Document

Returns an arbitrary ordering over all objects, for which compare(a, b) == 0 implies a == b (identity equality).

Usage

From source file:brooklyn.location.docker.strategy.DepthFirstPlacementStrategy.java

/** Use an arbitrary, but fixed, ordering. */
@Override/* w w  w . j  a va2s .  c  o m*/
public int compare(DockerHostLocation l1, DockerHostLocation l2) {
    return Ordering.arbitrary().compare(l1, l2);
}
