blaze::HasAbs< T, typename > Struct Template Reference

Availability of the abs() operation for the given data types.This type trait provides the information whether the abs() operation exists for the given data type T (taking the cv-qualifiers into account). In case the operation is available, 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. More...

Detailed Description

template<typename T, typename = void>
struct blaze::HasAbs< T, typename >

Availability of the abs() operation for the given data types.

This type trait provides the information whether the abs() operation exists for the given data type T (taking the cv-qualifiers into account). In case the operation is available, 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.

struct NoAbs {}; // Definition of a type without the abs() operation
blaze::HasAbs< int >::value // Evaluates to 1
blaze::HasAbs< DynamicVector<float> >::Type // Results in TrueType
blaze::HasAbs< DynamicMatrix<double> > // Is derived from TrueType
blaze::HasAbs< NoAbs >::Type // Results in FalseType
blaze::HasAbs< NoAbs > // Is derived from FalseType
