Template Parameters

Identity	Type of the identity value used by the combiner.
Generator	Callable type used for generating data items.
Combiner	Callable type used for data items combination.
Consumer	Callable type used for consuming data items.

Parameters

ex	Polymorphic parallel execution policy object.
window_size	Number of consecutive items to be reduced.
offset	Number of items after of which a new reduction is started.
identity	Identity value for the combination.
generate_op	Generation operation.
combine_op	Combination operation.
consume_op	Consume operation.
