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

    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. 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,
