Class AsWrapperTypeDeserializer

  • All Implemented Interfaces:
    Serializable

    public class AsWrapperTypeDeserializer
    extends TypeDeserializerBase
    implements Serializable
    Type deserializer used with JsonTypeInfo.As.WRAPPER_OBJECT inclusion mechanism. Simple since JSON structure used is always the same, regardless of structure used for actual value: wrapping is done using a single-element JSON Object where type id is the key, and actual object data as the value.

      • getTypeInclusion

        public com.fasterxml.jackson.annotation.JsonTypeInfo.As getTypeInclusion()
        Description copied from class: TypeDeserializer
        Accessor for type information inclusion method that deserializer uses; indicates how type information is (expected to be) embedded in JSON input.

      • deserializeTypedFromArray

        public Object deserializeTypedFromArray​(com.fasterxml.jackson.core.JsonParser jp,
                                                DeserializationContext ctxt)
                                         throws IOException
        Description copied from class: TypeDeserializer
        Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Array (regardless of Java type). Method needs to figure out intended polymorphic type, locate JsonDeserializer to use, and call it with JSON data to deserializer (which does not contain type information).

        Throws:
        IOException
      • deserializeTypedFromScalar

        public Object deserializeTypedFromScalar​(com.fasterxml.jackson.core.JsonParser jp,
                                                 DeserializationContext ctxt)
                                          throws IOException
        Description copied from class: TypeDeserializer
        Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as a scalar JSON value (something other than Array or Object), regardless of Java type. Method needs to figure out intended polymorphic type, locate JsonDeserializer to use, and call it with JSON data to deserializer (which does not contain type information).

        IOException
      • deserializeTypedFromAny

        public Object deserializeTypedFromAny​(com.fasterxml.jackson.core.JsonParser jp,
                                              DeserializationContext ctxt)
                                       throws IOException
        Description copied from class: TypeDeserializer
        Method called to let this type deserializer handle deserialization of "typed" object, when value itself may have been serialized using any kind of JSON value (Array, Object, scalar). Should only be called if JSON serialization is polymorphic (not Java type); for example when using JSON node representation, or "untyped" Java object (which may be Map, Collection, wrapper/primitive etc).

        IOException
      • _deserialize

        protected Object _deserialize​(com.fasterxml.jackson.core.JsonParser p,
                                      DeserializationContext ctxt)
                               throws IOException
        Method that handles type information wrapper, locates actual subtype deserializer to use, and calls it to do actual deserialization.
        Throws:
        IOException
