Detailed Description

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

Compile time check for sparse matrix types.

This type trait tests whether or not the given template parameter is a sparse matrix type (i.e. whether T is derived from the SparseMatrix base class). In case the type is a sparse matrix type, 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.

using namespace blaze;
IsSparseMatrix< CompressedMatrix<double> >::value // Evaluates to 1
IsSparseMatrix< const CompressedMatrix<float> >::Type // Results in TrueType
IsSparseMatrix< volatile CompressedMatrix<int> > // Is derived from TrueType
IsSparseMatrix< DynamicVector<double> >::value // Evaluates to 0
IsSparseMatrix< const DynamicMatrix<double> >::Type // Results in FalseType
IsSparseMatrix< CompressedVector<double> > // Is derived from FalseType
