From the docs:
If a mutable object is added to a collection that uses hash values to determine the object’s position in the collection, the value returned by thehash method of the object must not change while the object is in the collection. Therefore, either the hash method must not rely on any of the object’s internal state information or you must make sure the object’s internal state information does not change while the object is in the collection.
That's pretty hard to deal with. Returning 0 is certainly simpler :p -- Seth Willits _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
