Field Summary

Fields

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

Constructor Summary

Constructors

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

Method Summary

Modifier and Type	Method	Description
static ObjectIdReader	construct(JavaType idType, PropertyName propName, ObjectIdGenerator<?> generator, ValueDeserializer<?> 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.
ValueDeserializer<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 p, 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).

Field Details

_idType

protected final JavaType _idType

propertyName

public final PropertyName propertyName

generator

public final ObjectIdGenerator<?> generator

Blueprint generator instance: actual instance will be fetched from SerializationContext using this as the key.

resolver

public final ObjectIdResolver resolver

_deserializer

protected final ValueDeserializer<Object> _deserializer

Deserializer used for deserializing id values.

idProperty

public final SettableBeanProperty idProperty

Constructor Details

ObjectIdReader

protected ObjectIdReader(JavaType t,
 PropertyName propName,
 ObjectIdGenerator<?> gen,
 ValueDeserializer<?> deser,
 SettableBeanProperty idProp,
 ObjectIdResolver resolver)

Method Details

construct

public static ObjectIdReader construct(JavaType idType,
 PropertyName propName,
 ObjectIdGenerator<?> generator,
 ValueDeserializer<?> 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 ValueDeserializer<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.

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.

readObjectReference

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

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:

JacksonException
