Functions¶

Name	Summary
component1	common `operator fun component1(): Years`
component2	common `operator fun component2(): Months`
component3	common `operator fun component3(): Days`
copy	common `fun copy(years: Years = this.years, months: Months = this.months, days: Days = this.days): Period` Returns a new Period, replacing the years, months, and days components with new values, as desired
equals	common `open operator override fun equals(other: Any?): Boolean`
hashCode	common `open override fun hashCode(): Int`
isNegative	common `fun isNegative(): Boolean` Checks if any component of this period is negative.
isZero	common `fun isZero(): Boolean` Checks if this period is zero.
minus	common `operator fun minus(days: Days): Period` `operator fun minus(months: Months): Period` `operator fun minus(weeks: Weeks): Period` `operator fun minus(years: Years): Period` common `operator fun minus(other: Period): Period` Subtracts each component of another period from this period.
normalized	common `fun normalized(): Period` Normalizes the number of years and months such that "1 year, 15 months" becomes "2 years, 3 months". Only the months and years components are combined. Days are never adjusted.
plus	common `operator fun plus(days: Days): Period` `operator fun plus(months: Months): Period` `operator fun plus(weeks: Weeks): Period` `operator fun plus(years: Years): Period` common `operator fun plus(other: Period): Period` Adds each component of another period to each component of this period.
times	common `operator fun times(scalar: Int): Period` `operator fun times(scalar: Long): Period` Multiplies each component of this period by a scalar value.
toString	common `open override fun toString(): String` Returns an ISO-8601 duration representation, such as "P1Y10M3D".
unaryMinus	common `operator fun unaryMinus(): Period` Reverses the sign of each component in the period.

Properties¶

days	common `val days: Days` The number of days in this period.
months	common `val months: Months` The number of months in this period.
totalMonths	common `val totalMonths: Months` The total number of months in this period, including years.
years	common `val years: Years` The number of years in this period.

Extensions¶

Name	Summary
