static LongInterval EMPTY_INTERVAL
          An empty (singleton) interval.
static Comparator<LongInterval> ENDS_AFTER

static Comparator<LongInterval> ENDS_BEFORE
          A comparator between intervals defined as follows: [a..b] is less than [a'..b'] iff the first interval ends before the second one, that is, iff b' > b.
static Comparator<LongInterval> LENGTH_COMPARATOR
          A comparator between intervals based on their length.
static LongInterval MINUS_INFINITY
          A singleton located at −&infty;.
