final class ChronoLocalDateTimeImpl[D <: ChronoLocalDate] extends ChronoLocalDateTime[D] with Temporal with TemporalAdjuster with Serializable

A date-time without a time-zone for the calendar neutral API.

ChronoLocalDateTime is an immutable date-time object that represents a date-time, often viewed as year-month-day-hour-minute-second. This object can also access other fields such as day-of-year, day-of-week and week-of-year.

This class stores all date and time fields, to a precision of nanoseconds. It does not store or represent a time-zone. For example, the value "2nd October 2007 at 13:45.30.123456789" can be stored in an ChronoLocalDateTime.

Specification for implementors

This class is immutable and thread-safe.

    Permalink

    Adjusts the specified temporal object.

    Adjusts the specified temporal object.

    This adjusts the specified temporal object using the logic encapsulated in the implementing class. Examples might be an adjuster that sets the date avoiding weekends, or one that sets the date to the last day of the month.

    There are two equivalent ways of using this method. The first is to invoke this method directly. The second is to use Temporal#with(TemporalAdjuster):

    // these two lines are equivalent, but the second approach is recommended
    temporal = thisAdjuster.adjustInto(temporal);
    temporal = temporal.with(thisAdjuster);
    
    It is recommended to use the second approach, with(TemporalAdjuster), as it is a lot clearer to read in code.

    Specification for implementors

    The implementation must take the input object and adjust it. The implementation defines the logic of the adjustment and is responsible for documenting that logic. It may use any method on Temporal to query the temporal object and perform the adjustment. The returned object must have the same observable type as the input object

    The input object must not be altered. Instead, an adjusted copy of the original must be returned. This provides equivalent, safe behavior for immutable and mutable temporal objects.

    The input temporal object may be in a calendar system other than ISO. Implementations may choose to document compatibility with other calendar systems, or reject non-ISO temporal objects by querying the chronology.

    This method may be called from multiple threads in parallel. It must be thread-safe when invoked.

  10. def atZone(zoneId: ZoneId): ChronoZonedDateTime[D]

    Permalink

    Combines this time with a time-zone to create a ChronoZonedDateTime.

    Combines this time with a time-zone to create a ChronoZonedDateTime.

    This returns a ChronoZonedDateTime formed from this date-time at the specified time-zone. The result will match this date-time as closely as possible. Time-zone rules, such as daylight savings, mean that not every local date-time is valid for the specified zone, thus the local date-time may be adjusted.

    The local date-time is resolved to a single instant on the time-line. This is achieved by finding a valid offset from UTC/Greenwich for the local date-time as defined by the rules of the zone ID.

    In most cases, there is only one valid offset for a local date-time. In the case of an overlap, where clocks are set back, there are two valid offsets. This method uses the earlier offset typically corresponding to "summer".

    In the case of a gap, where clocks jump forward, there is no valid offset. Instead, the local date-time is adjusted to be later by the length of the gap. For a typical one hour daylight savings change, the local date-time will be moved one hour later into the offset typically corresponding to "summer".

    To obtain the later offset during an overlap, call ChronoZonedDateTime#withLaterOffsetAtOverlap() on the result of this method.

    returns

    the zoned date-time formed from this date-time, not null

    Permalink

    Compares this date-time to another date-time, including the chronology.

    Compares this date-time to another date-time, including the chronology.

    The comparison is based first on the underlying time-line date-time, then on the chronology. It is "consistent with equals", as defined by Comparable.

    For example, the following is the comparator order:

    • 2012-12-03T12:00 (ISO)
    • 2012-12-04T12:00 (ISO)
    • 2555-12-04T12:00 (ThaiBuddhist)
    • 2012-12-05T12:00 (ISO)

    Values #2 and #3 represent the same date-time on the time-line. When two values represent the same date-time, the chronology ID is compared to distinguish them. This step is needed to make the ordering "consistent with equals".

    If all the date-time objects being compared are in the same chronology, then the additional chronology stage is not required and only the local date-time is used.

    other

    the other date-time to compare to, not null

    returns

    the comparator value, negative if less, positive if greater

    Returns an object of the same type as this object with the specified period subtracted.

    This method returns a new object based on this one with the specified period subtracted. For example, on a LocalDate, this could be used to subtract a number of years, months or days. The returned object will have the same observable type as this object.

    In some cases, changing a field is not fully defined. For example, if the target object is a date representing the 31st March, then subtracting one month would be unclear. In cases like this, the field is responsible for resolving the result. Typically it will choose the previous valid date, which would be the last valid day of February in this example.

    If the implementation represents a date-time that has boundaries, such as LocalTime, then the permitted units must include the boundary unit, but no multiples of the boundary unit. For example, LocalTime must accept DAYS but not WEEKS or MONTHS.

    Specification for implementors

    Queries this date-time.

    This queries this date-time using the specified query strategy object.

    Queries are a key tool for extracting information from date-times. They exists to externalize the process of querying, permitting different approaches, as per the strategy design pattern. Examples might be a query that checks if the date is the day before February 29th in a leap year, or calculates the number of days to your next birthday.

    The most common query implementations are method references, such as LocalDate::from and ZoneId::from. Further implementations are on TemporalQueries. Queries may also be defined by applications.

    Specification for implementors

    Implementations of this method must behave as follows:

    Gets the range of valid values for the specified field.

    All fields can be expressed as a long integer. This method returns an object that describes the valid range for that value. The value of this temporal object is used to enhance the accuracy of the returned range. If the date-time cannot return the range, because the field is unsupported or for some other reason, an exception will be thrown.

    Note that the result only describes the minimum and maximum valid values and it is important not to read too much into them. For example, there could be values within the range that are invalid for the field.

    Calculates the period between this temporal and another temporal in terms of the specified unit.

    Calculates the period between this temporal and another temporal in terms of the specified unit.

    This calculates the period between two temporals in terms of a single unit. The start and end points are this and the specified temporal. The result will be negative if the end is before the start. For example, the period in hours between two temporal objects can be calculated using startTime.until(endTime, HOURS).

    The calculation returns a whole number, representing the number of complete units between the two temporals. For example, the period in hours between the times 11:30 and 13:29 will only be one hour as it is one minute short of two hours.

    There are two equivalent ways of using this method. The first is to invoke this method directly. The second is to use Temporal):

    // these two lines are equivalent
    between = thisUnit.between(start, end);
    between = start.until(end, thisUnit);
    
    The choice should be made based on which makes the code more readable.

    For example, this method allows the number of days between two dates to be calculated:

    val daysBetween: Long = DAYS.between(start, end);
    // or alternatively

    Implementations must begin by checking to ensure that the input temporal object is of the same observable type as the implementation. They must then perform the calculation for all instances of ChronoUnit. A DateTimeException must be thrown for ChronoUnit instances that are unsupported.

    If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the input temporal as the second argument.

    In summary, implementations must behave in a manner equivalent to this code:

    // check input temporal is the same type as this class
    if (unit instanceof ChronoUnit) {
    // if unit is supported, then calculate and return result
    // else throw DateTimeException for unsupported units
    }
    return unit.between(this, endTemporal);
    

    The target object must not be altered by this method.

    unit

    the unit to measure the period in, not null

    returns

    the amount of the period between this and the end

    Returns an object of the same type as this object with the specified field altered.

    Returns an object of the same type as this object with the specified field altered.

    This returns a new object based on this one with the value for the specified field changed. For example, on a LocalDate, this could be used to set the year, month or day-of-month. The returned object will have the same observable type as this object.

    In some cases, changing a field is not fully defined. For example, if the target object is a date representing the 31st January, then changing the month to February would be unclear. In cases like this, the field is responsible for resolving the result. Typically it will choose the previous valid date, which would be the last valid day of February in this example.

    Specification for implementors

    Implementations must check and handle all fields defined in ChronoField. If the field is supported, then the adjustment must be performed. If unsupported, then a DateTimeException must be thrown.

    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the first argument.

    Implementations must not alter either this object or the specified temporal object. Instead, an adjusted copy of the original must be returned. This provides equivalent, safe behavior for immutable and mutable implementations.

    field

    the field to set in the result, not null

    newValue

    the new value of the field in the result

    returns

    an object of the same type with the specified field set, not null

    Returns an adjusted object of the same type as this object with the adjustment made.

    Returns an adjusted object of the same type as this object with the adjustment made.

    This adjusts this date-time according to the rules of the specified adjuster. A simple adjuster might simply set the one of the fields, such as the year field. A more complex adjuster might set the date to the last day of the month. A selection of common adjustments is provided in TemporalAdjusters. These include finding the "last day of the month" and "next Wednesday". The adjuster is responsible for handling special cases, such as the varying lengths of month and leap years.

    Some example code indicating how and why this method is used:

    date = date.with(Month.JULY);        // most key classes implement TemporalAdjuster
    date = date.with(lastDayOfMonth());  // static import from TemporalAdjusters
    date = date.with(next(WEDNESDAY));   // static import from TemporalAdjusters and DayOfWeek
