Description

template<class GridView, class AmgTraits, bool isParallel>
struct Dumux::LinearAlgebraPreparator< GridView, AmgTraits, isParallel >

Prepare the linear algebra member variables.

At compile time, correct constructor calls have to be chosen, depending on whether the setting is parallel or sequential. Since several template parameters are present, this cannot be solved by a full function template specialization. Instead, class template specialization has to be used. This adapts example 4 from http://www.gotw.ca/publications/mill17.htm.

This class template implements the function for the sequential case.

Template Parameters

isParallel

decides if the setting is parallel or sequential
