$Revision$ $Date$ NSMutableSet Foundation/NSSet.h NSCoding allocWithZone: zone setWithCapacity: numItems addObject: anObject Adds the specified object to the receiver. The object is retained by the set. addObjectsFromArray: anArray Adds all the objects in the array to the receiver. initWithCapacity: numItems Initialises the receiver to be ready to have the specified number of items added to it. Additions of items to a set initialised with an appropriate capacity will be more efficient than addition of items otherwise. intersectSet: otherSet Removes from the receiver all the objects it contains which are not also in otherSet. minusSet: otherSet Removes from the receiver all the objects that are in otherSet. removeAllObjects Removes all objects from the receiver. removeObject: anObject Removes the specified object from the receiver. setSet: otherSet Removes all objects from the receiver then adds the objects from otherSet. If the receiver is otherSet, the method has no effect. unionSet: otherSet Adds all the objects from etherSet to the receiver.
