Let's say.. there's a Room. Room has Window, and Door. Room has a state (empty, not empty). And this Room is smart that it only lets you close the Window when it is not empty.
So.. we have: Room.isEmpty() Window.open() Window.close() Now... since Window.close() needs to check if room is empty first, what should be a better solution? // Solution1: Room.init() Window.init(room) // window has reference to Room Window.close() // checks if Room is empty first by calling room.isEmpty() > Room.getWindow().close() // Solution2: Room.init(Window window) Window.init() // window has no reference to Room Window.close() // will close itself w/o checking > Room.closeWindow() // Room object checks if it isEmpty(), if yes, then it > calls window.close() What do you guys think? Which one is the better solution? Why? base on which OO principle? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "CFCDev" group.
