Use the Prototype pattern when a system should be independent of how its
products are created, composed, and represented; and
- when the classes to instantiate are specified at run-time, for
example, by dynamic loading; or
- to avoid building a class hierarchy of factories that parallels the
class hierarchy of products; or
- when instances of a class can have one of only a few different
combinations of state. It may be more convenient to install a
corresponding number of prototypes and clone them rather than
instantiating the class manually, each time with the appropriate state.
