Class AsArrayTypeDeserializer

java.lang.Object

tools.jackson.databind.jsontype.TypeDeserializer

tools.jackson.databind.jsontype.impl.TypeDeserializerBase

tools.jackson.databind.jsontype.impl.AsArrayTypeDeserializer

Direct Known Subclasses:

AsExternalTypeDeserializer, AsPropertyTypeDeserializer

public class AsArrayTypeDeserializer
extends TypeDeserializerBase

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

Modifier and Type	Method	Description
protected Object	_deserialize(JsonParser p, DeserializationContext ctxt)	Method that handles type information wrapper, locates actual subtype deserializer to use, and calls it to do actual deserialization.
protected String	_locateTypeId(JsonParser p, DeserializationContext ctxt)
protected boolean	_usesExternalId()
Object	deserializeTypedFromAny(JsonParser p, 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 p, DeserializationContext ctxt)	Method called when actual object is serialized as JSON Array.
Object	deserializeTypedFromObject(JsonParser p, DeserializationContext ctxt)	Method called when actual object is serialized as JSON Object
Object	deserializeTypedFromScalar(JsonParser p, 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 Details

AsArrayTypeDeserializer

public AsArrayTypeDeserializer(JavaType bt,
 TypeIdResolver idRes,
 String typePropertyName,
 boolean typeIdVisible,
 JavaType defaultImpl)

AsArrayTypeDeserializer

public AsArrayTypeDeserializer(AsArrayTypeDeserializer src,
 BeanProperty property)

Method Details

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 p,
 DeserializationContext ctxt)
                                 throws JacksonException

Method called when actual object is serialized as JSON Array.

Specified by:

deserializeTypedFromArray in class TypeDeserializer

Throws:

JacksonException

deserializeTypedFromObject

public Object deserializeTypedFromObject(JsonParser p,
 DeserializationContext ctxt)
                                  throws JacksonException

Method called when actual object is serialized as JSON Object

Specified by:

deserializeTypedFromObject in class TypeDeserializer

Throws:

JacksonException

deserializeTypedFromScalar

public Object deserializeTypedFromScalar(JsonParser p,
 DeserializationContext ctxt)
                                  throws JacksonException

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 ValueDeserializer to use, and call it with JSON data to deserializer (which does not contain type information).

Specified by:

deserializeTypedFromScalar in class TypeDeserializer

Throws:

JacksonException

deserializeTypedFromAny

public Object deserializeTypedFromAny(JsonParser p,
 DeserializationContext ctxt)
                               throws JacksonException

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:

JacksonException

_deserialize

protected Object _deserialize(JsonParser p,
 DeserializationContext ctxt)
                       throws JacksonException

Method that handles type information wrapper, locates actual subtype deserializer to use, and calls it to do actual deserialization.

Throws:

JacksonException

_locateTypeId

protected String _locateTypeId(JsonParser p,
 DeserializationContext ctxt)
                        throws JacksonException

Throws:

JacksonException

_usesExternalId

protected boolean _usesExternalId()
