Detailed Description

template<class Value>
class std::inner_product_detail::reduce_value_policy< Value >

reduce value policy for a C++14 compliant implementation

Template Parameters

Value

accumulator value type

This reduce value policy has an access function that does not std::move the accumulator, it simply provides a reference. The assign function is equivalent to operator=.

The policy value is simply Value unchanged.
