Generically speaking, "getters and setters" are any routine that you can (must ...) call to affect a value that you can't access directly – because it is inside of a closure or an object. In the general sense, they often have "side effects." For instance, calling a "color setter" actually causes the color of something to change, and also completely conceals the mechanics of how that actually happens.	[reply]
