Method Summary

Methods

Modifier and Type	Method and Description
protected BeanSerializerBase	asArraySerializer() JSON Array output can not be done if unwrapping operation is requested; so implementation will simply return 'this'.
boolean	isUnwrappingSerializer() Accessor for checking whether this serializer is an "unwrapping" serializer; this is necessary to know since it may also require caller to suppress writing of the leading property name.
void	serialize(Object bean, JsonGenerator jgen, SerializerProvider provider) Main serialization method that will delegate actual output to configured BeanPropertyWriter instances.
String	toString()
JsonSerializer<Object>	unwrappingSerializer(NameTransformer transformer) Method that will return serializer instance that produces "unwrapped" serialization, if applicable for type being serialized (which is the case for some serializers that produce JSON Objects as output).
protected UnwrappingBeanSerializer	withIgnorals(String[] toIgnore) Fluent factory used for creating a new instance with additional set of properties to ignore (from properties this instance otherwise has)
UnwrappingBeanSerializer	withObjectIdWriter(ObjectIdWriter objectIdWriter) Fluent factory used for creating a new instance with different ObjectIdWriter.

Method Detail

unwrappingSerializer

public JsonSerializer<Object> unwrappingSerializer(NameTransformer transformer)

Description copied from class: JsonSerializer

Method that will return serializer instance that produces "unwrapped" serialization, if applicable for type being serialized (which is the case for some serializers that produce JSON Objects as output). If no unwrapped serializer can be constructed, will simply return serializer as-is.

Default implementation just returns serializer as-is, indicating that no unwrapped variant exists

Overrides:

unwrappingSerializer in class JsonSerializer<Object>

Parameters:

transformer - Name transformation to use to convert between names of unwrapper properties

isUnwrappingSerializer

public boolean isUnwrappingSerializer()

Description copied from class: JsonSerializer

Accessor for checking whether this serializer is an "unwrapping" serializer; this is necessary to know since it may also require caller to suppress writing of the leading property name.

Overrides:

isUnwrappingSerializer in class JsonSerializer<Object>

withObjectIdWriter

public UnwrappingBeanSerializer withObjectIdWriter(ObjectIdWriter objectIdWriter)

Description copied from class: BeanSerializerBase

Fluent factory used for creating a new instance with different ObjectIdWriter.

Specified by:

withObjectIdWriter in class BeanSerializerBase

withIgnorals

protected UnwrappingBeanSerializer withIgnorals(String[] toIgnore)

Description copied from class: BeanSerializerBase

Fluent factory used for creating a new instance with additional set of properties to ignore (from properties this instance otherwise has)

Specified by:

withIgnorals in class BeanSerializerBase

asArraySerializer

protected BeanSerializerBase asArraySerializer()

JSON Array output can not be done if unwrapping operation is requested; so implementation will simply return 'this'.

Specified by:

asArraySerializer in class BeanSerializerBase

serialize

public final void serialize(Object bean,
             JsonGenerator jgen,
             SerializerProvider provider)
                     throws IOException,
                            JsonGenerationException

Main serialization method that will delegate actual output to configured BeanPropertyWriter instances.

Specified by:

serialize in class BeanSerializerBase

Parameters:

bean - Value to serialize; can not be null.

jgen - Generator used to output resulting Json content

provider - Provider that can be used to get serializers for serializing Objects value contains, if any.

Throws:

IOException

JsonGenerationException

toString

public String toString()

Overrides:

toString in class Object
