Chapter 9 -- Prototypical Object Factory

Chapter 9

When the term "clone" is used, we often think of a product that is an exact duplicate of an original. Cloned products in many cases are created by using information gathered through reverse engineering the original. However, in spite of the fact that we expect clones to be exact duplicates, we still often perceive that the quality is deprecated in a clone. Furthermore if you clone the clone, you might expect the quality to further diminish.

In software development, however, a clone and the original are identical in every respect. When you use the Prototypical Object Factory design pattern, the responsibility for producing a clone of an object resides with the object itself. No reverse engineering is required. This feature plays a key role in creating an application that permits plug-and-play of new functionality at run time.
