tools.jackson.databind.jsontype.impl.NoOpTypeDeserializer

public class NoOpTypeDeserializer
extends TypeDeserializer

Special TypeDeserializer implementation used to explicitly block type deserialization. This is used when a property or class is annotated with @JsonTypeInfo(use = Id.NONE), indicating that type information should not be expected or processed even if the value type has a class-level type info annotation.

Unlike returning null (which means "no special type handling, use defaults"), this actively prevents type information from being read.

Method Summary

Modifier and Type	Method	Description
protected Object	_deserialize(JsonParser p, DeserializationContext ctxt)
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 to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Array (regardless of Java type).
Object	deserializeTypedFromObject(JsonParser p, DeserializationContext ctxt)	Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Object (regardless of Java type).
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.
static NoOpTypeDeserializer	forBaseType(DeserializationContext ctxt, JavaType baseType)
TypeDeserializer	forProperty(BeanProperty prop)	Method called to create contextual version, to be used for values of given property.
Class<?>	getDefaultImpl()	Accessor for "default implementation" type; optionally defined class to use in cases where type id is not accessible for some reason (either missing, or cannot be resolved)
String	getPropertyName()	Name of property that contains type information, if property-based inclusion is used.
TypeIdResolver	getTypeIdResolver()	Accessor for object that handles conversions between types and matching type ids.
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 Details

forBaseType

public static NoOpTypeDeserializer forBaseType(DeserializationContext ctxt,
 JavaType baseType)

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 TypeDeserializer

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 TypeDeserializer

getPropertyName

public String getPropertyName()

Description copied from class: TypeDeserializer

Name of property that contains type information, if property-based inclusion is used.

Specified by:

getPropertyName in class TypeDeserializer

getTypeIdResolver

public TypeIdResolver getTypeIdResolver()

Description copied from class: TypeDeserializer

Accessor for object that handles conversions between types and matching type ids.

Specified by:

getTypeIdResolver in class TypeDeserializer

getDefaultImpl

public Class<?> getDefaultImpl()

Description copied from class: TypeDeserializer

Accessor for "default implementation" type; optionally defined class to use in cases where type id is not accessible for some reason (either missing, or cannot be resolved)

Specified by:

getDefaultImpl in class TypeDeserializer

deserializeTypedFromObject

public Object deserializeTypedFromObject(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 JSON 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:

deserializeTypedFromObject in class TypeDeserializer

Throws:

JacksonException

deserializeTypedFromArray

public Object deserializeTypedFromArray(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 JSON Array (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:

deserializeTypedFromArray 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

Throws:

JacksonException
