void	graphUpdate()
void	init() This method initializes the experiment, including the timeline, the random variable graph and table, the record table, and the toolbar containing the scrollbars and label.
void	reset() This method resets the experiment, including the timeline, record table, random variable graph and table.
void	run() This method stops the step process, if necessary, and then calls the usual run method.
void	setDistribution() This method sets the Poisson distribution, when the parameters have changed.
void	stateChanged(javax.swing.event.ChangeEvent e) This method handles the scrollbar events for adjusting the size of the time interval and the rate of the Poisson process.

Method Detail

init

public void init()

This method initializes the experiment, including the timeline, the random variable graph and table, the record table, and the toolbar containing the scrollbars and label.

Overrides:

init in class Experiment

getAppletInfo

public java.lang.String getAppletInfo()

This method returns basic information about the applet, including copyright information, descriptive information, and instructions.

Specified by:

getAppletInfo in interface IExperiment

Overrides:

getAppletInfo in class Experiment

Returns:

applet information

doExperiment

public void doExperiment()

Thie method defines the experiment: the arrivals are generated and tested to see if they belong to the interval [0, t].

Specified by:

doExperiment in interface IExperiment

Overrides:

doExperiment in class Experiment

computeArrivalTimes

public void computeArrivalTimes()
