All Implemented Interfaces:

ElementSelectionNature<Element>

public class RandomSelectionNature<Element>
extends java.lang.Object
implements ElementSelectionNature<Element>

The random selection nature.

This provides a tool to select an element at random among a list of elements.

This class has 3 static values, corresponding to the 3 possible random selections (random selection on RealizableTuples, on AbstractInteraction or on Target Agent).

Random numbers are provided by the SimulationProperties class.
