NSIndexSet

  • Subject: NSIndexSet
  • From: Matthew Johnson <email@hidden>

I am implementing a category on NSIndexSet that includes a method -
(BOOL)intersectsIndexes:(NSIndexSet *)indexSet. The implementation of
this will have to loop through one of the index sets and check for
intersection using containsIndex and intersectsIndexesInRange. I am
wondering whether it would generally be quicker to loop through the
smaller index set or perform the intersection tests on the smaller
index set. Opinions?

Thanks!
Matthew
