Class UnwrappingBeanSerializer

    • Method Detail

      • unwrappingSerializer

        public JsonSerializer<Object> unwrappingSerializer​(NameTransformer transformer)
        Description copied from class: JsonSerializer
        Method that will return serializer instance that produces "unwrapped" serialization, if applicable for type being serialized (which is the case for some serializers that produce JSON Objects as output). If no unwrapped serializer can be constructed, will simply return serializer as-is.

        Default implementation just returns serializer as-is, indicating that no unwrapped variant exists

      • isUnwrappingSerializer

        public boolean isUnwrappingSerializer()
        Description copied from class: JsonSerializer
        Accessor for checking whether this serializer is an "unwrapping" serializer; this is necessary to know since it may also require caller to suppress writing of the leading property name.

      • serializeWithType

        public void serializeWithType​(Object bean,
                                      JsonGenerator gen,
                                      SerializerProvider provider,
                                      TypeSerializer typeSer)
                               throws IOException
        Description copied from class: JsonSerializer
        Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

        Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

        For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like:

          // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
          typeSer.writeTypePrefixForScalar(value, gen);
          serialize(value, gen, provider);
          typeSer.writeTypeSuffixForScalar(value, gen);
        and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY/END-ARRAY and START-OBJECT/END-OBJECT pairs need to be properly handled with respect to serializing of contents.

        bean - Value to serialize; can not be null.
        gen - Generator used to output resulting Json content
        provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
        typeSer - Type serializer to use for including type information
