Detailed Description

template<class T, T to, T from = 0>
class Dune::StaticIntegralRange< T, to, from >

static integer range for use in range-based for loops

This is a compile-time static variant of the IntegralRange. Apart from returning all range information statically, it casts into the corresponding std::integer_sequence.

Note

This range can also be used in Hybrid::forEach, resulting in a static for loop over the contained integers like a std::integer_sequence.

Template Parameters

T	type of integers contained in the range
to	first element not contained in the range
from	first element contained in the range, defaults to 0
