Remarks

This class incrementally recomputes the sum of an AList{T} (or its variants - BList, BDictionary, and BMultiMap).

Public fields
double	Sum => Summary

double	Average => Summary / TotalCountInAttachedLists

Public fields inherited from Loyc.Collections.AListStatisticTrackerBase< K, T, TSummary >
IEnumerable< AListBase< K, T > >	AttachedLists => _roots.Keys

int	TotalCountInAttachedLists => _roots.Sum(pair => pair.Key.Count)

TSummary	Summary => GetSummary()

Public Member Functions
	AListSumTracker (Func< T, double > selector, AListBase< K, T > list=null)

Public Member Functions inherited from Loyc.Collections.AListStatisticTracker< K, T, TSummary >
	AListStatisticTracker (Func< T, TSummary > selector, Func< TSummary[], TSummary > aggregator, TSummary emptyResult, AListBase< K, T > list=null)

	AListStatisticTracker (Func< T, TSummary > selector, Func< TSummary, TSummary, TSummary > aggregator, TSummary emptyResult, AListBase< K, T > list=null)

Public Member Functions inherited from Loyc.Collections.AListStatisticTrackerBase< K, T, TSummary >
TSummary	GetSummary ()

Public Member Functions inherited from Loyc.Collections.Impl.IAListTreeObserver< K, T >
void	Detach (AListBase< K, T > list, AListNode< K, T >?root)
	Called when the observer is being detached from an AList. Detach(), unlike Attach(), is not paired with a call to RootChanged. More...

void	RootChanged (AListBase< K, T > list, AListNode< K, T >?root, bool clear)
	Called when the root of the tree changes, or when the list is cleared. Also called after Attach(), but not after Detach(). More...
