Detailed Description

Sequential implementation of the Map/reduce pattern.

Function Documentation

template<typename InputIt , typename Result , typename Transformer , typename Combiner >

Result grppi::map_reduce	(	sequential_execution &	,
		InputIt	first,
		InputIt	last,
		Result	identity,
		Transformer &&	transform_op,
		Combiner &&	combine_op
	)

Invoke Map/reduce pattern on a data sequence with sequential execution.

Template Parameters

InputIt	Iterator type used for the input sequence.
Result	Result type of the reduction.
Transformer	Callable type for the transformation operation.
Combiner	Callable type for the combination operation of the reduction.

Parameters

ex	Sequential 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 combination operation.
transf_op	Transformation operation.
combine_op	Combination operation.

Returns

Result of the map/reduce operation.
