Examples of org.jgroups.util.RetransmitTable.purge()

org.jgroups.util.RetransmitTable.purge()
Removes all messages less than or equal to seqno from the table. Does this by nulling entire rows in the matrix and nulling all elements < index(seqno) of the first row that cannot be removed @param seqno

            Message msg=table.remove(i);
            assert msg.getObject().equals("hello-" + i);
        }
        System.out.println("table after removal of seqno 60: " + table);


        table.purge(50);
        System.out.println("now triggering a resize() by addition of seqno=120");
        addAndGet(table, 120, "120");
