org.codehaus.jackson.map.ser.BeanSerializer

All Implemented Interfaces:

ResolvableSerializer, SchemaAware

public class BeanSerializer
extends BeanSerializerBase

Serializer class that can serialize arbitrary bean objects

Implementation note: we will post-process resulting serializer, to figure out actual serializers for final types. This must be done from BeanSerializerBase.resolve(org.codehaus.jackson.map.SerializerProvider) method, and NOT from constructor; otherwise we could end up with an infinite loop.

Since 1.7 instances are immutable; this is achieved by using a separate builder during construction process.

Constructor Summary

Constructors

Modifier	Constructor	Description
	BeanSerializer(Class<?> rawType, BeanPropertyWriter[] properties, BeanPropertyWriter[] filteredProperties, AnyGetterWriter anyGetterWriter, Object filterId)
protected	BeanSerializer(BeanSerializer src)	Copy-constructor that is useful for sub-classes that just want to copy all super-class properties without modifications.
protected	BeanSerializer(BeanSerializerBase src)	Alternate copy constructor that can be used to construct standard BeanSerializer passing an instance of "compatible enough" source serializer.
	BeanSerializer(JavaType type, BeanPropertyWriter[] properties, BeanPropertyWriter[] filteredProperties, AnyGetterWriter anyGetterWriter, Object filterId)

Method Summary

Modifier and Type	Method	Description
static BeanSerializer	createDummy(Class<?> forType)	Method for constructing dummy bean deserializer; one that never outputs any properties
final 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()	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).

Constructor Details

BeanSerializer

public BeanSerializer(JavaType type,
 BeanPropertyWriter[] properties,
 BeanPropertyWriter[] filteredProperties,
 AnyGetterWriter anyGetterWriter,
 Object filterId)

Parameters:

type - Nominal type of values handled by this serializer

properties - Property writers used for actual serialization

BeanSerializer

public BeanSerializer(Class<?> rawType,
 BeanPropertyWriter[] properties,
 BeanPropertyWriter[] filteredProperties,
 AnyGetterWriter anyGetterWriter,
 Object filterId)

BeanSerializer

protected BeanSerializer(BeanSerializer src)

Copy-constructor that is useful for sub-classes that just want to copy all super-class properties without modifications.

Since:

1.7

BeanSerializer

protected BeanSerializer(BeanSerializerBase src)

Alternate copy constructor that can be used to construct standard BeanSerializer passing an instance of "compatible enough" source serializer.

Since:

1.9

Method Details

createDummy

public static BeanSerializer createDummy(Class<?> forType)

Method for constructing dummy bean deserializer; one that never outputs any properties

unwrappingSerializer

public JsonSerializer<Object> unwrappingSerializer()

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>

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
