Detailed Description

template<typename T>
class hermes::Index3Range< T >

Represents a closed-open range of indices [lower, upper),.

Can be used in a for each loop that iterates over all indices in the range:

hermes::size3 size(10);
for(auto ij : hermes::Index3Range<int>(size)) {
*ij; // index coordinates
}
hermes::Index3Range
