Interface Serializers

All Known Implementing Classes:

Serializers.Base, Serializers.None, 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.

1.7

Method Detail

findSerializer

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

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).

Note: in version 1.7, this method was called to find serializers for all type, including container types.

Parameters:

type - Fully resolved type of instances to serialize

config - Serialization configuration in use

beanDesc - Additional information about type; will always be of type BasicBeanDescription (that is, safe to cast to this more specific type)

property - Property that contains values to serialize

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,
                                    BeanProperty property,
                                    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.

1.8
