Detailed Description

template<class T>
class Dune::IntegralRange< T >

dynamic integer range for use in range-based for loops

Note

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

Template Parameters

T	type of integers contained in the range
