Class DatamodelConverter

org.wikidata.wdtk.datamodel.helpers.DatamodelConverter

All Implemented Interfaces:

SnakVisitor<Snak>, ValueVisitor<Value>

public class DatamodelConverter
extends Object
implements SnakVisitor<Snak>, ValueVisitor<Value>

Class to re-create data model objects using a specified factory. This is provided in place of having copy constructors in each and every implementation of the data model. Note that data model objects are usually immutable and do not need to be copied. The use of this class is to convert data objects to a specific implementation, as might be needed for some specialized purpose (e.g., for JSON export).

visit

public Value visit(EntityIdValue value)

Description copied from interface: ValueVisitor

Visits a EntityIdValue and returns a result. In practice, only specific subtypes of EntityIdValue are used, such as ItemIdValue and PropertyIdValue. Since the set of possible subtypes can be extended by extensions of Wikibase, the visitor only visits the general (abstract) supertype. Implementations will have to decide if the given specific type is supported and what to do with it.

value - the value to visit

Returns:

the result for this value
