Constructor & Destructor Documentation

Ifpack_OverlapGraph::Ifpack_OverlapGraph const Epetra_CrsGraph UserMatrixGraph,
int  OverlapLevel
 

Constructor using Epetra_CrsGraph.

Creates an Ifpack_OverlapGraph object from the user graph.

Parameters:
In UserMatrixGraph - Graph from user matrix.

Ifpack_OverlapGraph::Ifpack_OverlapGraph const Epetra_RowMatrix UserMatrix,
int  OverlapLevel
 

Constructor using Epetra_RowMatrix.

Creates an Ifpack_OverlapGraph object from the user graph implicitly defined by the Epetra_RowMatrix interface.

Parameters:
In RowMatrix - An object that has implemented the Epetra_RowMatrix interface.


Member Function Documentation

int Ifpack_OverlapGraph::OverlapLevel  )  const [inline]
 

Returns the level of overlap used to create this graph.

The graph created by this class uses a recursive definition 0f overlap. Level one overlap is created by copying all off-processor rows that are reached to be at least one column of the rows that are on processor. Level two overlap is the same process used on the level one graph.
