## Class AsArrayTypeDeserializer

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

    `java.lang.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.
    `TypeDeserializer` | `forProperty(BeanProperty prop)` Method called to create contextual version, to be used for values of given property.
    `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.

  - ### 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`

          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`

    - #### deserializeTypedFromArray

          public java.lang.Object deserializeTypedFromArray(com.fasterxml.jackson.core.JsonParser jp,

      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).

      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).

      Throws:
        `java.io.IOException`
