Method Detail

setPeriodicTask

public void setPeriodicTask(Runnable task)

Description copied from interface: PeriodicRunner

Specify the task that this PeriodicRunner should run periodically. The specified task will not be run until after the PeriodicRunner.start() method has been called.

Specified by:

setPeriodicTask in interface PeriodicRunner

Parameters:

task - The task to run periodically.

start

public void start()

Set an internal flag saying that this runner is in the started state.

Specified by:

start in interface PeriodicRunner

Throws:

IllegalStateException - if no task has been provided.

stop

public void stop()

Set an internal flag saying that this runner is not in the started state.

Specified by:

stop in interface PeriodicRunner

Throws:

IllegalStateException - if the task is already not in the started state.

runOnce

public void runOnce()

Simulate the periodic timer firing and running the Runnable task. This will invoke the specified task once.

This will also verify that this runner is in the started state: that is, that the start() method has been called more recently than the last call to stop(), if any.

Throws:

IllegalStateException - if this runner is not in the started state.
