Examples of org.jgroups.util.TimeScheduler$TaskQueue

org.jgroups.util.TimeScheduler
The task queue used by the scheduler. Tasks are ordered in increasing order of their next execution time

    static final double       PERCENTAGE_OFF=1.3; // how much can expected xmit_timeout and real timeout differ to still be okay ?
    final Map<Long,Entry>     msgs=new ConcurrentHashMap<Long,Entry>(); // keys=seqnos (Long), values=Entries


    @DataProvider(name="provider")
    Object[][] provider() {
        final TimeScheduler timer=new DefaultTimeScheduler(10);
        return new Object[][] {
                {timer,
                 new AckSenderWindow(new MyRetransmitCommand(), new StaticInterval(xmit_timeouts), timer)}
        };
