Detailed Description

template<atomicity Atomicity, typename Arithmetic = double>
struct Gaudi::Accumulators::WeightedSquareAccumulator< Atomicity, Arithmetic >

WeightedSquareAccumulator.

A WeightedSquareAccumulator is an Accumulator storing a weighted sum of squared values. It basically takes a pair (value, weight) as input and sums weight*value*value
