Detailed Description

template<int dim, int spacedim = dim>
class parallel::distributed::TemporarilyMatchRefineFlags< dim, spacedim >

This class temporarily modifies the refine and coarsen flags of all active cells to match the p4est oracle.

The modification only happens on parallel::distributed::Triangulation objects, and persists for the lifetime of an instantiation of this class.

The TemporarilyMatchRefineFlags class should only be used in combination with the Triangulation::Signals::post_p4est_refinement signal. At this stage, the p4est oracle already has been refined, but the triangulation is still unchanged. After the modification, all refine and coarsen flags describe how the traingulation will actually be refined.

The use of this class is demonstrated in step-75.

Constructor & Destructor Documentation

TemporarilyMatchRefineFlags()

template<int dim, int spacedim>

parallel::distributed::TemporarilyMatchRefineFlags< dim, spacedim >::TemporarilyMatchRefineFlags

(

::Triangulation< dim, spacedim > &

tria

)

Constructor.

Stores the refine and coarsen flags of all active cells if the provided Triangulation is of type parallel::distributed::Triangulation.

Adjusts them to be consistent with the p4est oracle.

Definition at line 3571 of file tria.cc.

~TemporarilyMatchRefineFlags()

template<int dim, int spacedim>

parallel::distributed::TemporarilyMatchRefineFlags< dim, spacedim >::~TemporarilyMatchRefineFlags

Destructor.

Returns the refine and coarsen flags of all active cells on the parallel::distributed::Triangulation into their previous state.
