Note that NSMutableSet is a class cluster. Class NSMutableSet itself does not implement any storage. If you want to subclass NSMutableSet, you'll need to implement the storage and all of the core methods from NSSet and NSMutableSet yourself. Note that NSSet and NSMutableSet define set member equality as -isEqual:. Violating that in a subclass may break other code. -- Greg Parker gpar...@apple.com Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
