Base interface for linear operators that can be accessed as sub-blocks.
virtual bool blockIsConst(const int i, const int j) const =0
Return if the block (i,j) is const only or not.
virtual bool blockExists(const int i, const int j) const =0
Return if the block (i,j) exists or not.
virtual Teuchos::RCP< const ProductVectorSpaceBase< Scalar > > productDomain() const =0
Return the product space for the domain.
virtual Teuchos::RCP< LinearOpBase< Scalar > > getNonconstBlock(const int i, const int j)=0
Return a non-const view of the block (i,j) if it exists.
virtual Teuchos::RCP< const ProductVectorSpaceBase< Scalar > > productRange() const =0
Return the product space for the range.
virtual Teuchos::RCP< const LinearOpBase< Scalar > > getBlock(const int i, const int j) const =0
Return a const view of the block (i,j) if it exists.
Base class for all linear operators.
