4. #### implicit object DurationIsOrdered extends Ordering[Duration]

The natural ordering of durations matches the natural ordering for Double, including non-finite values.

5. #### val Inf: Infinite

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.

6. #### val MinusInf: Infinite

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.

7. #### val Undefined: Infinite

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.

8. #### val Zero: FiniteDuration

Preconstructed value of `0.days`.

9. #### def apply(s: String): Duration

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"` and `"-Inf"` or `"MinusInf"`.

Exceptions thrown
NumberFormatException

if format is not parseable

10. #### def apply(length: Long, unit: String): FiniteDuration

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, hour, 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").

11. #### def apply(length: Long, unit: TimeUnit): 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.

12. #### def apply(length: Double, unit: TimeUnit): Duration

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.

Exceptions thrown
IllegalArgumentException

if the length was finite but the resulting duration cannot be expressed as a FiniteDuration

15. #### def create(s: String): Duration

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"` and `"-Inf"` or `"MinusInf"`.

Exceptions thrown
NumberFormatException

16. #### def create(length: Long, unit: String): FiniteDuration

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, hour, 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").

17. #### def create(length: Double, unit: TimeUnit): Duration

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.

IllegalArgumentException

if the length was finite but the resulting duration cannot be expressed as a FiniteDuration

18. #### def create(length: Long, unit: TimeUnit): 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.

22. #### def fromNanos(nanos: Long): FiniteDuration

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.

Exceptions thrown
IllegalArgumentException

for `Long.MinValue` since that would lead to inconsistent behavior afterwards (cannot be negated)

23. #### def fromNanos(nanos: Double): Duration

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.

The semantics of the resulting Duration objects matches the semantics of their Double counterparts with respect to arithmetic operations.

Exceptions thrown
IllegalArgumentException

if the length was finite but the resulting duration cannot be expressed as a FiniteDuration
