Concrete methods
Construct 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.
- Throws:
- IllegalArgumentException
if the length was finite but the resulting duration cannot be expressed as a FiniteDuration

Construct 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.

- Duration.scala
Construct 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 ", 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".
- Throws:
- NumberFormatException
if format is not parsable

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.
- Throws:
- IllegalArgumentException

Construct 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.
- Throws:
- IllegalArgumentException
for
Long.MinValuesince 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.

Concrete fields
Infinite 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.
- Source:
- Duration.scala
Infinite 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.
- Source:
- Duration.scala
The 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.
