DateRange

class DateRange(start: Date, endInclusive: Date) : DateDayProgression, Interval<Date> , ClosedRange<Date>

An inclusive range of dates.

Date.MIN and Date.MAX are used as sentinels to indicate an unbounded (ie. infinite) start or end.

Constructors

Functions

asPeriod

common

fun asPeriod(): Period

Converts this range into a Period of the same length.

contains

common

open operator override fun contains(value: Date): Boolean

Checks if this interval contains value.

equals

common

open operator override fun equals(other: Any?): Boolean

hasBoundedEnd

common

open fun hasBoundedEnd(): Boolean

Checks if this interval's end is bounded, meaning it has a finite value.

hasBoundedStart

common

open fun hasBoundedStart(): Boolean

Checks if this interval's start is bounded, meaning it has a finite value.

hashCode

common

open override fun hashCode(): Int

hasUnboundedEnd

common

open override fun hasUnboundedEnd(): Boolean

Checks if this interval's end is unbounded.

hasUnboundedStart

common

open override fun hasUnboundedStart(): Boolean

Checks if this interval's start is unbounded.

isBounded

common

open fun isBounded(): Boolean

Checks if both the start and end of this interval are bounded, meaning it has a finite range.

isEmpty

common

open override fun isEmpty(): Boolean

Checks if this progression is empty.

isUnbounded

common

open fun isUnbounded(): Boolean

Checks if both the start and end of this interval are unbounded, meaning this is an infinite time period in both directions.

iterator

common

open operator override fun iterator(): Iterator<Date>

toString

common

open override fun toString(): String

Converts this range to a string in ISO-8601 extended format.

Properties

endExclusive

common

open override val endExclusive: Date

endInclusive

common

open override val endInclusive: Date

The end of this interval, inclusive.

first

common

open override val first: Date

last

common

open override val last: Date

lengthInDays

common

val lengthInDays: LongDays

The number of days in this range.

lengthInMonths

common

val lengthInMonths: IntMonths

The number of whole months in this range.

lengthInWeeks

common

val lengthInWeeks: LongWeeks

The number of whole weeks in this range.

lengthInYears

common

val lengthInYears: IntYears

start

common

open override val start: Date

The start of this interval, inclusive.

step

common

open override val step: IntDays

Extensions

common

infix fun DateRange.at(zone: TimeZone): ZonedDateTimeInterval

Combines this DateRange with a TimeZone to create a ZonedDateTimeInterval between the start of the first day and the end of the last day in zone.

random

common

fun DateRange.random(): Date

Returns a random date within this range using the default random number generator.

fun DateRange.random(random: Random): Date

Returns a random date within this range using the supplied random number generator.

randomOrNull

common

fun DateRange.randomOrNull(): Date?

Returns a random date within this range using the default random number generator or null if the interval is empty or unbounded.

fun DateRange.randomOrNull(random: Random): Date?

Returns a random date within this range using the supplied random number generator or null if the interval is empty or unbounded.

toInstantIntervalAt

common

fun DateRange.toInstantIntervalAt(zone: TimeZone): InstantInterval

Converts this range to an InstantInterval between the start of the first day and the end of the last day in zone.
