Detailed Description

template<typename ValueT, typename EnableVectorT>
class util_intops::ValueFilterView< ValueT, EnableVectorT >

This view provides access to elements of a container of integral types, which are used as indices to a filter (in) vector. The view filters and returns only those elements that, when used a subscript to the filter vector, are evaluated to a true value. Looping over this view is equivalent to:

for (decltype(auto) item : container) { if (is_active[item]) { your_code(iter); } }
