Method Details

objectSerializer

public static <T> Serializer<T> objectSerializer(Serializer.EncoderContext context,
 io.micronaut.core.type.Argument<? extends T> type)
                                          throws SerdeException

Select the generic object serializer for POJO-like shape handling.

Type Parameters:

T - The serialized type

Parameters:

context - The encoder context

type - The type

Returns:

The object serializer

Throws:

SerdeException

objectDeserializer

public static <T> Deserializer<T> objectDeserializer(Deserializer.DecoderContext context,
 io.micronaut.core.type.Argument<? super T> type)
                                              throws SerdeException

Select the generic object deserializer for POJO-like shape handling.

Type Parameters:

T - The deserialized type

Parameters:

context - The decoder context

type - The type

Returns:

The object deserializer

Throws:

SerdeException

updatingObjectDeserializer

public static <T> @Nullable UpdatingDeserializer<T> updatingObjectDeserializer(Deserializer.DecoderContext context,
 io.micronaut.core.type.Argument<? super T> type)
                                                                        throws SerdeException

Select the generic object deserializer only when it supports updating this type.

This is used as a merge fallback for generated deserializers that are replace-only. If the type is not object-shaped, the generic object deserializer may not be able to create a specific deserializer. In that case there is no updating fallback and callers should keep replacement semantics.

Type Parameters:

T - The deserialized type

Parameters:

context - The decoder context

type - The type

Returns:

The updating object deserializer, or null if the type cannot be updated through the object path

Throws:

SerdeException
