All Implemented Interfaces:
ExtensionPoint, Runnable
Direct Known Subclasses:

public abstract class AsyncPeriodicWork extends PeriodicWork
PeriodicWork that takes a long time to run.

Subclasses will implement the execute(TaskListener) method and can carry out a long-running task. This runs in a separate thread so as not to block the timer thread, and this class handles all those details.
