-            Add a value factory. Attempting to add a factory with an id for which a factory is already registered throws
-            AlreadyRegisteredException.
-            When unmarshaling an Ice value, the Ice run time reads the most-derived type id off the wire and attempts to
-            create an instance of the type using a factory. If no instance is created, either because no factory was found,
-            or because all factories returned nil, the behavior of the Ice run time depends on the format with which the
-            value was marshaled:
-            If the value uses the "sliced" format, Ice ascends the class hierarchy until it finds a type that is recognized
-            by a factory, or it reaches the least-derived type. If no factory is found that can create an instance, the run
-            time throws NoValueFactoryException.
-            If the value uses the "compact" format, Ice immediately raises NoValueFactoryException.
-            The following order is used to locate a factory for a type:
-            The Ice run-time looks for a factory registered specifically for the type.
-            If no instance has been created, the Ice run-time looks for the default factory, which is registered with
-            an empty type id.
-            If no instance has been created by any of the preceding steps, the Ice run-time looks for a factory that
-            may have been statically generated by the language mapping for non-abstract classes.
-        Arguments:
-        factory -- The factory to add.
-        id -- The type id for which the factory can create instances, or an empty string for the default factory.
