# Ice::CloneNotImplementedException

## Overview

### [ "cpp:ice_print" ] local exception CloneNotImplementedException

An attempt was made to clone a class that does not support cloning. This exception is raised if `ice_clone` is called on a class that is derived from an abstract Slice class (that is, a class containing operations), and the derived class does not provide an implementation of the `ice_clone` operation (C++ only).
