const Kokkos::View<const panzer::LocalOrdinal*,Kokkos::LayoutRight,PHX::Device> panzer::GlobalIndexer::getElementLIDs ( panzer::LocalOrdinal  localElmtId) const
inline

Access the local IDs for an element. The local ordering is according to the getOwnedAndGhostedIndices method.

Definition at line 221 of file Panzer_GlobalIndexer.hpp.

const Kokkos::View<const panzer::LocalOrdinal**,Kokkos::LayoutRight,PHX::Device> panzer::GlobalIndexer::getLIDs ( ) const
inline

Return all the element LIDS for a given indexer

Definition at line 226 of file Panzer_GlobalIndexer.hpp.

template<typename ArrayT >
void panzer::GlobalIndexer::getElementLIDs ( PHX::View< const int * >  cellIds,
ArrayT  lids,
const int  num_dofs = 0 
) const
inline

Access the local IDs for an element. The local ordering is according to the getOwnedAndGhostedIndices method. Note

Parameters
cellIds[in] The list of cells we require LIDs for
lids[in/out] View to fill with LIDs. extent(1) MUST be sized correctly if num_dofs is not provided.
num_dofs[in] (optional) Number of DOFs in the current element block.

NOTE: The internal array (global_lids/localIDs_k_) is sized for the max dofs across all element blocks in the dof manager. The copy needs the actual number of dofs in the particular element block to fill correctly. Either the caller must supply num_dofs or the lids.extent(1) must be sized correctly for the number of DOFs in the element block. We don't want to search on the element internally to find the element block as this will impact performance.

Definition at line 246 of file Panzer_GlobalIndexer.hpp.

virtual int panzer::GlobalIndexer::getElementBlockGIDCount ( const std::string &  blockId) const
pure virtual

How many GIDs are associated with each element in a particular element block.

This is a per-element count. If you have a quad element with two piecewise bi-linear fields this method returns 8.

Implemented in panzer::BlockedDOFManager, panzer::DOFManager, and panzer::Filtered_GlobalIndexer.

virtual Teuchos::RCP<const ConnManager> panzer::GlobalIndexer::getConnManager ( ) const
pure virtual

Returns the connection manager currently being used.

Implemented in panzer::BlockedDOFManager, panzer::Filtered_GlobalIndexer, and panzer::DOFManager.

void panzer::GlobalIndexer::buildLocalIds ( )
inlineprotected

This method is used by derived classes to the construct the local IDs from the getOwnedAndGhostedIndices method.

Definition at line 300 of file Panzer_GlobalIndexer.hpp.

void panzer::GlobalIndexer::buildLocalIdsFromOwnedElements ( std::vector< std::vector< panzer::LocalOrdinal > > &  localIDs) const
inlineprotected

This method is used by derived classes to the construct the local IDs from the getOwnedAndGhostedIndices method.

Definition at line 357 of file Panzer_GlobalIndexer.hpp.

void panzer::GlobalIndexer::setLocalIds ( const std::vector< std::vector< panzer::LocalOrdinal > > &  localIDs)
inlineprotected

This method provides some capability to set the local IDs externally without using the default buildLocalIds. The point is that we want to keep "getElementLIDs" access exteremly fast.

Definition at line 321 of file Panzer_GlobalIndexer.hpp.

void panzer::GlobalIndexer::shareLocalIDs ( const GlobalIndexer &  src)
inlineprotected

Access internal state and share the local ID fields. This allows decorators classes to be defined and still not loose the performance benefit of the fast getElementLIDs methods. Note that this copies from a distinct UGI into this object.
