Class JsonNullAwareDeserializer

java.lang.Object

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

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

com.fasterxml.jackson.databind.deser.std.JsonNodeDeserializer

com.github.fge.jsonpatch.JsonNullAwareDeserializer

All Implemented Interfaces:

Serializable

public final class JsonNullAwareDeserializer
extends JsonNodeDeserializer

Custom deserializer for JsonNode

Up to, and including, versions 2.1.4, Jackson's JsonNodeDeserializer deserializes a JSON null value as null. This custom deserializer deserializes it as a NullNode instead.
