Method Detail

visit

public org.json.JSONObject visit(DatatypeIdValue value)

Description copied from interface: ValueVisitor

Visits a DatatypeIdValue and returns a result. This type of value does not occur in snaks, so some implementation will not need this method.

Specified by:

visit in interface ValueVisitor<org.json.JSONObject>

Parameters:

value - the value to visit

Returns:

the result for this value

visit

public org.json.JSONObject 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.

Specified by:

visit in interface ValueVisitor<org.json.JSONObject>

Parameters:

value - the value to visit

Returns:

the result for this value

visit

public org.json.JSONObject visit(GlobeCoordinatesValue value)

Description copied from interface: ValueVisitor

Visits a GlobeCoordinatesValue and returns a result.

Specified by:

visit in interface ValueVisitor<org.json.JSONObject>

Parameters:

Returns:

the result for this value

visit

public org.json.JSONObject visit(MonolingualTextValue value)
