Duration¶

common

class Duration : Comparable<Duration>

A duration of time at nanosecond precision.

For many applications, working with specific units like Hours or Seconds is more efficient and plenty adequate. However, when working with larger durations at sub-second precision, overflow is a very real possibility. Duration is capable of representing fixed, nanosecond-precision durations that span the entire supported time scale, making it more suitable for these use cases.

Functions¶

Name	Summary
compareTo	common `open operator override fun compareTo(other: Duration): Int`
div	common `operator fun div(scalar: Int): Duration` Divides this duration by a scalar value.
equals	common `open operator override fun equals(other: Any?): Boolean`
hashCode	common `open override fun hashCode(): Int`
isNegative	common `fun isNegative(): Boolean` Checks if this duration is negative.
isPositive	common `fun isPositive(): Boolean` Checks if this duration is positive.
isZero	common `fun isZero(): Boolean` Checks if this duration is zero.
minus	common `operator fun minus(days: Days): Duration` `operator fun minus(other: Duration): Duration` `operator fun minus(hours: Hours): Duration` `operator fun minus(microseconds: Microseconds): Duration` `operator fun minus(milliseconds: Milliseconds): Duration` `operator fun minus(minutes: Minutes): Duration` `operator fun minus(nanoseconds: Nanoseconds): Duration` `operator fun minus(seconds: Seconds): Duration`
plus	common `operator fun plus(days: Days): Duration` `operator fun plus(other: Duration): Duration` `operator fun plus(hours: Hours): Duration` `operator fun plus(microseconds: Microseconds): Duration` `operator fun plus(milliseconds: Milliseconds): Duration` `operator fun plus(minutes: Minutes): Duration` `operator fun plus(nanoseconds: Nanoseconds): Duration` `operator fun plus(seconds: Seconds): Duration`
times	common `operator fun times(scalar: Int): Duration` Multiples this duration by a scalar value.
toComponents	common `inline fun <T> toComponents(action: (seconds: Seconds, nanoseconds: Nanoseconds) -> T): T` `inline fun <T> toComponents(action: (minutes: Minutes, seconds: Seconds, nanoseconds: Nanoseconds) -> T): T` `inline fun <T> toComponents(action: (hours: Hours, minutes: Minutes, seconds: Seconds, nanoseconds: Nanoseconds) -> T): T` Breaks this duration down into individual unit components. common `inline fun <T> toComponents(action: (days: Days, hours: Hours, minutes: Minutes, seconds: Seconds, nanoseconds: Nanoseconds) -> T): T` Breaks this duration down into individual unit components, assuming a 24-hour day length.
toComponentValues	common `inline fun <T> toComponentValues(action: (seconds: Long, nanoseconds: Int) -> T): T` `inline fun <T> toComponentValues(action: (minutes: Long, seconds: Int, nanoseconds: Int) -> T): T` `inline fun <T> toComponentValues(action: (hours: Long, minutes: Int, seconds: Int, nanoseconds: Int) -> T): T` Breaks this duration down into individual unit components. common `inline fun <T> toComponentValues(action: (days: Long, hours: Int, minutes: Int, seconds: Int, nanoseconds: Int) -> T): T` Breaks this duration down into individual unit components, assuming a 24-hour day length.
toKotlinDuration	common `fun toKotlinDuration(): Duration` Converts this duration to a kotlin.time.Duration. Since Kotlin's `Duration` type is based on a floating-point number, precision may be lost.
toString	common `open override fun toString(): String`
truncatedTo	common `fun truncatedTo(unit: TimeUnit): Duration` Returns this duration, rounded down to match the precision of a given unit.
unaryMinus	common `operator fun unaryMinus(): Duration`
