Detailed Description

template<typename T, typename U>
class EpetraExt::Transform< T, U >

Base Class for all Epetra Transform Operators.

This is the abstract definition for all Epetra Transform Operators. Depending on the type of Transform, several specializations are available: Structural, SameType, InPlace, View.

Member Function Documentation

template<typename T, typename U> virtual NewTypeRef EpetraExt::Transform< T, U >::operator() (  OriginalTypeRef  orig  )  [pure virtual]

Analysis of transform operation on original object and construction of new object. Preconditions: Invariants: Postconditions: Returns: Returns a pointer to the newly created object of type NewTypeRef. The Transform object maintains ownership of this new object and deletes as a part of it's destruction. Implemented in EpetraExt::LinearProblem_BlockJacobi, EpetraExt::CrsGraph_BTF, EpetraExt::CrsMatrix_BTF, EpetraExt::LinearProblem_BTF, EpetraExt::CrsGraph_MapColoringIndex, EpetraExt::CrsGraph_AMD, EpetraExt::LinearProblem_GraphTrans, EpetraExt::LinearProblem_MatrixTrans, EpetraExt::CrsGraph_Overlap, EpetraExt::CrsMatrix_Reindex, EpetraExt::LinearProblem_Reindex, EpetraExt::MultiVector_Reindex, EpetraExt::CrsMatrix_SolverMap, EpetraExt::LinearProblem_SolverMap, EpetraExt::LinearProblem_StaticCondensation, EpetraExt::CrsMatrix_SubCopy, EpetraExt::CrsGraph_SymmRCM, EpetraExt::CrsGraph_Transpose, EpetraExt::RowMatrix_Transpose, EpetraExt::CrsGraph_View, EpetraExt::CrsMatrix_View, EpetraExt::MultiVector_View, and EpetraExt::Zoltan_CrsGraph.

template<typename T, typename U> virtual bool EpetraExt::Transform< T, U >::fwd (   )  [pure virtual]

Forward transfer of data from orig object input in the operator() method call to the new object created in this same call. Returns true is operation is successful. Preconditions: Invariants: Postconditions: Implemented in EpetraExt::LinearProblem_BlockJacobi, EpetraExt::CrsMatrix_BTF, EpetraExt::LinearProblem_BTF, EpetraExt::LinearProblem_CrsSingletonFilter, EpetraExt::CrsMatrix_Dirichlet, EpetraExt::Vector_Dirichlet, EpetraExt::LinearProblem_GraphTrans, EpetraExt::LinearProblem_MatrixTrans, EpetraExt::LinearProblem_Scale, EpetraExt::LinearProblem_StaticCondensation, EpetraExt::CrsMatrix_SubCopy, EpetraExt::StructuralTransform< T, U >, EpetraExt::StructuralSameTypeTransform< T >, EpetraExt::ViewTransform< T >, EpetraExt::Transform_Composite< T >, EpetraExt::RowMatrix_Transpose, EpetraExt::StructuralTransform< Epetra_CrsGraph, Epetra_MapColoring >, EpetraExt::StructuralTransform< Epetra_CrsGraph, std::vector< Epetra_IntVector > >, EpetraExt::StructuralSameTypeTransform< Epetra_LinearProblem >, EpetraExt::StructuralSameTypeTransform< Epetra_CrsMatrix >, EpetraExt::StructuralSameTypeTransform< Epetra_CrsGraph >, EpetraExt::ViewTransform< Epetra_LinearProblem >, EpetraExt::ViewTransform< Epetra_CrsMatrix >, EpetraExt::ViewTransform< Epetra_CrsGraph >, and EpetraExt::ViewTransform< Epetra_MultiVector >.

template<typename T, typename U> virtual bool EpetraExt::Transform< T, U >::rvs (   )  [pure virtual]

Reverse transfer of data from new object created in the operator() method call to the orig object input to this same method. Returns true if operation is successful. Preconditions: Invariants: Postconditions: Implemented in EpetraExt::LinearProblem_BlockJacobi, EpetraExt::CrsMatrix_BTF, EpetraExt::LinearProblem_BTF, EpetraExt::LinearProblem_CrsSingletonFilter, EpetraExt::CrsMatrix_Dirichlet, EpetraExt::Vector_Dirichlet, EpetraExt::LinearProblem_GraphTrans, EpetraExt::LinearProblem_MatrixTrans, EpetraExt::LinearProblem_Scale, EpetraExt::LinearProblem_StaticCondensation, EpetraExt::CrsMatrix_SubCopy, EpetraExt::StructuralTransform< T, U >, EpetraExt::StructuralSameTypeTransform< T >, EpetraExt::ViewTransform< T >, EpetraExt::Transform_Composite< T >, EpetraExt::RowMatrix_Transpose, EpetraExt::StructuralTransform< Epetra_CrsGraph, Epetra_MapColoring >, EpetraExt::StructuralTransform< Epetra_CrsGraph, std::vector< Epetra_IntVector > >, EpetraExt::StructuralSameTypeTransform< Epetra_LinearProblem >, EpetraExt::StructuralSameTypeTransform< Epetra_CrsMatrix >, EpetraExt::StructuralSameTypeTransform< Epetra_CrsGraph >, EpetraExt::ViewTransform< Epetra_LinearProblem >, EpetraExt::ViewTransform< Epetra_CrsMatrix >, EpetraExt::ViewTransform< Epetra_CrsGraph >, and EpetraExt::ViewTransform< Epetra_MultiVector >.

template<typename T, typename U> bool EpetraExt::Transform< T, U >::analyze (  OriginalTypeRef  orig  )  [virtual]

Initial analysis phase of transform. Returns true if the transform is possible allowing methods construct(), fwd() and rvs() to be successfully utilized. Preconditions: Invariants: Postconditions: The default implementation calls method operator() and stores the resulting object in an internal attribute newObj_.

template<typename T, typename U> Transform< T, U >::NewTypeRef EpetraExt::Transform< T, U >::construct (   )  [virtual]

Construction of new object as a result of the transform. Preconditions: Invariants: Postconditions: The default implementation returns internal attribute newObj_. Reimplemented in EpetraExt::LinearProblem_CrsSingletonFilter.

template<typename T, typename U> bool EpetraExt::Transform< T, U >::isConstructed (   )  [virtual]

Check for whether transformed object has been constructed. Preconditions: Invariants: Postconditions: The default implementation returns true if newObj_ != 0.
