-
+ setWithCapacity:
Creates and returns a mutable set with a given initial capacity.
Instance Method Summary (collapse)
-
- addObject:
Adds a given object to the set, if it is not already a member.
-
- addObjectsFromArray:
Adds to the set each object contained in a given array that is not already a member.
-
- filterUsingPredicate:
Evaluates a given predicate against the set’s content and removes from the set those objects for which the predicate returns false.
-
- initWithCapacity:
Returns an initialized mutable set with a given initial capacity.
-
- intersectSet:
Removes from the receiving set each object that isn’t a member of another given set.
-
- minusSet:
Removes each object in another given set from the receiving set, if present.
-
- removeAllObjects
Empties the set of all of its members.
-
- removeObject:
Removes a given object from the set.
-
- setSet:
Empties the receiving set, then adds each object contained in another given set.
-
- unionSet:
Adds each object in another given set to the receiving set, if not present.

Class Method Details
+ (Object) setWithCapacity(numItems)
Creates and returns a mutable set with a given initial capacity. Mutable sets allocate additional memory as needed, so numItems simply establishes the object’s initial capacity.
Instance Method Details
- (Object) addObject(object)
Adds a given object to the set, if it is not already a member.
- (Object) addObjectsFromArray(array)
Adds to the set each object contained in a given array that is not already a member.
- (Object) filterUsingPredicate(predicate)
Evaluates a given predicate against the set’s content and removes from the set those objects for which the predicate returns false. The following example illustrates the use of this method.
- (Object) initWithCapacity(numItems)
Returns an initialized mutable set with a given initial capacity. Mutable sets allocate additional memory as needed, so numItems simply establishes the object’s initial capacity.
- (Object) intersectSet(otherSet)
Removes from the receiving set each object that isn’t a member of another given set.
- (Object) minusSet(otherSet)
Removes each object in another given set from the receiving set, if present.
- (Object) removeAllObjects
Empties the set of all of its members.
- (Object) removeObject(object)
Removes a given object from the set.
- (Object) setSet(otherSet)
Empties the receiving set, then adds each object contained in another given set.
- (Object) unionSet(otherSet)
Adds each object in another given set to the receiving set, if not present.
