Detailed Description

template<class DVL, class Compare, class DVL_Base = typename DVL::DVL_BASE>
struct DataModel_detail::Compwrapper< DVL, Compare, DVL_Base >

Comparison helper for DataVector/List classes.

When doing operations such as sort on a DataVector/List, we'd like to be able to give to sort the iterators of the underlying BaseContainer container, for the sake of efficiency. But we also have to make sure that the comparisons see the proper pointer types for derived DataVector/List classes. This can be done with the following functional wrapper. This wraps a comparison object, putting the arguments through DVLCast before calling the comparison.

There is also a specialization for the case where no casting is required.
