Detailed Description

Define base class for scalar product and norm.

These classes have to be implemented differently for different data partitioning strategies. Default implementations for the sequential case are provided.

Function Documentation

createScalarProduct()

template<class X , class Comm >

std::shared_ptr< ScalarProduct< X > > Dune::createScalarProduct	(	const Comm &	comm,
		SolverCategory::Category	category
	)

Note

Using this helper, you are responsible for the life-time management of comm

makeScalarProduct()

template<class X , class Comm >

std::shared_ptr< ScalarProduct< X > > Dune::makeScalarProduct	(	std::shared_ptr< const Comm >	comm,
		SolverCategory::Category	category
	)

Choose the approriate scalar product for a solver category.

Todo:

this helper function should be replaced by a proper factory

As there is only one scalar product for each solver category it is possible to choose the appropriate product at compile time.

In each specialization of the this struct there will be a typedef ScalarProduct available the defines the type of the scalar product.
