Detailed Description

template<typename ValueType = default_precision>
class gko::Composition< ValueType >

The Composition class can be used to compose linear operators op1, op2, ..., opn and obtain the operator op1 * op2 * ... * opn.

All LinOps of the Composition must operate on Dense inputs. For an operator op_k that require an initial guess for their apply, Composition provides either

the output of the previous op_{k+1}->apply if op_k has square dimension
zero if op_k is rectangular as an initial guess.

Composition ensures that all LinOps passed to its constructor use the same executor, and if not, copies the operators to the executor of the first operator.

Template Parameters

ValueType precision of input and result vectors

Constructor & Destructor Documentation

◆ Composition() [1/5]

template<typename ValueType = default_precision>

gko::Composition< ValueType >::Composition ( const Composition< ValueType > & )

Copy-constructs a Composition. This inherits the executor of the input Composition and all of its operators with shared ownership.

◆ Composition() [2/5]

template<typename ValueType = default_precision>

gko::Composition< ValueType >::Composition ( Composition< ValueType > && )

Move-constructs a Composition. This inherits the executor of the input Composition and all of its operators. The moved-from object is empty (0x0 LinOp without operators) afterwards.

◆ Composition() [3/5]

template<typename ValueType = default_precision>

gko::Composition< ValueType >::Composition ( std::shared_ptr< const Executor > exec )

inlineexplicitprotected

Creates an empty operator composition (0x0 operator).

Parameters

exec	Executor associated to the composition

◆ Composition() [4/5]

template<typename ValueType = default_precision>

template<typename Iterator , typename = std::void_t< typename std::iterator_traits<Iterator>::iterator_category>>

gko::Composition< ValueType >::Composition	(	Iterator	begin,
		Iterator	end
	)

inlineexplicitprotected

Creates a composition of operators using the operators in a range.

Template Parameters

Iterator a class representing iterators over the operators of the composition

Parameters

begin	iterator pointing to the first operator
end	iterator pointing behind the last operator

◆ Composition() [5/5]

template<typename ValueType = default_precision>

template<typename... Rest>

gko::Composition< ValueType >::Composition	(	std::shared_ptr< const LinOp >	oper,
		Rest &&...	rest
	)

inlineexplicitprotected

Creates a composition of operators using the specified list of operators.

Template Parameters

Rest	types of trailing parameters

Parameters

oper	the first operator
rest	remaining operators

Member Function Documentation

◆ conj_transpose()

template<typename ValueType = default_precision>

std::unique_ptr< LinOp > gko::Composition< ValueType >::conj_transpose ( ) const

overridevirtual

Returns a LinOp representing the conjugate transpose of the Transposable object.

Returns: a pointer to the new conjugate transposed object

Implements gko::Transposable.

◆ get_operators()

template<typename ValueType = default_precision>

const std::vector< std::shared_ptr< const LinOp > > & gko::Composition< ValueType >::get_operators ( ) const

inlinenoexcept

Returns a list of operators of the composition.

Returns: a list of operators

◆ operator=() [1/2]

template<typename ValueType = default_precision>

Composition & gko::Composition< ValueType >::operator= ( Composition< ValueType > && )

Move-assigns a Composition. The executor is not modified, and the wrapped LinOps are only being cloned if they are on a different executor, otherwise they share ownership. The moved-from object is empty (0x0 LinOp without operators) afterwards.

◆ operator=() [2/2]

template<typename ValueType = default_precision>

Composition & gko::Composition< ValueType >::operator= ( const Composition< ValueType > & )

Copy-assigns a Composition. The executor is not modified, and the wrapped LinOps are only being cloned if they are on a different executor.

◆ transpose()

template<typename ValueType = default_precision>

std::unique_ptr< LinOp > gko::Composition< ValueType >::transpose ( ) const

overridevirtual

Returns a LinOp representing the transpose of the Transposable object.

Returns: a pointer to the new transposed object

Implements gko::Transposable.
