Adaptive Object-Oriented Software: The Demeter Method with Propagation Patterns

Update: 02/07/2017: the book’s URL is no longer accessible. Replaced it a mirror URL. Book excerpts: This book presents a complete methodology for adaptive programming in any object-oriented language. Lieberherr’s method provides a new approach to object-oriented program design that goes beyond object encapsulation and hard-coded navigation paths to achieve more flexible interactions among objects. Designers using this adaptive method work at a higher, more schematic level of abstraction to design software programs. Graph notation is used to represent the class structure of the program, and a “propagation pattern” language describes how to distribute meaningful methods (including navigation) across the program’s structure. Using this method, software designers can create programs that are easily modified and adaptable as needs evolve.
