## 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:
  Serializable

Direct Known Subclasses:
  AsExternalTypeDeserializer, AsPropertyTypeDeserializer

    public class AsArrayTypeDeserializer
    extends TypeDeserializerBase
    implements 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.

### Method Summary

Methods
`protected String` `_locateTypeId(JsonParser jp, DeserializationContext ctxt)`
`Object` `deserializeTypedFromAny(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(JsonParser jp, DeserializationContext ctxt)` Method called when actual object is serialized as JSON Array.
`Object` `deserializeTypedFromObject(JsonParser jp, DeserializationContext ctxt)` Method called when actual object is serialized as JSON Object
`Object` `deserializeTypedFromScalar(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.
`JsonTypeInfo.As` `getTypeInclusion()` Accessor for type information inclusion method that deserializer uses; indicates how type information is (expected to be) embedded in JSON input.

### Constructor Detail

#### AsArrayTypeDeserializer

    public AsArrayTypeDeserializer(JavaType bt,
                           TypeIdResolver idRes,
                           String typePropertyName,
                           boolean typeIdVisible,
                           Class<?> defaultImpl)

#### AsArrayTypeDeserializer

    public AsArrayTypeDeserializer(AsArrayTypeDeserializer 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 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 Object deserializeTypedFromArray(JsonParser jp,
                                   DeserializationContext ctxt)
                                     throws IOException,
                                            JsonProcessingException

Method called when actual object is serialized as JSON Array.

Specified by:
  `deserializeTypedFromArray` in class `TypeDeserializer`
Throws:
  `IOException`
  `JsonProcessingException`

#### deserializeTypedFromObject

    public Object deserializeTypedFromObject(JsonParser jp,
                                    DeserializationContext ctxt)
                                      throws IOException,
                                             JsonProcessingException

Method called when actual object is serialized as JSON Object

Specified by:
  `deserializeTypedFromObject` in class `TypeDeserializer`
Throws:
  `IOException`
  `JsonProcessingException`

#### deserializeTypedFromScalar

    public Object deserializeTypedFromScalar(JsonParser jp,
                                    DeserializationContext ctxt)
                                      throws IOException,
                                             JsonProcessingException

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`
  `JsonProcessingException`

#### deserializeTypedFromAny

    public Object deserializeTypedFromAny(JsonParser jp,
                                 DeserializationContext ctxt)
                                   throws IOException,
                                          JsonProcessingException

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`
  `JsonProcessingException`

#### _locateTypeId

    protected final String _locateTypeId(JsonParser jp,
                       DeserializationContext ctxt)
                                  throws IOException,
                                         JsonProcessingException

Throws:
  `IOException`
  `JsonProcessingException`
