The UniqueCollection type provides the shared functionality of the OrderedSet and Set collections for which the elements are unique. The common supertype of UniqueCollection is Collection.
-(s : UniqueCollection(OclAny)) : UniqueCollection(T)
The elements of
self, which are not in s.
intersection(c : Collection(T)) : Set(T)
The intersection of
self and c (i.e., the set of all elements that are in both
self and c).
symmetricDifference(s : UniqueCollection(OclAny)) : Set(T)
The set containing all the elements that are in
self or s, but not in both.
union(s : UniqueCollection(T)) : Set(T)
The set consisting of all elements in
self and all elements in s.
sortedBy(i : T[?] | lambda : Lambda T() : OclAny[?]) : OrderedSet(T)
Results in the ordered set containing all elements of the source collection. The element for which body has the lowest value comes first, and so on. The type of the body expression must have the < operation defined. The < operation must return a Boolean value and must be transitive (i.e., if a < b and b < c, then a < c).
