Constructor & Destructor Documentation

Ifpack_OverlapFactorObject::Ifpack_OverlapFactorObject ( const Ifpack_OverlapGraph OverlapGraph)

Constructor using Ifpack_OverlapGraph.

Creates an object from the overlap graph.

Parameters
InOverlapGraph - Graph describing the graph that should be used for the factors.
Ifpack_OverlapFactorObject::Ifpack_OverlapFactorObject ( const Epetra_RowMatrix UserMatrix)

Constructor using Epetra_RowMatrix.

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

Parameters
InRowMatrix - An object that has implemented the Epetra_RowMatrix interface.

Member Function Documentation

virtual int Ifpack_OverlapFactorObject::DerivedFactor ( )
protectedpure virtual

Virtual method that computes the factors as needed by the derived class.

This method is called by Factor() afer some safety checks have been performed.

Implemented in Ifpack_CrsIlut.

virtual int Ifpack_OverlapFactorObject::Factor ( )
virtual

Compute factors.

This function computes factors using the method DerivedFactor() that is implemented by the derived class. InitValues() must be called before the factorization can proceed.

virtual int Ifpack_OverlapFactorObject::InitValues ( const Epetra_RowMatrix UserMatrix)
virtual

Initialize values from user matrix A, can be called repeatedly as matrix values change.

Processes matrix values, primarily handling overlap if any has been requested. This method then calls ProcessOverlapMatrix(), a virtual method that must be implemented by any class that derives from this class.

Parameters
InUserMatrix - User matrix to be processed.
virtual int Ifpack_OverlapFactorObject::ProcessOverlapMatrix ( const Epetra_RowMatrix A)
protectedpure virtual

Virtual method that processes the overlap matrix as needed by the derived class.

This method is called by InitValues() afer the user matrix has been distributed to support overlap (if any overlap is requested). ProcessOverlapMatrix must be implemented by any derived class of Ifpack_OverlapFactorObject.

Implemented in Ifpack_CrsIlut.
