Hi all, suppose I have an array of comparable Foo structs which I want to access in a sorted order (e.g. a priority queue) using a BinaryHeap object (I know that for just sorting, the BinHeap is not the right tools), but I do not want to change the order of the objects in the original array.
I have two ideas on how to do this and just want to know whether they are the right way: a) Have an array of Foo*, initialize it from the original and instantiate the BinaryHeap with a Comparision-predicate that dereferences first. b) Have an array of indices that are indicies in the original array (like a permutation in a permutation group) and access the corresponding index of the original array for comparison. Any further ideas for this problem, or did I cover everything already? Matthias
