Class AnimThread

java.lang.Object

  +--AnimThread

class AnimThread

extends java.lang.Object

implements java.lang.Runnable

Thread designed to animate a graph. The parameter t of some function is incremented repeatedly, while the refresh() method of a BaseApplet is called.

Constructor Detail

AnimThread

public AnimThread(TimeDependent fn,
                  BaseApplet applet)

Parameters:

fn - The function whose parameter should be varied

applet - The applet which should be refreshed

Method Detail

run

public void run()

Performs the work of the thread. This method should not be executed directly, but via the start() method.

Specified by:

run in interface java.lang.Runnable

hasStarted

public boolean hasStarted()

Returns:

true if the thread has started, else false

start

public void start()

Begins execution in a separate thread. If the thread was previously kill()ed but has not yet terminated, then that thread may, (at the discretion of the implementation) ignore the kill() request.

isRunning

public boolean isRunning()

Returns:

true if the thread is currently running, else false

kill

public void kill()

Signals that the thread should stop running at the next convenient moment. The thread may increment the time parameter and/or refresh the applet a maximum of one more time before halting.

setRange

public void setRange(double min,
                     double max)

Should be considered deprecated and non-functional; will be removed shortly.

setSpeed

public void setSpeed(double speed)

Sets the ratio between simulation time and real time.

Parameters:

speed - The simulation time increment per real second

setRefreshDelay

public void setRefreshDelay(int delay)

Parameters:

delay - The length of real time (in milliseconds) between each frame of animation
