Constructor Detail

ColtPoisson

public ColtPoisson(ColtPoisson actor)

Constructor method for the ColtPoisson helper.

Parameters:

actor - the associated actor

Method Detail

generateInitializeCode

public java.lang.String generateInitializeCode()
                                        throws IllegalActionException

Generate the code for initializing the random number generator with the seed, if it has been given. A seed of zero is interpreted to mean that no seed is specified. In such cases, a seed based on the current time and this instance of a ColtRandomSource is used to be fairly sure that two identical sequences will not be returned.

Specified by:

generateInitializeCode in interface ComponentCodeGenerator

Overrides:

generateInitializeCode in class ColtRandomSource

Returns:

The initialize code of this actor.

Throws:

IllegalActionException - Not thrown in this class.

getHeaderFiles

public java.util.Set getHeaderFiles()
                             throws IllegalActionException

Get the files needed by the code generated for the ColtPoisson actor.

Specified by:

getHeaderFiles in interface ActorCodeGenerator

Overrides:

getHeaderFiles in class ColtRandomSource

Returns:

A set of Strings that are names of the files needed by the code generated for the ColtPoisson actor.

Throws:

IllegalActionException - Not Thrown in this subclass.

_generateRandomNumber

protected java.lang.String _generateRandomNumber()
                                          throws IllegalActionException

Generate code for producing a new random number.

Specified by:

_generateRandomNumber in class ColtRandomSource

Returns:

The code that produces a new random number.

Throws:

IllegalActionException - Not thrown in this base class.
