Detailed Description

template<class PB>
class AMDiS::GlobalBasis< PB >

Global basis defined on a pre-basis.

This class is an expansion to Dune::Functions::DefaultGlobalBasis<PB>. It adds a communicator to use the basis in parallel as well as automatic update functionality.

Template Parameters

PB	Pre-basis providing the implementation details

Constructor & Destructor Documentation

GlobalBasis()

GlobalBasis ( std::string const &  name, Grid const &  grid, Args &&...  args  )

inline

Construct this global basis with given name and grid, and constructing a preBasis.

Parameters

name	Name associated with this basis for initfile parameter attachment.
grid	The Grid providing the GridView for this basis
args...	Argument list for PreBasis

This will forward all arguments to the constructor of PreBasis

Member Function Documentation

indexDistribution()

IndexDist const& indexDistribution ( ) const

inline

Return the index distribution.

This provides the means to communicate indices associated to the basis with other processes.

update()

void update ( GridView const &  gv )

inline

Update the stored grid view.

This will update the indexing information of the global basis as well as the communicator. It is called automatically if the grid has changed.
