Field Summary

Fields

Modifier and Type	Field and Description
static LongInterval[]	EMPTY_ARRAY
static LongInterval	EMPTY_INTERVAL An empty (singleton) interval.
static Comparator<LongInterval>	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<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 −∞.
static Comparator<LongInterval>	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<LongInterval>	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'.
