Collection Switch Design Pattern Link http://www.ewp.rpi.edu/hartford/~rhb/cs_seminar_2005/SessionD3/gresh.pdf Abstract A design pattern for the elimination of lengthy conditional statements named the Collection Switch is presented. The design pattern presented will provide software developers a powerful tool to argue against the implementation of systems that do not scale well as a consequence of the need to maintain conditional mappings such as lengthy if-then-else statements, hash maps, XML representations of conditional logic, etc. The design pattern presented uses a collection of objects that implement a common interface and dynamic class loading to replace lengthy conditional logic. Aformal methodology is presented and applied to demonstrate that using the Collection Switch pat
