Detailed Description

Indirector

Allows using an indirection field for STL algorithms, e.g. sort.

The idea is to sort an index field instead of the actual data, as the data might be large or immovable.

Example:

std::vector<float> contv; std::vector<int> indv; indirector<std::vector<float>, int> ind(contv);

std::sort(indv.begin(), indv.end(), ind);
