extents constructors
constexpr extents () noexcept=default
 The default constructor requires that all exts are not Std::dynamic_extent.

Detailed Description

template<class IndexType, std::size_t... exts>
class Dune::Std::extents< IndexType, exts >

Multidimensional index space with dynamic and static extents.

This class template represents a multidimensional index space of rank equal to sizeof...(exts). Each extent might be specified as a template parameter or as a dynamic parameter in the constructor.

Template Parameters
IndexTypeAn integral type other than bool
exts...Each element of exts is either Std::dynamic_extent or a representable value of type IndexType.
