kCFTypeSetCallBacks

Declaration

const CFSetCallBacks kCFTypeSetCallBacks;

Discussion

Predefined CFSetCallBacks structure containing a set of callbacks appropriate for use when the values in a CFSet are all CFType-derived objects. The retain callback is CFRetain, the release callback is CFRelease, the copy callback is CFCopyDescription, the equal callback is CFEqual, and the hash callback is CFHash. Therefore, if you use this constant when creating the collection, items are automatically retained when added to the collection, and released when removed from the collection.
