to the individual sets. Iterates by pulling the iterators of the
individual sets. Just creating the composite set happens in O(1) by assigning the passed array of
sets. The contains-check performs in O(n) is n is the number of sets held by this composite set and
assuming that the individual sets can perform their contains-check in O(1). The composite set is
unmodifiable. All modifying operations throw an exception.Constructor and Description |
