Class JacksonValueDeserializer

java.lang.Object

com.fasterxml.jackson.databind.JsonDeserializer<T>

com.fasterxml.jackson.databind.deser.std.StdDeserializer<JacksonValue>

org.wikidata.wdtk.datamodel.json.jackson.datavalues.JacksonValueDeserializer

All Implemented Interfaces:

Serializable

public class JacksonValueDeserializer
extends com.fasterxml.jackson.databind.deser.std.StdDeserializer<JacksonValue>

Custom Jackson deserializer that maps the JSON representation of Wikibase values to WDTK classes. In most cases, the class to use is defined by the value of the "type" field, but for entities one has to look deeper into the structure to get the "entity-type" field as well. This is not possible using simpler mechanisms.
