Does using lists of structs make sense in cocoa?

Question

This question has spawned out of this one. Working with lists of structs in cocoa is not simple. Either use NSArray and encode/decode, or use a C type array and lose the com

Answer 1

In general, the use of a struct implies the existence of a relatively simple data type that has no logic associated with it nor should have any logic associated with it. Take an NSPoint for instance - it is merely a (x,y) representation. Given this, there are also some issues that arise from it's use. In general, this is OK for this type of data as we usually observe for a change in the point rather than the y-coordinate of a point (fundamentally, (0,1) isn't the same as (1,1) shifted down by 1 unit). If this is an undesirable behavior, it may be a better idea to use a class.
