Interface Serializers

All Known Implementing Classes:

Serializers.Base, SimpleSerializers

public interface Serializers

Interface that defines API for simple extensions that can provide additional serializers for various types. Access is by a single callback method; instance is to either return a configured JsonSerializer for specified type, or null to indicate that it does not support handling of the type. In latter case, further calls can be made for other providers; in former case returned serializer is used for handling of instances of specified type.

Nested Class Summary

static class

Serializers.Base Basic Serializers implementation that implements all methods but provides no serializers.

Method Summary

JsonSerializer<?>	findArraySerializer(SerializationConfig config, ArrayType type, BeanDescription beanDesc, TypeSerializer elementTypeSerializer, JsonSerializer<Object> elementValueSerializer) Method called by serialization framework first time a serializer is needed for specified array type.
JsonSerializer<?>	findCollectionLikeSerializer(SerializationConfig config, CollectionLikeType type, BeanDescription beanDesc, TypeSerializer elementTypeSerializer, JsonSerializer<Object> elementValueSerializer) Method called by serialization framework first time a serializer is needed for specified "Collection-like" type (type that acts like Collection, but does not implement it).
JsonSerializer<?>	findCollectionSerializer(SerializationConfig config, CollectionType type, BeanDescription beanDesc, TypeSerializer elementTypeSerializer, JsonSerializer<Object> elementValueSerializer) Method called by serialization framework first time a serializer is needed for specified Collection type.
JsonSerializer<?>	findMapLikeSerializer(SerializationConfig config, MapLikeType type, BeanDescription beanDesc, JsonSerializer<Object> keySerializer, TypeSerializer elementTypeSerializer, JsonSerializer<Object> elementValueSerializer) Method called by serialization framework first time a serializer is needed for specified "Map-like" type (type that acts like Map, but does not implement it).
JsonSerializer<?>	findMapSerializer(SerializationConfig config, MapType type, BeanDescription beanDesc, JsonSerializer<Object> keySerializer, TypeSerializer elementTypeSerializer, JsonSerializer<Object> elementValueSerializer) Method called by serialization framework first time a serializer is needed for specified Map type.
JsonSerializer<?>	findSerializer(SerializationConfig config, JavaType type, BeanDescription beanDesc) Method called by serialization framework first time a serializer is needed for specified type, which is not of a container type (for which other methods are called).

Method Detail

findSerializer

JsonSerializer<?> findSerializer(SerializationConfig config,
                                 JavaType type,
                                 BeanDescription beanDesc)

Method called by serialization framework first time a serializer is needed for specified type, which is not of a container type (for which other methods are called).

Parameters:

type - Fully resolved type of instances to serialize

config - Serialization configuration in use

beanDesc - Additional information about type

Returns:

Configured serializer to use for the type; or null if implementation does not recognize or support type

findArraySerializer

JsonSerializer<?> findArraySerializer(SerializationConfig config,
                                      ArrayType type,
                                      BeanDescription beanDesc,
                                      TypeSerializer elementTypeSerializer,
                                      JsonSerializer<Object> elementValueSerializer)

Method called by serialization framework first time a serializer is needed for specified array type. Implementation should return a serializer instance if it supports specified type; or null if it does not.

findCollectionSerializer

                                           BeanDescription beanDesc,
                                           TypeSerializer elementTypeSerializer,
                                           JsonSerializer<Object> elementValueSerializer)

Method called by serialization framework first time a serializer is needed for specified Collection type. Implementation should return a serializer instance if it supports specified type; or null if it does not.

findCollectionLikeSerializer

JsonSerializer<?> findCollectionLikeSerializer(SerializationConfig config,
                                               CollectionLikeType type,
                                               BeanDescription beanDesc,
                                               TypeSerializer elementTypeSerializer,
                                               JsonSerializer<Object> elementValueSerializer)

Method called by serialization framework first time a serializer is needed for specified "Collection-like" type (type that acts like Collection, but does not implement it). Implementation should return a serializer instance if it supports specified type; or null if it does not.

findMapSerializer

JsonSerializer<?> findMapSerializer(SerializationConfig config,
                                    MapType type,
                                    BeanDescription beanDesc,
                                    JsonSerializer<Object> keySerializer,
                                    TypeSerializer elementTypeSerializer,
                                    JsonSerializer<Object> elementValueSerializer)
