Overview

This class is abstract.

Specialized upcaster mixin for an upcaster that upcasts a serialized object into a single, newer serialized object.

This mixin is not suitable if an upcaster needs to upcast a serialized object into multiple newer serialized objects, or when the output representation type is not the same as the expected representation type.
