Remarks
A query for the Chronology.
This queries a TemporalAccessor for the chronology. If the target TemporalAccessor represents a date, or part of a date, then it should return the chronology that the date is expressed in. As a result of this definition, objects only representing time, such as LocalTime, will return null.
The result from JDK classes implementing TemporalAccessor is as follows:<br> LocalDate returns IsoChronology.INSTANCE<br> LocalTime returns null (does not represent a date)<br> LocalDateTime returns IsoChronology.INSTANCE<br> ZonedDateTime returns IsoChronology.INSTANCE<br> OffsetTime returns null (does not represent a date)<br> OffsetDateTime returns IsoChronology.INSTANCE<br> ChronoLocalDate returns the associated chronology<br> ChronoLocalDateTime returns the associated chronology<br> ChronoZonedDateTime returns the associated chronology<br> Era returns the associated chronology<br> DayOfWeek returns null (shared across chronologies)<br> Month returns IsoChronology.INSTANCE<br> Year returns IsoChronology.INSTANCE<br> YearMonth returns IsoChronology.INSTANCE<br> MonthDay returns null IsoChronology.INSTANCE<br> ZoneOffset returns null (does not represent a date)<br> Instant returns null (does not represent a date)<br>
The method java.time.chrono.Chronology#from(TemporalAccessor) can be used as a TemporalQuery via a method reference, Chronology::from. That method is equivalent to this query, except that it throws an exception if a chronology cannot be obtained.
