Detailed Description

template<int dim, int spacedim = dim>
class internal::parallel::shared::TemporarilyRestoreSubdomainIds< dim, spacedim >

This class temporarily modifies the subdomain ID of all active cells to their respective "true" owner.

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

The TemporarilyRestoreSubdomainIds class should only be used for temporary read-only purposes. For example, whenever your implementation requires to treat artificial cells temporarily as locally relevant to access their dof indices.

This class has effect only if artificial cells are allowed. Without artificial cells, the current subdomain IDs already correspond to the true subdomain IDs. See the glossary for more information about artificial cells.

Constructor & Destructor Documentation

TemporarilyRestoreSubdomainIds()

template<int dim, int spacedim>

internal::parallel::shared::TemporarilyRestoreSubdomainIds< dim, spacedim >::TemporarilyRestoreSubdomainIds

(

const Triangulation< dim, spacedim > &

tria

)

Constructor.

Stores the subdomain ID of all active cells if the provided Triangulation is of type parallel::shared::Triangulation.

Replaces them by their true subdomain ID equivalent.

Definition at line 474 of file shared_tria.cc.

~TemporarilyRestoreSubdomainIds()

template<int dim, int spacedim>

internal::parallel::shared::TemporarilyRestoreSubdomainIds< dim, spacedim >::~TemporarilyRestoreSubdomainIds

Destructor.

Returns the subdomain ID of all active cells on the parallel::shared::Triangulation into their previous state.
