DynamicYearMonthLocalizer

class DynamicYearMonthLocalizer(options: DynamicYearMonthOptions = DynamicYearMonthOptions(), locale: PlatformLocale = getDefaultLocale()) : PolyglotReferenceDateTimeLocalizer<YearMonth> (source)

Localizes a YearMonth dynamically (either absolute or relative to a Zoned<Instant> reference point).

This class chooses between formatting with a RelativeYearMonthLocalizer (if the difference is within the configured range), or falls back to absolute formatting via YearMonthLocalizer.

Create once and re-use for localizing multiple values with the same options. Use YearMonth.localizeDynamic or YearMonth.localizeDynamicAsFlow for one-off localizations.

Examples:

last month
1 month ago
in 5 mo
07/2026
July 2026

Functions

localize

open override fun localize(value: YearMonth, reference: Zoned<Instant>): TickingValue<String>

localizeAsFlow

fun <T, R> PolyglotReferenceValueLocalizer<T, R>.localizeAsFlow(value: T, clock: Flow<ClockWrapper> = SYSTEM_CLOCK, timeZone: Flow<TimeZone> = SYSTEM_TIMEZONE, maxTick: Duration? = null): Flow<R>

Localizes value by using the given clock's Clock.now and timeZone flows as a reference point and returns a Flow that emits updated values based on the underlying TickingValue.nextTick. This function assumes that each Clock emitted by the clock flow moves forward linearly.

localizeNow

fun <T, R> PolyglotReferenceValueLocalizer<T, R>.localizeNow(value: T, clock: Clock = Clock.System, timeZone: TimeZone = TimeZone.currentSystemDefault()): TickingValue<R>

Localizes value by using the given clock's Clock.now and timeZone as a reference point, rather than passing the reference explicitly.

map

fun <T, R1, R2> PolyglotReferenceValueLocalizer<T, R1>.map(map: (value: T, localized: TickingValue<R1>, reference: Zoned<Instant>) -> TickingValue<R2>): PolyglotReferenceValueLocalizer<T, R2>

Returns a new PolyglotReferenceValueLocalizer that localizes the received value using this localizer, calls map, and returns whatever TickingValue the mapping function returns.

toTickingValueProvider

fun <T, R> PolyglotReferenceValueLocalizer<T, R>.toTickingValueProvider(value: T): TickingValueProvider<R>

Fixes the value to localize and returns a TickingValueProvider using this PolyglotReferenceValueLocalizer as source for TickingValues.
