Detailed Description

template<template< atomicity Ato, typename... Int > class ContainedAccumulator, atomicity Atomicity, typename... Args>
class Gaudi::Accumulators::Buffer< ContainedAccumulator, Atomicity, Args >

Buffer is a non atomic Accumulator which, when it goes out-of-scope, updates the underlying thread-safe Accumulator for all previous updates in one go.

It is templated by the basic accumulator type and has same interface
