Hey all, I'm just looking at composite BOs, which contain an array of other BOs inside them, and looking at some ways to expose the array of objects inside it.
If we were talking about Comments on a BlogPost some things I was looking at where: BlogPost.getComment() where it returns the array by reference. I'm not so keen on this one because it allows full access to the underlying array, and doesn't stop anyone from adding the wrong sort of object to the array BlogPost.getComment() where it returns a new array in which the Comment BO's are copied into it. I think this is slightly better than the above, as the array from within the BlogPost is still encapsulated, and you can write your BlogPost.addComment(...), BlogPost.removeComment(...) etc methods from here. Having functions along the lines of: BlogPost.addComment(...) : void BlogPost.removeComment(...) : void BlogPost.clearComments() : void BlogPost.containsComment(...) : boolean BlogPost.getCommentIterator() : java.util.Iterator - which is used to give the ability to loop through the items in a Array. I prefer this approach, as you can finely decide which of these methods are appropriate for use on a BO, but obviously uses the underlying Vector of a CFArray to create the Iterator. I'm just wondering your thoughts on your preferred approach (I hate to say 'best'), and if you can see any issues with any of the above methods, particularly exposing an Iterator.
