static class	ClusterEvent.ReachableDataCenter$
static class	ClusterEvent.ReachableMember	A member is considered as reachable by the failure detector after having been unreachable.
static class	ClusterEvent.ReachableMember$
static class	ClusterEvent.RoleLeaderChanged	First member (leader) of the members within a role set (in the same data center as this node, if data centers are used) changed.
static class	ClusterEvent.RoleLeaderChanged$
static class	ClusterEvent.SeenChanged$
