Frage

When I have a result of type Set(Integer), numbers are not ordered. We have an operation usable on collections called sortedBy ( expr : OclExpression ) : Sequence(T), but when there's only integers in this set, what's the expression to use?

War es hilfreich?

Lösung

You can just use the asOrderedSet operation (if your collection is in the variable X, then that would be X->asOrderedSet())

From the OCL Standard asOrderedSet() : OrderedSet(T) An OrderedSet that contains all the elements from self, with duplicates removed, in an order dependent on the particular concrete collection type.
