Detailed Description

template<typename RecordType, typename MathType>
class Mezzanine::WeightedRollingAverage< RecordType, MathType >

A weighted average that does math with every insertion and stores nothing.

This is possibly an optimization over the BufferedRollingAverage. It has not yet been shown whether the amount of memory for each task will significantly affect load times (From RAM to CPU cache) when starting a rolling average, or whether any innaccuracies in sorting using this would outweigh that.

Member Function Documentation

template<typename RecordType , typename MathType >

virtual RecordType Mezzanine::WeightedRollingAverage< RecordType, MathType >::GetAverage ( ) const

inlinevirtual

Get the current rolling average.

Returns

Get the Current Rolling average as a RecordType.

Implements Mezzanine::RollingAverage< RecordType >.

Definition at line 246 of file rollingaverage.h.

template<typename RecordType , typename MathType >

virtual void Mezzanine::WeightedRollingAverage< RecordType, MathType >::Insert ( RecordType  Datum )
