Examples of org.jgroups.protocols.pbcast.CoordGmsImpl$MergeTask

kalashnikov.dmitry.lab3.MergeTask
Starts the merge protocol (only run by the merge leader). Essentially sends a MERGE_REQ to all coordinators of all subgroups found. Each coord receives its digest and view and returns it. The leader then computes the digest and view for the new group from the return values. Finally, it sends this merged view/digest to all subgroup coordinators; each coordinator will install it in their subgroup.

public class MergeTaskTest {
    @Test
    public void testNormalMerge() throws Exception {
        int[] first = new int[]{1, 5, 20, 40};
        int[] second = new int[]{0, 9, 20};
        MergeTask mt = new MergeTask(first, second);
        Assert.assertArrayEquals(new int[]{0, 1, 5, 9, 20, 20, 40}, mt.call());
