Examples of org.jgroups.util.Scheduler

org.jgroups.util.Scheduler
Implementation of a priority scheduler. The scheduler maintains a queue to the end of which all tasks are added. It continually looks at the first queue element, assigns a thread to it, runs the thread and waits for completion. When a new priority task is added, it will be added to the head of the queue and the scheduler will be interrupted. In this case, the currently handled task is suspended, and the one at the head of the queue handled. This is recursive: a priority task can always be interrupted by another priority task. Resursion ends when no more priority tasks are added, or when the thread pool is exhausted. @author Bela Ban
