## Class AsWrapperTypeDeserializer

- java.lang.Object
- - com.fasterxml.jackson.databind.jsontype.TypeDeserializer
  - - com.fasterxml.jackson.databind.jsontype.impl.TypeDeserializerBase
    - - com.fasterxml.jackson.databind.jsontype.impl.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.

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `Object` | `deserializeTypedFromAny(com.fasterxml.jackson.core.JsonParser jp, DeserializationContext ctxt)` 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).
    `Object` | `deserializeTypedFromArray(com.fasterxml.jackson.core.JsonParser jp, DeserializationContext ctxt)` Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Array (regardless of Java type).
    `Object` | `deserializeTypedFromObject(com.fasterxml.jackson.core.JsonParser jp, DeserializationContext ctxt)` Deserializing type id enclosed using WRAPPER_OBJECT style is straightforward
    `Object` | `deserializeTypedFromScalar(com.fasterxml.jackson.core.JsonParser jp, DeserializationContext ctxt)` 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.

    `com.fasterxml.jackson.annotation.JsonTypeInfo.As` | `getTypeInclusion()` Accessor for type information inclusion method that deserializer uses; indicates how type information is (expected to be) embedded in JSON input.

          protected AsWrapperTypeDeserializer(AsWrapperTypeDeserializer src,
                                   BeanProperty property)

  - ### Method Detail

    - #### 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).
      Specified by:
        `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.
      Specified by:
        `getTypeInclusion` in class `TypeDeserializerBase`

    - #### deserializeTypedFromObject

          public Object deserializeTypedFromObject(com.fasterxml.jackson.core.JsonParser jp,
                                          DeserializationContext ctxt)
                                            throws IOException

      Deserializing type id enclosed using WRAPPER_OBJECT style is straightforward
      Specified by:
        `deserializeTypedFromObject` in class `TypeDeserializer`
      Throws:
        `IOException`

    - #### 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).
      Specified by:
        `deserializeTypedFromArray` in class `TypeDeserializer`
      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).
      Specified by:
        `deserializeTypedFromScalar` in class `TypeDeserializer`

                                         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).
      Specified by:
        `deserializeTypedFromAny` in class `TypeDeserializer`
      Throws:
        `IOException`
