I have a std::multiset
which stores elements of class A
. I have provided my own implementation of operator<
for this class. My question is if I insert two equivalent objects into this multiset is their order guaranteed? For example, first I insert a object a1
into the set and then I insert an equivalent object a2
into this set. Can I expect the a1
to come before a2
when I iterate through the set? If no, is there any way to achieve this using multiset?
