public abstract class ColtRandomSource
extends RandomSource

Base class for Colt random sources. This base class manages the choice of random number generator class. When the random number generator class is set for any one actor in a model, it gets set to match in all other actors within the same top-level container (unless this actor is within an EntityLibrary).

Field Detail

generatorClass

public SharedParameter generatorClass

The low-level random number generator (RNG) class name. This is a string that defaults to "DRand". Below are possible values for this parameter and links to pages that define the meaning of the parameter. This is a "shared parameter", which means that changing this parameter in any one actor will cause a similar change to be applied to all other Colt actors within the same top level (unless this is in a library).

"DRand" (Definition)

"MersenneTwister (MT19937)" (Definition)

"Ranecu"" (Definition)

"Ranlux" (Definition)

"Ranmar" (Definition)

_randomNumberGenerator

protected edu.cornell.lassp.houle.RngPack.RandomElement _randomNumberGenerator

The low-level random number generator.

Constructor Detail

ColtRandomSource

public ColtRandomSource(CompositeEntity container,
                        java.lang.String name)
                 throws NameDuplicationException,
                        IllegalActionException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

If the attribute is generatorClass then create the base random number generator.

Overrides:

attributeChanged in class RandomSource

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container (not thrown in this base class).

_createdNewRandomNumberGenerator

protected abstract void _createdNewRandomNumberGenerator()

Method that is called after _randomNumberGenerator is changed.

_createGenerator

protected void _createGenerator()
                         throws IllegalActionException

Create the random number generator using current parameter values.

Overrides:

_createGenerator in class RandomSource

Throws:

IllegalActionException - If thrown while reading the seed Token.
