Class AsArrayTypeDeserializer

  • All Implemented Interfaces:
    java.io.Serializable
    Direct Known Subclasses:
    AsExternalTypeDeserializer, AsPropertyTypeDeserializer

    public class AsArrayTypeDeserializer
    extends TypeDeserializerBase
    implements java.io.Serializable
    Type deserializer used with JsonTypeInfo.As.WRAPPER_ARRAY inclusion mechanism. Simple since JSON structure used is always the same, regardless of structure used for actual value: wrapping is done using a 2-element JSON Array where type id is the first element, and actual object data as second element.

      • forProperty

        public TypeDeserializer forProperty​(BeanProperty prop)
        Description copied from class: TypeDeserializer
        Method called to create contextual version, to be used for values of given property. This may be the type itself (as is the case for bean properties), or values contained (for Collection or Map valued properties).

        forProperty in class TypeDeserializerBase
      • 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.

        Method called when actual object is serialized as JSON Array.

                                                    throws java.io.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).

        Throws:
        java.io.IOException

                                                 throws java.io.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).
        Specified by:
        deserializeTypedFromAny in class TypeDeserializer
        Throws:
        java.io.IOException
