All Implemented Interfaces:

Serializers

public class SimpleSerializers
extends Serializers.Base

Simple implementation Serializers which allows registration of serializers based on raw (type erased class). It can work well for basic bean and scalar type serializers, but is not a good fit for handling generic types (like Maps and Collections).

Type registrations are assumed to be general; meaning that registration of serializer for a super type will also be used for handling subtypes, unless an exact match is found first. As an example, handler for CharSequence would also be used serializing StringBuilder instances, unless a direct mapping was found.

Since:

1.7

Method Detail

addSerializer

public void addSerializer(JsonSerializer<?> ser)

Method for adding given serializer for type that JsonSerializer.handledType() specifies (which MUST return a non-null class; and can NOT be Object, as a sanity check). For serializers that do not declare handled type, use the variant that takes two arguments.

Parameters:

ser -

addSerializer

public <T> void addSerializer(Class<? extends T> type,
                              JsonSerializer<T> ser)

findSerializer

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

Description copied from interface: Serializers

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.

Specified by:

findSerializer in interface Serializers

Overrides:

findSerializer in class Serializers.Base

Parameters:

config - Serialization configuration in use

type - Fully resolved type of instances to serialize

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

public JsonSerializer<?> findArraySerializer(SerializationConfig config,
                                             ArrayType type,

                                             BeanProperty property,
                                             TypeSerializer elementTypeSerializer,
                                             JsonSerializer<Object> elementValueSerializer)

Description copied from interface: Serializers

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.
