Modifier and Type  Field and Description 

static Interval[] 
EMPTY_ARRAY 
static Interval 
EMPTY_INTERVAL
An empty (singleton) interval.

static Comparator<Interval> 
ENDS_AFTER
A comparator between intervals defined as follows:
[a..b] is less than [a'..b']
iff the first interval ends after the second one, that is,
iff b' < b.

static Comparator<Interval> 
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<Interval> 
ENDS_BEFORE_OR_IS_SUFFIX
A comparator between intervals defined as follows:
[a..b] is less than [a'..b'] iff
the first interval ends before or is a suffix of the second one, that is,
iff b < b' or b=b' and a' < a.

static Comparator<Interval> 
LENGTH_COMPARATOR
A comparator between intervals based on their length.

static Interval 
MINUS_INFINITY
A singleton located at −∞.

static Comparator<Interval> 
STARTS_AFTER
A comparator between intervals defined as follows:
[a..b] is less than [a'..b']
iff the first interval starts after the second one, that is,
iff a' < a.

static Comparator<Interval> 
STARTS_BEFORE
A comparator between intervals defined as follows:
[a..b] is less than [a'..b']
iff the first interval starts before the second one, that is,
iff a < a'.

static Comparator<Interval> 
STARTS_BEFORE_OR_PROLONGS
A comparator between intervals defined as follows:
[a..b] is less than [a'..b'] iff
the first interval starts before or prolongs the second one, that is,
iff a < a' or a=a' and b' < b.
