Constructor Detail

LoopingThread

protected LoopingThread()

Get an instance of LoopingThread.

LoopingThread

protected LoopingThread(String name)

Get a LoopingThread with a specified name.

LoopingThread

protected LoopingThread(ThreadGroup tg,
                        String name)

Get a looping thread belonging to a specific group and having the specified name.

Method Detail

setMsPerLoop

public void setMsPerLoop(int msPerLoop)

Set the number of milliseconds to sleep during each loop. Default is 5000 (five seconds).

Parameters:

msPerLoop - number of milliseconds to delay between loops

getMsPerLoop

public int getMsPerLoop()

Get the number of milliseconds to sleep during each loop.

Returns:

the number of milliseconds to wait during a loop.

requestStop

public void requestStop()

Request the looping should end.

runLoop

protected abstract void runLoop()

This is the stuff that should happen during each execution of the run loop.

performDelay

protected void performDelay()

Method to pause between loops. This is implemented via wait() so a notify() will cause this object to awaken from its sleep.

run

public void run()

The run loop itself.
