Package org.opensourcephysics.controls

Class AbstractAnimation

java.lang.Object

org.opensourcephysics.controls.AbstractAnimation

All Implemented Interfaces:

java.lang.Runnable, Animation

Direct Known Subclasses:

AbstractSimulation

public abstract class AbstractAnimation
extends java.lang.Object
implements Animation, java.lang.Runnable

AbstractAnimation is a template for simple animations. Implement the doStep method to create an animation. This method is called from the run method and when the stepAnimation button is pressed.

Method Detail

setControl

public void setControl(Control control)

Sets the Control for this model and initializes the control's values.

Specified by:

setControl in interface Animation

Parameters:

control -

setDelayTime

public void setDelayTime(int delay)

Sets the preferred delay time in ms between animation steps.

Parameters:

delay -

getDelayTime

public int getDelayTime()

Gets the preferred delay time in ms between animation steps.

Returns:

getMainFrame

public OSPFrame getMainFrame()

Gets the main OSPFrame. The main frame will usually exit program when it is closed.

Returns:

OSPFrame

getOSPApp

public OSPApplication getOSPApp()

Gets the main OSPFrame. The main frame will usually exit program when it is closed.

Returns:

OSPFrame

addChildFrame

public void addChildFrame(javax.swing.JFrame frame)

Adds a child frame that depends on the main frame. Child frames are closed when this frame is closed.

Parameters:

frame - JFrame

clearChildFrames

public void clearChildFrames()

Clears the child frames from the main frame.

getChildFrames

public java.util.Collection<javax.swing.JFrame> getChildFrames()

Gets a copy of the ChildFrames collection.

Returns:

Collection

getControl

public Control getControl()

Gets the Control.

Returns:

the control

initializeAnimation

public void initializeAnimation()

Initializes the animation by reading parameters from the control.

Specified by:

initializeAnimation in interface Animation

doStep

protected abstract void doStep()

Does an animation step.

stopAnimation

public void stopAnimation()

Stops the animation. Sets animationThread to null and waits for a join with the animation thread.

Specified by:

stopAnimation in interface Animation

isRunning

public final boolean isRunning()

Determines if the animation is running.

Returns:

boolean

stepAnimation

public void stepAnimation()

Steps the animation.

Specified by:

stepAnimation in interface Animation

startAnimation

public void startAnimation()

Starts the animation. Use this method to start a timer or a thread.

Specified by:

startAnimation in interface Animation

resetAnimation

public void resetAnimation()

Resets the animation to a predefined state.

Specified by:

resetAnimation in interface Animation

run

public void run()

Implementation of Runnable interface. DO NOT access this method directly.

Specified by:

run in interface java.lang.Runnable

getLoader

public static XML.ObjectLoader getLoader()

Returns an XML.ObjectLoader to save and load data for this object.

Returns:

the object loader
