Package repast.simphony.random

Class DistributionsAdapter

java.lang.Object

cern.colt.PersistentObject

cern.jet.random.AbstractDistribution

repast.simphony.random.DistributionsAdapter

All Implemented Interfaces:

cern.colt.function.DoubleFunction, cern.colt.function.IntFunction, Serializable, Cloneable

Direct Known Subclasses:

Lambda

public class DistributionsAdapter
extends cern.jet.random.AbstractDistribution

A wrapper around the Distributions class. Instances of this class will implement the nextMethod and most likely have it delegate to some specific nextXYZ method. For instance, the Lambda subclass delegates to the nextLambda method.

This class's nextDouble() method always throws an UnsupportedOperationException.
