Method Detail

initInstanceBuilder

protected InstanceBuilder<T> initInstanceBuilder()

Initialize the InstanceBuilder. Returns null if the class isn't instantiable.

initDeserializers

protected SimpleStringMap<BeanPropertyDeserializer<T,?>> initDeserializers()

Initialize the SimpleStringMap containing the property deserializers. Returns an empty map if there are no properties to deserialize.

initBackReferenceDeserializers

protected SimpleStringMap<BackReferenceProperty<T,?>> initBackReferenceDeserializers()

Initialize the SimpleStringMap containing the back reference deserializers. Returns an empty map if there are no back reference on the bean.

initIgnoredProperties

protected Set<String> initIgnoredProperties()

Initialize the Set containing the ignored property names. Returns an empty set if there are no ignored properties.

initRequiredProperties

protected Set<String> initRequiredProperties()

Initialize the Set containing the required property names. Returns an empty set if there are no required properties.

initIdentityInfo

protected IdentityDeserializationInfo<T> initIdentityInfo()

Initialize the IdentityDeserializationInfo. Returns null if there is no JsonIdentityInfo annotation on bean.

initTypeInfo

protected TypeDeserializationInfo<T> initTypeInfo()

Initialize the TypeDeserializationInfo. Returns null if there is no JsonTypeInfo annotation on bean.

initMapSubtypeClassToDeserializer

protected Map<Class,SubtypeDeserializer> initMapSubtypeClassToDeserializer()

Initialize the Map containing the SubtypeDeserializer. Returns an empty map if the bean has no subtypes.

initAnySetterDeserializer

protected AnySetterDeserializer<T,?> initAnySetterDeserializer()

Initialize the AnySetterDeserializer. Returns null if there is no method annoted with JsonAnySetter on bean.

isDefaultIgnoreUnknown

protected boolean isDefaultIgnoreUnknown()

Whether encountering of unknown properties should result in a failure (by throwing a JsonDeserializationException) or not.

getDeserializedType

public abstract Class getDeserializedType()

doDeserialize

public T doDeserialize(JsonReader reader,
              JsonDeserializationContext ctx,
              JsonDeserializerParameters params)

Description copied from class: JsonDeserializer

Deserializes a non-null JSON input into an object.

Specified by:

doDeserialize in class JsonDeserializer<T>

Parameters:

reader - JsonReader used to read the JSON input

ctx - Context for the full deserialization process

params - Parameters for this deserialization

Returns:

the deserialized object

canDeserialize

protected boolean canDeserialize()

deserializeWrapped

public T deserializeWrapped(JsonReader reader,
                   JsonDeserializationContext ctx,
                   JsonDeserializerParameters params,
                   IdentityDeserializationInfo identityInfo,
                   TypeDeserializationInfo typeInfo,
                   String typeInformation)

deserializeInline

public final T deserializeInline(JsonReader reader,
                  JsonDeserializationContext ctx,
                  JsonDeserializerParameters params,
                  IdentityDeserializationInfo identityInfo,
                  TypeDeserializationInfo typeInfo,
                  String type,
                  Map<String,String> bufferedProperties)

Deserializes all the properties of the bean. The JsonReader must be in a json object.

Parameters:

reader - reader

ctx - context of the deserialization process

type - in case of a subtype, it's the corresponding type value

bufferedProperties - Buffered properties in case the type info property was not in 1st position

getDeserializer

public AbstractBeanJsonDeserializer<T> getDeserializer()

setBackReference

public void setBackReference(String referenceName,
                    Object reference,
                    T value,
                    JsonDeserializationContext ctx)

Description copied from class: JsonDeserializer

Set the back reference.

Overrides:

setBackReference in class JsonDeserializer<T>

Parameters:

referenceName - name of the reference

reference - reference to set

value - value to set the reference to.

ctx - Context for the full deserialization process
