NSMapTable Value Callbacks

These are predefined sets of callbacks for NSMapTable values.


In macOS 10.5 and later, see also the NSMapTable class.

Note that you can make your own callback by picking fields among the above callbacks.



let NSIntegerMapValueCallBacks: NSMapTableValueCallBacks

For values that are pointer-sized quantities, (for example, int, long, or unichar).

let NSNonRetainedObjectMapValueCallBacks: NSMapTableValueCallBacks

For sets of objects, but without retaining/releasing.
