Interface Serializers

All Known Implementing Classes:

CoreXMLSerializers, 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.

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 or reference 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

findReferenceSerializer

JsonSerializer<?> findReferenceSerializer(SerializationConfig config,
                                          ReferenceType type,
                                          BeanDescription beanDesc,
                                          TypeSerializer contentTypeSerializer,
                                          JsonSerializer<Object> contentValueSerializer)

Method called by serialization framework first time a serializer is needed for given ReferenceType
