const class sys::Duration
sys::Obj sys::Duration
@Serializable { simple=true }
Duration represents a relative duration of time with nanosecond precision.
Also see docLang.
- abs
-
Duration abs()
Absolute value - if this is a negative duration, then return its positive value.
- boot
-
static Duration boot()
Get the system timer at boot time of the Fantom VM.
- clamp
-
Duration clamp(Duration min, Duration max)
Clamp this duration between the min and max. If it's less than min then return min, if it's greater than max return max, otherwise return this duration itself.
- compare
-
virtual override Int compare(Obj obj)
Compare based on nanosecond ticks.
- defVal
-
const static Duration defVal
Default value is 0ns.
- div
-
Divide this by b. Shortcut is a/b.
- divFloat
-
@Operator
Duration divFloat(Float b)Divide this by b. Shortcut is a/b.
- equals
-
virtual override Bool equals(Obj? obj)
Return true if same number nanosecond ticks.
- floor
-
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 its seconds are 0.0. - fromIso
-
static Duration fromIso(Str s, Bool checked := true)
Parse a duration according to ISO 8601. If invalid format and checked is false return null, otherwise throw ParseErr. The following restrictions are enforced:
- Cannot specify a
Y
year orM
month component since it is ambiguous - Only the
S
seconds component may include a fraction - Only nanosecond resolution is supported See
toIso
for example formats.
- Cannot specify a
- fromStr
-
static new fromStr(Str s, Bool checked := true)
Parse a Str into a Duration according to the Fantom 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")
- hash
-
virtual override Int hash()
Return ticks().
- make
-
static new make(Int ticks)
Create a Duration which represents the specified number of nanosecond ticks.
- max
-
Return the maximum duration between this and that.
- maxVal
-
const static Duration maxVal
Max value is equivalent to
make(Int.maxVal)
. - min
-
Return the minimum duration between this and that.
- minVal
-
const static Duration minVal
Min value is equivalent to
make(Int.minVal)
. - minus
-
@Operator
Duration minus(Duration b)Subtract b from this. Shortcut is a-b.
- mult
-
@Operator
Duration mult(Int b)Multiply this with b. Shortcut is a*b.
- multFloat
-
@Operator
Duration multFloat(Float b)Multiply this with b. Shortcut is a*b.
- negate
-
Negative of this. Shortcut is -a.
- now
-
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.
- nowTicks
-
static Int nowTicks()
Convenience for
now.ticks
. - plus
-
@Operator
Duration plus(Duration b)Add this with b. Shortcut is a+b.
- ticks
-
Int ticks()
Return number of nanosecond ticks.
- toCode
-
Str toCode()
Get this Duration as a Fantom code literal.
- toDay
-
Int toDay()
Get this duration in 24 hour days. Any fractional days are truncated with a loss of precision.
- toHour
-
Int toHour()
Get this duration in hours. Any fractional hours are truncated with a loss of precision.
- toIso
-
Str toIso()
Format this duration according to ISO 8601. Also see
fromIso
.Examples:
8ns.toIso => PT0.000000008S 100ms.toIso => PT0.1S (-20sec).toIso => -PT20S 3.5min.toIso => PT3M30S 1day.toIso => PT24H (1day+2hr+3min).toIso => P1DT2H3M
- toLocale
-
Str toLocale()
Return human friendly string representation. TODO: enhance this for pattern
- toMillis
-
Int toMillis()
Get this duration in milliseconds. Any fractional milliseconds are truncated with a loss of precision.
- toMin
-
Int toMin()
Get this duration in minutes. Any fractional minutes are truncated with a loss of precision.
- toSec
-
Int toSec()
Get this duration in seconds. Any fractional seconds are truncated with a loss of precision.
- toStr
-
virtual override Str toStr()
Return string representation of the duration which is a valid duration literal format suitable for decoding via
fromStr
. - uptime
-
static Duration uptime()
Get the duration which has elapsed since the Fantom VM was booted which is
