public class ColtPoissonSlow
- extends ColtRandomSource
Produce a random sequence with a PoissonSlow distribution. On each
iteration, a new random number is produced. The output port is of
type DoubleToken. The values that are generated are independent
and identically distributed with the mean and the standard
deviation given by parameters. In addition, the seed can be
specified as a parameter to control the sequence that is generated.
This actor instantiates a
cern.jet.random.PoissonSlow object with
a mean of 1.0.

mean
public PortParameter mean
- mean.
This has type double with default value 1.0.
_current
private int _current
- The random number for the current iteration.
_generator
private cern.jet.random.PoissonSlow _generator
- The random number generator.
ColtPoissonSlow
public ColtPoissonSlow(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.
fire
public void fire()
throws IllegalActionException
- Send a random number with a PoissonSlow distribution to the output.
This number is only changed in the prefire() method, so it will
remain constant throughout an iteration.
- Specified by:
fire
in interface Executable
- Overrides:
fire
in class RandomSource
- Throws:
IllegalActionException
- If there is no director.
_createdNewRandomNumberGenerator
protected void _createdNewRandomNumberGenerator()
- Method that is called after _randomNumberGenerator is changed.
- Specified by:
_createdNewRandomNumberGenerator
in class ColtRandomSource
_generateRandomNumber
protected void _generateRandomNumber()
throws IllegalActionException
- Generate a new random number.
- Specified by:
_generateRandomNumber
in class RandomSource
- Throws:
IllegalActionException
- If parameter values are incorrect.
