The natural ordering of durations matches the natural ordering for Double, including non-finite values.
The natural ordering of durations matches the natural ordering for Double, including non-finite values.
AttributesConstruct a Duration from the given length and unit.
Construct a Duration from the given length and unit. Observe that nanosecond precision may be lost if
- the unit is NANOSECONDS - and the length has an absolute value greater than 2^53
Infinite inputs (and NaN) are converted into Duration.Inf, Duration.MinusInf and Duration.Undefined, respectively.
AttributesConstruct a finite duration from the given length and time unit.
Construct a finite duration from the given length and time unit. The unit given is retained throughout calculations as long as possible, so that it can be retrieved later.
AttributesConstruct a finite duration from the given length and time unit, where the latter is looked up in a list of string representation.
Construct a finite duration from the given length and time unit, where the latter is looked up in a list of string representation. Valid choices are:
d, day, h, hr, hour, m, min, minute, s, sec, second, ms, milli, millisecond, µs, micro, microsecond, ns, nano, nanosecond and their pluralized forms (for every but the first mentioned form of each unit, i.e. no "ds", but "days").
Parse String into Duration.
Parse String into Duration. Format is "<length><unit>", where whitespace is allowed before, between and after the parts. Infinities are designated by "Inf", "PlusInf", "+Inf", "Duration.Inf" and "-Inf", "MinusInf" or "Duration.MinusInf". Undefined is designated by "Duration.Undefined".

Construct a possibly infinite or undefined Duration from the given number of nanoseconds.
Construct a possibly infinite or undefined Duration from the given number of nanoseconds.
- Double.PositiveInfinity is mapped to Duration.Inf - Double.NegativeInfinity is mapped to Duration.MinusInf - Double.NaN is mapped to Duration.Undefined - -0d is mapped to Duration.Zero (exactly like 0d)
The semantics of the resulting Duration objects matches the semantics of their Double counterparts with respect to arithmetic operations.
AttributesConstruct a finite duration from the given number of nanoseconds.
Construct a finite duration from the given number of nanoseconds. The result will have the coarsest possible time unit which can exactly express this duration.
AttributesIllegalArgumentException for Long.MinValue since that would lead to inconsistent behavior afterwards (cannot be negated)
Extract length and time unit out of a string, where the format must match the description for apply(String).
Extract length and time unit out of a string, where the format must match the description for apply(String). The extractor will not match for malformed strings or non-finite durations.
AttributesExtract length and time unit out of a duration, if it is finite.
Extract length and time unit out of a duration, if it is finite.
AttributesInfinite duration: greater than any other (apart from Undefined) and not equal to any other but itself.
Infinite duration: greater than any other (apart from Undefined) and not equal to any other but itself. This value closely corresponds to Double.PositiveInfinity, matching its semantics in arithmetic operations.
AttributesInfinite duration: less than any other and not equal to any other but itself.
Infinite duration: less than any other and not equal to any other but itself. This value closely corresponds to Double.NegativeInfinity, matching its semantics in arithmetic operations.
AttributesThe Undefined value corresponds closely to Double.NaN:
The Undefined value corresponds closely to Double.NaN:
- it is the result of otherwise invalid operations - it does not equal itself (according to equals()) - it compares greater than any other Duration apart from itself (for which compare returns 0)
The particular comparison semantics mirror those of Double.NaN.
Use eq when checking an input of a method against this value.
AttributesPreconstructed value of 0.days.
