All Implemented Interfaces:

Serializers, Serializable

public class SimpleSerializers
extends Serializers.Base
implements Serializable

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.

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 -

                              JsonSerializer<T> ser)

                                        BeanDescription beanDesc)

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).

Specified by:

Parameters:

config - Serialization configuration in use

type - Fully resolved type of instances to serialize

beanDesc - Additional information about type

Returns:

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