Instance Method Details
- (Array) allObjects
Returns an array of objects the receiver has yet to enumerate. Put another way, the array returned by this method does not contain objects that have already been enumerated with previous nextObject messages.Invoking this method exhausts the enumerator’s collection so that subsequent invocations of nextObject return nil.
- (Object) nextObject
Returns the next object from the collection being enumerated. The following code illustrates how this method works using an array:
