blaze::IsColumn< T > Struct Template Reference

Compile time check for columns.This type trait tests whether or not the given template parameter is a column (i.e. dense or sparse column). In case the type is a column, the value member constant is set to true, the nested type definition Type is TrueType, and the class derives from TrueType.

Detailed Description

template<typename T>
struct blaze::IsColumn< T >

Compile time check for columns.

This type trait tests whether or not the given template parameter is a column (i.e. dense or sparse column). In case the type is a column, 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.
