Teuchos::RCP< const Tpetra::Map< local_ordinal_type, global_ordinal_type, node_type > > getRangeMap() const
The range Map of this Operator.
OperatorType::local_ordinal_type local_ordinal_type
The type of local indices in the input OperatorType.
A class for wrapping an Operator apply in a Operator.
OperatorType::scalar_type scalar_type
The type of the entries of the input OperatorType.
virtual ~ApplyOp()
Destructor.
Abstract interface for operators (e.g., matrices and preconditioners).
void apply(const Tpetra::MultiVector< Scalar, local_ordinal_type, global_ordinal_type, node_type > &X, Tpetra::MultiVector< Scalar, local_ordinal_type, global_ordinal_type, node_type > &Y, Teuchos::ETransp mode=Teuchos::NO_TRANS, Scalar alpha=Teuchos::ScalarTraits< Scalar >::one(), Scalar beta=Teuchos::ScalarTraits< Scalar >::zero()) const
Compute Y = beta*Y + alpha*Op(A)*X, where Op(A) is either A, , or .
OperatorType::global_ordinal_type global_ordinal_type
The type of global indices in the input OperatorType.
bool hasTransposeApply() const
Whether this Operator&#39;s apply() method can apply the transpose or conjugate transpose.
OperatorType::node_type node_type
The type of the Kokkos Node used by the input OperatorType.
Teuchos::RCP< const OperatorType > operator_
The underlying Operator object.
Teuchos::RCP< const Tpetra::Map< local_ordinal_type, global_ordinal_type, node_type > > getDomainMap() const
The domain Map of this Operator.
ApplyOp(const Teuchos::RCP< const OperatorType > &op)
Constructor.
