Field Summary

Fields

Modifier and Type	Field and Description
protected JsonDeserializer<Object>	_deserializer Deserializer used for deserializing id values.
protected JavaType	_idType
ObjectIdGenerator<?>	generator Blueprint generator instance: actual instance will be fetched from SerializerProvider using this as the key.
SettableBeanProperty	idProperty
PropertyName	propertyName
ObjectIdResolver	resolver

Constructor Summary

Constructors

Modifier	Constructor and Description
protected	ObjectIdReader(JavaType t, PropertyName propName, ObjectIdGenerator<?> gen, JsonDeserializer<?> deser, SettableBeanProperty idProp, ObjectIdResolver resolver)

Method Summary

Modifier and Type	Method and Description
static ObjectIdReader	construct(JavaType idType, PropertyName propName, ObjectIdGenerator<?> generator, JsonDeserializer<?> deser, SettableBeanProperty idProp, ObjectIdResolver resolver) Factory method called by BeanSerializerBase with the initial information based on standard settings for the type for which serializer is being built.
JsonDeserializer<Object>	getDeserializer()
JavaType	getIdType()
boolean	isValidReferencePropertyName(String name, JsonParser parser) Convenience method, equivalent to calling: readerInstance.generator.isValidReferencePropertyName(name, parser); and used to determine whether Object Ids handled by the underlying generator may be in form of (JSON) Objects.
boolean	maySerializeAsObject() Convenience method, equivalent to calling: readerInstance.generator.maySerializeAsObject(); and used to determine whether Object Ids handled by the underlying generator may be in form of (JSON) Objects.
Object	readObjectReference(JsonParser jp, DeserializationContext ctxt) Method called to read value that is expected to be an Object Reference (that is, value of an Object Id used to refer to another object).

Method Detail

construct

public static ObjectIdReader construct(JavaType idType,
                                       PropertyName propName,
                                       ObjectIdGenerator<?> generator,
                                       JsonDeserializer<?> deser,
                                       SettableBeanProperty idProp,
                                       ObjectIdResolver resolver)

Factory method called by BeanSerializerBase with the initial information based on standard settings for the type for which serializer is being built.

getDeserializer

public JsonDeserializer<Object> getDeserializer()

getIdType

public JavaType getIdType()

maySerializeAsObject

public boolean maySerializeAsObject()

Convenience method, equivalent to calling: readerInstance.generator.maySerializeAsObject(); and used to determine whether Object Ids handled by the underlying generator may be in form of (JSON) Objects. Used for optimizing handling in cases where method returns false.

Since:

2.5

isValidReferencePropertyName

public boolean isValidReferencePropertyName(String name,
                                            JsonParser parser)

Convenience method, equivalent to calling: readerInstance.generator.isValidReferencePropertyName(name, parser); and used to determine whether Object Ids handled by the underlying generator may be in form of (JSON) Objects. Used for optimizing handling in cases where method returns false.

Since:

2.5

readObjectReference

public Object readObjectReference(JsonParser jp,
                                  DeserializationContext ctxt)
                           throws IOException

Method called to read value that is expected to be an Object Reference (that is, value of an Object Id used to refer to another object).

Throws:

IOException

Since:
