public class BeanSerializer
extends BeanSerializerBase

Serializer class that can serialize Java objects that map to JSON Object output. Internally handling is mostly dealt with by a sequence of BeanPropertyWriters that will handle access value to serialize and call appropriate serializers to write out JSON.

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

Constructors

Modifier	Constructor and Description
protected	BeanSerializer(BeanSerializerBase src) Alternate copy constructor that can be used to construct standard BeanSerializer passing an instance of "compatible enough" source serializer.
protected	BeanSerializer(BeanSerializerBase src, ObjectIdWriter objectIdWriter)
protected	BeanSerializer(BeanSerializerBase src, ObjectIdWriter objectIdWriter, Object filterId)
protected	BeanSerializer(BeanSerializerBase src, Set<String> toIgnore)
	BeanSerializer(JavaType type, BeanSerializerBuilder builder, BeanPropertyWriter[] properties, BeanPropertyWriter[] filteredProperties)

Method Summary

Modifier and Type	Method and Description
protected BeanSerializerBase	asArraySerializer() Implementation has to check whether as-array serialization is possible reliably; if (and only if) so, will construct a BeanAsArraySerializer, otherwise will return this serializer as is.
static BeanSerializer	createDummy(JavaType forType) Method for constructing dummy bean serializer; one that never outputs any properties
void	serialize(Object bean, JsonGenerator gen, SerializerProvider provider) Main serialization method that will delegate actual output to configured BeanPropertyWriter instances.
String	toString()
JsonSerializer<Object>	unwrappingSerializer(NameTransformer unwrapper) 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).
BeanSerializerBase	withFilterId(Object filterId) Mutant factory used for creating a new instance with different filter id (used with JsonFilter annotation)
protected BeanSerializerBase	withIgnorals(Set<String> toIgnore) Mutant factory used for creating a new instance with additional set of properties to ignore (from properties this instance otherwise has)
BeanSerializerBase	withObjectIdWriter(ObjectIdWriter objectIdWriter) Mutant factory used for creating a new instance with different ObjectIdWriter.

Constructor Detail

BeanSerializer

public BeanSerializer(JavaType type,
                      BeanSerializerBuilder builder,
                      BeanPropertyWriter[] properties,
                      BeanPropertyWriter[] filteredProperties)

Parameters:

builder - Builder object that contains collected information that may be needed for serializer

properties - Property writers used for actual serialization

BeanSerializer

protected BeanSerializer(BeanSerializerBase src)

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

BeanSerializer

protected BeanSerializer(BeanSerializerBase src,
                         ObjectIdWriter objectIdWriter)

BeanSerializer

protected BeanSerializer(BeanSerializerBase src,
                         ObjectIdWriter objectIdWriter,
                         Object filterId)

BeanSerializer

protected BeanSerializer(BeanSerializerBase src,
                         Set<String> toIgnore)

Method Detail

createDummy

public static BeanSerializer createDummy(JavaType forType)

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

unwrappingSerializer

public JsonSerializer<Object> unwrappingSerializer(NameTransformer unwrapper)

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:

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

withObjectIdWriter

public BeanSerializerBase withObjectIdWriter(ObjectIdWriter objectIdWriter)

Description copied from class: BeanSerializerBase

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

Specified by:

withObjectIdWriter in class BeanSerializerBase

withFilterId

public BeanSerializerBase withFilterId(Object filterId)

Description copied from class: BeanSerializerBase

Mutant factory used for creating a new instance with different filter id (used with JsonFilter annotation)

Specified by:

withFilterId in class BeanSerializerBase

withIgnorals

protected BeanSerializerBase withIgnorals(Set<String> toIgnore)

Description copied from class: BeanSerializerBase

Mutant 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()

Implementation has to check whether as-array serialization is possible reliably; if (and only if) so, will construct a BeanAsArraySerializer, otherwise will return this serializer as is.

Specified by:

asArraySerializer in class BeanSerializerBase

serialize

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

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.

gen - 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

toString

public String toString()

Overrides:

toString in class Object
