Detailed Description

Concrete LinearOpBase adapter subclass for Epetra_Operator object.

This subclass can be used to represent the non-transposed operator or transposed operator defined by an Epetra_Operator object. This class can implement apply() using either Epetra_Operator::Apply() or Epetra_Operator::ApplyInverse(). In addition, the user can specify whether adjoints are supported or not.

Partial Automatic Change Propagation: This class shall maintain no state with respect to the values of the internally stored Epetra_Operator object. Therefore, as long as the domain and range maps do not change, the the Epetra_Operator can be changed and this will automatically update *this object. This simplifies some types of update operations. Since this is a simple concrete class, this is harmless. However, if the range and domain maps change, then one must call the this->initialize() function.

Member Function Documentation

void Thyra::EpetraLinearOp::initialize	(	const RCP< Epetra_Operator > &	op,
		EOpTransp	opTrans = `NOTRANS`,
		EApplyEpetraOpAs	applyAs = `EPETRA_OP_APPLY_APPLY`,
		EAdjointEpetraOp	adjointSupport = `EPETRA_OP_ADJOINT_SUPPORTED`,
		const RCP< const VectorSpaceBase< double > > &	range = `Teuchos::null`,
		const RCP< const VectorSpaceBase< double > > &	domain = `Teuchos::null`
	)

Fully initialize.

Parameters

op	[in] The `Epetra_Operator` this `*this` will wrap.
opTrans	[in] If `opTrans==NOTRANS` then `op` will be viewed as `op` and if `opTrans==TRANS` then `op` will be viewed as its transpose `op'` for the behavior of `apply()`.
applyAs	[in] If `applyAs==APPLY_APPLY` then `op->Apply()` will be used and if `applyAs==APPLY_APPLY_INVERSE` then `op->ApplyInverse()` is used instead.
adjointSupport	[in] Determines if it is to be assumed that adjoints are supported on the underlying `Epetra_Operator` object `op`. If `adjointSupport==EPETRA_OP_ADJOINT_SUPPORTED` then `this->opSupported(TRANS)` will return `true`. If `adjointSupport==EPETRA_OP_ADJOINT_UNSUPPORTED` then `this->opSupported(TRANS)` will return `false`.
range	[in] Smart pointer to the range space for the `Epetra_Operator`. The default value is `Teuchos::null` in which case `*this` will allocate a new `SpmdVectorSpace` given range map from `op`. A client may only bother to specify this space if one wants to override the defintion of the scalar product.
domain	[in] Smart pointer to the domain space for the `Epetra_Operator`. The default value is `Teuchos::null` in which case `*this` will allocate a new `DefaultSpmdVectorSpace` given map from `op`. A client may only bother to specify this space if one wants to override the defintion of the scalar product.

Preconditions:

!is_null(op)

Postconditions:

this->epetra_op().get() == op.get()
[range.get() != NULL] this->range().get() == range.get()
[domain.get() != NULL] this->domain().get() == domain.get()
[range.get() == NULL] this->range().get() != NULL
[domain.get() == NULL] this->domain().get() != NULL
this->opSupported(NOTRANS) == true
this->opSupported(TRNAS) == adjointSupport==EPETRA_OP_ADJOINT_SUPPORTED

After this function is called, this will be fully initialized and ready to go.

Definition at line 41 of file Thyra_EpetraLinearOp.cpp.

void Thyra::EpetraLinearOp::partiallyInitialize	(	const RCP< const VectorSpaceBase< double > > &	range,
		const RCP< const VectorSpaceBase< double > > &	domain,
		const RCP< Epetra_Operator > &	op,
		EOpTransp	opTrans = `NOTRANS`,
		EApplyEpetraOpAs	applyAs = `EPETRA_OP_APPLY_APPLY`,
		EAdjointEpetraOp	adjointSupport = `EPETRA_OP_ADJOINT_SUPPORTED`
	)

Partially initialize.

Parameters

range	[in] Smart pointer to the range space for the `Epetra_Operator`.
domain	[in] Smart pointer to the domain space for the `Epetra_Operator`.
op	[in] The `Epetra_Operator` this `*this` will wrap. This object is assumed to not be fully unitialized.
opTrans	[in] If `opTrans==NOTRANS` then `op` will be viewed as `op` and if `opTrans==TRANS` then `op` will be viewed as its transpose `op'` for the behavior of `apply()`.
applyAs	[in] If `applyAs==APPLY_APPLY` then `op->Apply()` will be used and if `applyAs==APPLY_APPLY_INVERSE` then `op->ApplyInverse()` is used instead.
adjointSupport	[in] Determines if it is to be assumed that adjoints are supported on the underlying `Epetra_Operator` object `op`. If `adjointSupport==EPETRA_OP_ADJOINT_SUPPORTED` then `this->opSupported(TRANS)` will return `true`. If `adjointSupport==EPETRA_OP_ADJOINT_UNSUPPORTED` then `this->opSupported(TRANS)` will return `false`.

Preconditions:

!is_null(range)
!is_null(domain)
!is_null(op)

Postconditions:

this->epetra_op().get() == op.get()
[range.get() != NULL] this->range().get() == range.get()
[domain.get() != NULL] this->domain().get() == domain.get()
[range.get() == NULL] this->range().get() != NULL
[domain.get() == NULL] this->domain().get() != NULL
this->opSupported(NOTRANS) == true
this->opSupported(TRNAS) == adjointSupport==EPETRA_OP_ADJOINT_SUPPORTED

After this function is called, only the range and domain spaces will be supported and this must be followed up by a call to setFullyInitialized().

Definition at line 88 of file Thyra_EpetraLinearOp.cpp.

void Thyra::EpetraLinearOp::setFullyInitialized ( bool isFullyInitialized = true )

Set to fully initialized.

In debug mode, asserts will be performed to ensure that everything matches up as it should.

The functions initialize() ore partiallyInitialize() must have been called prior to calling this function.

protectedvirtual

Allocate the domain space of the operator.

Purpose: In TSFExtended, both EpetraLinearOp and EpetraVectorSpace are extended from the Thyra versions by inheritance, and the TSFExtended operator subclasses expect to work with an extended vector space subclass. Thus, it is necessary for the base operator class to never directly allocate vector space objects, and allocation is delegated to a virtual allocator function.

Purpose: In TSFExtended, both EpetraLinearOp and EpetraVectorSpace are extended from the Thyra versions by inheritance, and the TSFExtended operator subclasses expect to work with an extended vector space subclass. Thus, it is necessary for the base operator class to never directly allocate vector space objects, and allocation is delegated to a virtual allocator function.
