      Description copied from class: `JsonSerializer`
      Method that can be called to ask implementation to serialize values of type this serializer handles.
      Specified by:
        `serialize` in class `SerializerBase<Enum<?>>`
      Parameters:
        `en` - Value to serialize; can not be null.
        `jgen` - Generator used to output resulting Json content
        `provider` - Provider that can be used to get serializers for serializing Objects value contains, if any.
      Throws:
        `IOException`
        `JsonGenerationException`

    - #### getSchema

      Specified by:
        `getSchema` in interface `SchemaAware`
      Overrides:
        `getSchema` in class `ScalarSerializerBase<Enum<?>>`
      Parameters:
        `provider` - The serializer provider.
        `typeHint` - A hint about the type.
      Returns:
        Json-schema for this serializer.
