Fan

 

const final class

sys::Duration

sys::Obj
  sys::Duration

Duration represents a relative duration of time with nanosecond precision.

Slots

bootSource

static Duration boot()

Get the system timer at boot time of the Fan VM.

compareSource

override Int compare(Obj obj)

Overrides sys::Obj.compare

Compare based on nanosecond ticks.

divSource

Duration div(Float b)

Divide this by b. Shortcut is a/b.

equalsSource

override Bool equals(Obj? obj)

Overrides sys::Obj.equals

Return true if same number nanosecond ticks.

floorSource

Duration floor(Duration accuracy)

Return a new Duration with this duration's nanosecond ticks truncated according to the specified accuracy. For example floor(1min) will truncate this duration such that it's seconds are 0.0.

fromStrSource

static Duration? fromStr(Str s, Bool checked := true)

Parse a Str into a Duration according to the Fan literal format. If invalid format and checked is false return null, otherwise throw ParseErr. The following suffixes are supported:

ns:   nanoseconds  (x 1)
ms:   milliseconds (x 1,000,000)
sec:  seconds      (x 1,000,000,000)
min:  minutes      (x 60,000,000,000)
hr:   hours        (x 3,600,000,000,000)
day:  days         (x 86,400,000,000,000)

Examples:

Duration.fromStr("4ns")
Duration.fromStr("100ms")
Duration.fromStr("-0.5hr")
hashSource

override Int hash()

Overrides sys::Obj.hash

Return ticks().

makeSource

static Duration make(Int ticks)

Create a Duration which represents the specified number of nanosecond ticks.

minusSource

Duration minus(Duration b)

Subtract b from this. Shortcut is a-b.

multSource

Duration mult(Float b)

Multiply this with b. Shortcut is a*b.

negateSource

Duration negate()

Negative of this. Shortcut is -a.

nowSource

static Duration now()

Get the current value of the system timer. This method returns a relative time unrelated to system or wall-clock time. Typically it is the number of nanosecond ticks which have elapsed since system startup.

plusSource

Duration plus(Duration b)

Add this with b. Shortcut is a+b.

ticksSource

Int ticks()

Return number of nanosecond ticks.

toDaySource

Int toDay()

Get this duration in 24 hour days. Any fractional days are truncated with a loss of precision.

toHourSource

Int toHour()

Get this duration in hours. Any fractional hours are truncated with a loss of precision.

toLocaleSource

Str toLocale()

Return human friendly string representation. TODO: enhance this for pattern

toMillisSource

Int toMillis()

Get this duration in milliseconds. Any fractional milliseconds are truncated with a loss of precision.

toMinSource

Int toMin()

Get this duration in minutes. Any fractional minutes are truncated with a loss of precision.

toSecSource

Int toSec()

Get this duration in seconds. Any fractional seconds are truncated with a loss of precision.

toStrSource

override Str toStr()

Overrides sys::Obj.toStr

Return string representation of the duration which is a valid duration literal format suitable for decoding via fromStr.

uptimeSource

static Duration uptime()

Get the duration which has elapsed since the Fan VM was booted which is now - boot.
