public abstract class ObjectAggregationBase<T extends FeatureInputEnergy> extends FeatureSingleObjectFromShared<T>
Calculates a feature for a set of objects using this stack as an energy-stack, and aggregates.

This abstract class extends FeatureSingleObjectFromShared to provide functionality for calculating features on a collection of objects and aggregating the results.
