Detailed Description

template<class Iterator>
class SimTK::IteratorRange< Iterator >

Helper class to use range-based for loops with a pair of iterators.

This class should only be used when you're sure the iterators are valid. Don't use this class directly; instead, use makeIteratorRange().

Here's an example of using iterators first and last to iterate over the range [first, last) (that is, last won't be reached):

std::vector<int> v {5, 10, 15, 20, 22};
auto first = std::lower_bound(v.begin(), v.end(), 10);
auto last = std::lower_bound(v.begin(), v.end(), 15); // actually points to 20.
for (auto& x : makeIteratorRange(first, last)) {
    ...
}

You can also use this class with an std::pair of iterators, such as that returned by std::multimap::equal_range(). We assume the first iterator in the pair is the first iterator in the range, and the second iterator in the pair is the last iterator in the range.

std::multimap<std::string, int> map;
...
for (auto& x : makeIteratorRange(map.equal_range("some_key"))) {
    ...
}
