template<typename T>
struct blaze::IsRows< T >
Compile time check for row selections.
This type trait tests whether or not the given template parameter is a row selection (i.e. a view on rows of a dense or sparse matrix). In case the type is a row selection, the value member constant is set to true, the nested type definition Type is TrueType, and the class derives from TrueType. Otherwise value is set to false, Type is FalseType, and the class derives from FalseType.
