TemporalQueries.ZoneId Method

Definition

A strict query for the ZoneId.

[Android.Runtime.Register("zoneId", "()Ljava/time/temporal/TemporalQuery;", "", ApiSince=26)]
public static Java.Time.Temporal.ITemporalQuery? ZoneId ();
[<Android.Runtime.Register("zoneId", "()Ljava/time/temporal/TemporalQuery;", "", ApiSince=26)>]
static member ZoneId : unit -> Java.Time.Temporal.ITemporalQuery

Returns

a query that can obtain the zone ID of a temporal, not null

Attributes

Remarks

A strict query for the ZoneId.

This queries a TemporalAccessor for the zone. The zone is only returned if the date-time conceptually contains a ZoneId. It will not be returned if the date-time only conceptually has an ZoneOffset. Thus a java.time.ZonedDateTime will return the result of getZone(), but an java.time.OffsetDateTime will return null.

In most cases, applications should use #zone() as this query is too strict.

The result from JDK classes implementing TemporalAccessor is as follows:<br> LocalDate returns null<br> LocalTime returns null<br> LocalDateTime returns null<br> ZonedDateTime returns the associated zone<br> OffsetTime returns null<br> OffsetDateTime returns null<br> ChronoLocalDate returns null<br> ChronoLocalDateTime returns null<br> ChronoZonedDateTime returns the associated zone<br> Era returns null<br> DayOfWeek returns null<br> Month returns null<br> Year returns null<br> YearMonth returns null<br> MonthDay returns null<br> ZoneOffset returns null<br> Instant returns null<br>
