Member Function Documentation

int fei::Graph_Impl::addIndices ( int  row,
int  len,
const int *  indices 
) [virtual]

Add indices to a specified row of the table

Implements fei::Graph.

Definition at line 54 of file fei_Graph_Impl.cpp.

int fei::Graph_Impl::addSymmetricIndices ( int  numIndices,
int *  indices,
bool  diagonal = false 
) [virtual]

Add a symmetric block of indices. The array of indices will serve as both row-numbers, and as column-numbers in those rows.

Implements fei::Graph.

Definition at line 70 of file fei_Graph_Impl.cpp.

int fei::Graph_Impl::gatherFromOverlap (  )  [virtual]

gather all remotely-owned table portions to owning processors

Implements fei::Graph.

Definition at line 191 of file fei_Graph_Impl.cpp.

table_type* fei::Graph_Impl::getLocalGraph (  )  [inline, virtual]

Retrieve the local portion of the graph. i.e., The rows which correspond to locally-owned IDs.

Implements fei::Graph.

Definition at line 46 of file fei_Graph_Impl.hpp.

std::vector<remote_table_type*>& fei::Graph_Impl::getRemoteGraph (  )  [inline, virtual]

Retrieve the remotely-owned portion of the graph.

Implements fei::Graph.

Definition at line 52 of file fei_Graph_Impl.hpp.

int fei::Graph_Impl::writeLocalGraph ( FEI_OSTREAM &  os,
bool  debug = false,
bool  prefixLinesWithPoundSign = true 
) [virtual]

Write locally-owned portion of the graph to a specified ostream.

Implements fei::Graph.

Definition at line 152 of file fei_Graph_Impl.cpp.

int fei::Graph_Impl::writeRemoteGraph ( FEI_OSTREAM &  os  )  [virtual]

Write remotely-owned portion of the graph to a specified ostream.

Implements fei::Graph.

Definition at line 181 of file fei_Graph_Impl.cpp.

int fei::Graph_Impl::getNumLocalRows (  ) 

Get the number of locally-owned rows.

Definition at line 303 of file fei_Graph_Impl.cpp.

int fei::Graph_Impl::getNumLocalNonzeros (  )  const

Get the number of nonzeros in the locally-owned portion of the graph.

Definition at line 311 of file fei_Graph_Impl.cpp.

int fei::Graph_Impl::getLocalRowLength ( int  row  ) 

Get the length of a specified locally-owned row.

Definition at line 292 of file fei_Graph_Impl.cpp.
