Detailed Description
template<class IndexType, std::size_t... exts>
class Dune::Std::extents< IndexType, 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
-
IndexType An integral type other than bool
exts... Each element of exts is either Std::dynamic_extent
or a representable value of typeIndexType
.
