Detailed Description

template<class T, class A, bool mode>
class Dune::RemoteIndexListModifier< T, A, mode >

Modifier for adding and/or deleting remote indices from the remote index list.

In some cases all the information about the indices also present on remote process might already be known. In this case this information can be provided to the RemoteIndices via this modifier. This prevents the global communication needed by a call to RemoteIndices::rebuild.

In some cases it might advisable to run IndicesSyncer::sync afterwards.

Warning

Use with care. If the indices are not consistent afterwards communication attempts might deadlock!

Member Enumeration Documentation

anonymous enum

template<class T , class A , bool mode>

anonymous enum

Enumerator
MODIFYINDEXSET	If true the index set corresponding to the remote indices might get modified. If for example new indices are added to an index set all pointers of the remote indices to the local indices become invalid after ParallelIndexSet::endResize() was called.

Constructor & Destructor Documentation

RemoteIndexListModifier()

template<class T , class A , bool mode>

Dune::RemoteIndexListModifier< T, A, mode >::RemoteIndexListModifier ( )

inline

Default constructor.

Warning

Object is not usable!

Member Function Documentation

insert() [1/2]

template<typename T , typename A , bool mode>

void Dune::RemoteIndexListModifier< T, A, mode >::insert ( const RemoteIndex &  index ) throw ( InvalidPosition )

inline

Insert an index to the list.

Moves to the position where the index fits and inserts it. After the insertion only indices with an bigger global index than the inserted can be inserted.

This method is only available if MODIFYINDEXSET is false.

Parameters

index

The index to insert.

Exceptions

InvalidPosition

Thrown if the index at the current position or the one before has bigger global index than the one to be inserted.

Referenced by Dune::OwnerOverlapCopyCommunication< GlobalIdType, LocalIdType >::OwnerOverlapCopyCommunication().

insert() [2/2]

template<typename T , typename A , bool mode>

void Dune::RemoteIndexListModifier< T, A, mode >::insert ( const RemoteIndex &  index, const GlobalIndex &  global  ) throw ( InvalidPosition )

inline

Insert an index to the list.

Moves to the position where the index fits and inserts it. After the insertion only indices with an bigger global index than the inserted can be inserted.

This method is only available if MODIFYINDEXSET is true.

Parameters

index	The index to insert.
global	The global index of the remote index.

Exceptions

InvalidPosition

Thrown if the index at the current position or the one before has bigger global index than the one to be inserted.

remove()

template<typename T , typename A , bool mode>

bool Dune::RemoteIndexListModifier< T, A, mode >::remove	(	const GlobalIndex &	global	)
throw	(	InvalidPosition
	)

Remove a remote index.

Parameters

global

The global index corresponding to the remote index.

Returns

True If there was a corresponding remote index.

Exceptions

InvalidPostion

If there was an insertion or deletion of a remote index corresponding to a bigger global index before.

References DUNE_THROW.

repairLocalIndexPointers()

template<typename T , typename A , bool mode>

void Dune::RemoteIndexListModifier< T, A, mode >::repairLocalIndexPointers throw ( InvalidIndexSetState )

inline

Repair the pointers to the local index pairs.

Due to adding new indices or/and deleting indices in the index set all pointers to the local index pair might become invalid during ParallelIndexSet::endResize(). This method repairs them.

Exceptions

InvalidIndexSetState

Thrown if the underlying index set is not in ParallelIndexSetState::GROUND mode (only when compiled with DUNE_ISTL_WITH_CHECKING!).
