Pattern Pluggable Selector

Avoid gratuitous subclasses by dynamically invoking different methods for different instances.

Descritto nel libro 'Test-Driven Development: By Example', Kent Beck, Three Rivers Institute, 2002

E una variazione del PatternTemplateMethod.

How do you invoke different behavior for different instances? Store the name of a method, and dynamically invoke the method.

The Pluggable Selector solution is to dynamically invoke the method using reflection.

Only use Pluggable Selector when you are cleaning up a fairly straightforward situation in which a bunch of subclasses each have only one method.
