18.1 Constraints

  • The problem is decomposed using some form of abstraction (procedures, functions, objects, etc.).
  • Aspects of the problem are added to the main program without any edits to the source code of the abstractions or the sites that use them.
  • An external binding mechanism binds the abstractions with the aspects.
