Method Detail

initialize

public void initialize()

Initializes the model by reading the number of particles.

Overrides:

initialize in class AbstractSimulation

doStep

public void doStep()

Does a simulation step and appends data to the views.

Specified by:

doStep in class AbstractAnimation

stop

public void stop()

Prints the LJ model's data after the simulation has stopped.

Overrides:

stop in class AbstractSimulation

startRunning

public void startRunning()

Reads adjustable parameters before the program starts running.

Overrides:

startRunning in class AbstractSimulation

reset

public void reset()

Resets the LJ model to its default state.

Overrides:

reset in class AbstractSimulation

resetData

public void resetData()

Resets the LJ model and the data graphs. This method is invoked using a custom button.

getLoader

public static XML.ObjectLoader getLoader()

Returns an XML.ObjectLoader to save and load data for this program. LJParticle data can now be saved using the Save menu item in the control.

Returns:

the object loader

main

public static void main(java.lang.String[] args)

Starts the Java application.

Parameters:

args - command line parameters
