A store for labels, descriptions and other metadata of classes and properties.

Values are retrieved from a DataSource and cached.

getCachedLabel()

Literal getCachedLabel	(	String	iri,
		boolean	preferPlural
	)

Returns a label, only taking into account previously cached values, without querying the data sources.

Fast.

Parameters

iri	IRI of the resource whose label to return
preferPlural	Return conf:pluralLabel if available

Returns

The best label found, or null if none

getWeight()

int getWeight	(	Property	property,
		boolean	forInverse
	)

Returns the conf:weight of the property.

The inverse's weight can be requested; if no inverse weight is specified then the "forward" weight is used.

Parameters

property	The property whose weight to return
forInverse	If true, look for the inverse's weight first

Returns

The conf:weight assigned to the property

                                                                    {

                if (result == null) result = weights.get(property.getURI());
                return result == null ? 0 : result.intValue();
