This directory contains two versions, one prototype-based and the other one class-based, of a very simple geometric shapes hierarchy.

The aim of this example is to compare the pros and cons of using either prototypes or classes for defining object hierarchies.

[112, 104]

prototype-based version

[99, 104]

class-based version

Both versions define the following hierarchy of objects:

shape
        polygon
                regular_polygon
                        square
                                q1
                                q2
