Interface for applyinng the Reduce pattern.

Function Documentation

reduce() [1/2]

template<typename Execution , typename InputIt , typename Result , typename Combiner , requires_iterator< InputIt > = 0>

auto grppi::reduce	(	const Execution &	ex,
		InputIt	first,
		InputIt	last,
		Result &&	identity,
		Combiner &&	combine_op
	)

Invoke Reduce pattern with identity value on a data sequence with sequential execution.

Template Parameters

Execution	Execution type.
InputIt	Iterator type used for input sequence.
Result	Type for the identity value.
Combiner	Callable type for the combiner operation.

Parameters

ex	Execution policy object.
first	Iterator to the first element in the input sequence.
last	Iterator to one past the end of the input sequence.
identity	Identity value for the combiner operation.
combiner_op	Combiner operation for the reduction.

Returns

The result of the reduction.

reduce() [2/2]

template<typename Execution , typename InputIt , typename Result , typename Combiner , requires_iterator< InputIt > = 0>

auto grppi::reduce	(	const Execution &	ex,
		InputIt	first,
		std::size_t	size,
		Result &&	identity,
		Combiner &&	combine_op
	)

Invoke Reduce pattern with identity value on a data sequence with sequential execution.

Template Parameters

Execution	Execution type.
InputIt	Iterator type used for input sequence.
Result	Type for the identity value.
Combiner	Callable type for the combiner operation.

Parameters

ex	Execution policy object.
first	Iterator to the first element in the input sequence.
size	Size of the input sequence to be process.
identity	Identity value for the combiner operation.
combiner_op	Combiner operation for the reduction.

Returns

The result of the reduction.
