The purpose of an object is for it to be a "black box", so if a calling page creates or references one it should have no idea what is inside that object -- what other objects it references or inherits from. This encapsulation means that if you don't like the way the object is currently constructed, you can change its internal componentns -- you can add new objects or remove what you perceive to be redundant objects without affecting the calling page one iota. This is the reason that you're also not supposed to "reach through" an object to manipulate one of its internals. Factories and service locators are sort of an exception because their sole purpose is to create, maintain and return objects which the factory ultimately doesn't utilize or care about. What you're looking at may be well formed OO or it may indeed be spaghetti if the original author did a bad job of encapsulating his objects. The real test for non-spaghetti in an OO application is that each object can be used by another object or calling page without knowing anything about its internal structure. Beyond that there's a fair amount of debate about when to create another sub-object. s. isaac dealey 434.293.6201 new epoch : isn't it time for a change? add features without fixtures with the onTap open source framework http://www.fusiontap.com http://coldfusion.sys-con.com/author/4806Dealey.htm ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:235465 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
