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.
