resources from different managers and, thus, different models.

Since:

4.3

Nepomuk::Tag::~Tag

(

)

Destructor.

Nepomuk::Tag::Tag	(	const QString &	uri,
		const QUrl &	type
	)		[protected]

Nepomuk::Tag::Tag	(	const QUrl &	uri,
		const QUrl &	type
	)		[protected]

Nepomuk::Tag::Tag	(	const QString &	uri,
		const QUrl &	type,
		ResourceManager *	manager
	)		[protected]

Since:

4.3

Nepomuk::Tag::Tag	(	const QUrl &	uri,
		const QUrl &	type,
		ResourceManager *	manager
	)		[protected]

Member Function Documentation

static QList<Tag> Nepomuk::Tag::allTags

(

)

[static]

Retrieve a list of all available Tag resources.

This list consists of all resource of type Tag that are stored in the local Nepomuk meta data storage and any changes made locally. Be aware that in some cases this list can get very big.

In those cases it might be better to use the asyncronous approach via Query::QueryServiceClient and a Query::ResourceTypeTerm with type Soprano::Vocabulary::NAO::Tag().

Tag& Nepomuk::Tag::operator=

(

const Tag &

)

static QString Nepomuk::Tag::resourceTypeUri

(

)

[static]

Returns:

The URI of the resource type that is used in Tag instances.

QList<Resource> Nepomuk::Tag::tagOf

(

)

const

Get all resources that have this resource set as property 'Tag'.

Each Resource can be tagged with an arbitrary number of Tags. This allows a simple grouping of resources.
