java.lang.Objectfr.lifl.jedi.model.interactionSelection.reactiveSelection.WeightedSelectionNature<Element>
public abstract class WeightedSelectionNature<Element>
The weighted selection nature. This provides a tool that makes stochastic selection.
It gives to every element a weight (see getWeightFor(Object)
).
From this weight, it provides to every element an interval included in [0,1[ such that :
Consequently, even if the list of elements is not empty, this selection process might not select an element.
