template<class Scalar >
virtual Teuchos::RCP<const ProductVectorSpaceBase<Scalar> > Thyra::BlockedLinearOpBase< Scalar >::productRange ( ) const
pure virtual

Return the product space for the range.

A return value of return.get()==NULL is an indication that *this is not fully initialized.

Implemented in Thyra::DefaultBlockedTriangularLinearOpWithSolve< Scalar >, and Thyra::DefaultBlockedLinearOp< Scalar >.

template<class Scalar >
virtual Teuchos::RCP<const ProductVectorSpaceBase<Scalar> > Thyra::BlockedLinearOpBase< Scalar >::productDomain ( ) const
pure virtual

Return the product space for the domain.

A return value of return.get()==NULL is an indication that *this is not fully initialized.

Implemented in Thyra::DefaultBlockedTriangularLinearOpWithSolve< Scalar >, and Thyra::DefaultBlockedLinearOp< Scalar >.

template<class Scalar >
virtual bool Thyra::BlockedLinearOpBase< Scalar >::blockExists ( const int  i,
const int  j 
) const
pure virtual

Return if the block (i,j) exists or not.

Parameters
i[in] Zero-based index for the block row.
j[in] Zero-based index for the block column.

Preconditions:

Implemented in Thyra::DefaultBlockedTriangularLinearOpWithSolve< Scalar >, and Thyra::DefaultBlockedLinearOp< Scalar >.

template<class Scalar >
virtual bool Thyra::BlockedLinearOpBase< Scalar >::blockIsConst ( const int  i,
const int  j 
) const
pure virtual

Return if the block (i,j) is const only or not.

Parameters
i[in] Zero-based index for the block row.
j[in] Zero-based index for the block column.

Preconditions:

Implemented in Thyra::DefaultBlockedTriangularLinearOpWithSolve< Scalar >, and Thyra::DefaultBlockedLinearOp< Scalar >.

template<class Scalar >
virtual Teuchos::RCP<LinearOpBase<Scalar> > Thyra::BlockedLinearOpBase< Scalar >::getNonconstBlock ( const int  i,
const int  j 
)
pure virtual

Return a non-const view of the block (i,j) if it exists.

Parameters
i[in] Zero-based index for the block row.
j[in] Zero-based index for the block column.

Preconditions:

Postconditions:

  • [this->blockExists(i,j)==true] return.get()!=NULL
  • [this->blockExists(i,j)==false] return.get()==NULL

Implemented in Thyra::DefaultBlockedTriangularLinearOpWithSolve< Scalar >, and Thyra::DefaultBlockedLinearOp< Scalar >.

template<class Scalar >
virtual Teuchos::RCP<const LinearOpBase<Scalar> > Thyra::BlockedLinearOpBase< Scalar >::getBlock ( const int  i,
const int  j 
) const
pure virtual

Return a const view of the block (i,j) if it exists.

Parameters
i[in] Zero-based index for the block row.
j[in] Zero-based index for the block column.
