Class NumericEntityIdValueImpl

java.lang.Object

org.wikidata.wdtk.datamodel.implementation.NumericEntityIdValueImpl

All Implemented Interfaces:

Serializable, EntityIdValue, IriIdentifiedValue, Value

Direct Known Subclasses:

ItemIdValueImpl, PropertyIdValueImpl

public abstract class NumericEntityIdValueImpl
extends Object
implements EntityIdValue, Serializable

Generic implementation of EntityIdValue that works with arbitrary Wikibase instances: it requires a baseIri that identifies the site globally.

TODO It would be cleaner to have an object that manages the site context instead of passing a base IRI string that is simply concatenated.

TODO For our common use case that Wikidata entities are processed, it might be useful to have a more lightweight object that does not store this known base IRI.
