Your comparator only compares by length, that means that equally-sized but different strings are treated as being equivalent bystd::set. (std::settreats them equally if neithera < bnorb < aare true, with<being your custom comparator function.) That means your comparator should also consider ...
private TreeSet<PositionReport> positionReports = new TreeSet<>(Comparator.comparingLong(PositionReport::getTimestamp)); PositionReportis a rather simple class defined like this: public static final class PositionReport implements Cloneable { private final long timestamp; private final Position position...
I've got a std::set with a custom comparator. When I add things, it puts them in the right place. When I change these objects (and I can tell they are effectively changed), the set doesn't 'auto-sort' with these changes. How can I do this? I store pointe
and keys. Now, if you had some kind of custom comparator to make your stored values compared with dereferencing, then you might get closer to achieving what you want. Look at the second template argument for std::set. V Dec 17 '05 #2 Kai-Uwe Bux da***@my-deja.com wrote: I ne...

Are you tired of creating comparators or hashes for your custom class? I have a solution for you. Sometimes we need to use STL data structures such as map, unordered_map or set using a data type that doesn't have a hash or a comparator. Instead of coding things properly I will show...
