The usual example is that of -a geometric "point", and is introduced in :ref:`mapper_composite`. +a geometric "point", and is introduced in ref_mapper_composite. As is the case with :class:`.Mutable`, the user-defined composite class subclasses :class:`.MutableComposite` as a mixin, and detects and delivers change events to its parents via the :meth:`.MutableComposite.changed` method. In the case of a composite class, the detection is usually via the usage of the special Python method ``__setattr__()``. In the example below, we expand upon the ``Point`` -class introduced in :ref:`mapper_composite` to include +class introduced in ref_mapper_composite to include :class:`.MutableComposite` in its bases and to route attribute set events via ``__setattr__`` to the :meth:`.MutableComposite.changed` method:: |
