Class YearToSecond

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<YearToSecond>, Interval
    public final class YearToSecond
extends java.lang.Number
implements Interval, java.lang.Comparable<YearToSecond>
    A combined YearToMonth / DayToSecond interval.

    Some databases (e.g. PostgreSQL) allow for mixing YEAR TO MONTH and DAY TO SECOND intervals, despite the many questions such a combination raises. The YearToSecond type intends to model such vendor specific intervals.

    The numeric value of this interval corresponds to its "context free" number of milliseconds. While the DayToSecond interval component can provide such a value easily (being independent of time zones, daylight saving times, leap years, or leap seconds), the YearToMonth component cannot. The implemented rules are those of PostgreSQL:

    • A day has 86400 seconds
    • A month has 30 days
    • A year has 365.25 days
    • A year has 12 months

    Examples:

    • P11M has 330 days
    • P1Y-1M has 330 days
    • P1Y has 365.25 days
    • P1Y1M has 396.25 days

    • Method Detail

      • valueOf

        public static YearToSecond valueOf​(double milli)
        Load a Double representation of a INTERVAL YEAR TO SECOND by assuming standard 24 hour days and 60 second minutes.
        Parameters:
        milli - The number of milliseconds as a fractional number
        Returns:
        The loaded INTERVAL DAY TO SECOND object

      • valueOf

        public static YearToSecond valueOf​(java.time.Duration duration)
        Transform a Duration into a YearToSecond interval by taking its number of milliseconds.

      • toDuration

        public final java.time.Duration toDuration()
        Description copied from interface: Interval
        Get a duration representation of this interval.

        There is an obvious Duration representation for DayToSecond intervals. If the interval contains YearMonth information, then the corresponding duration will use:

        • 1 year = 365.25 days
        • 1 month = 30 days

        This corresponds to PostgreSQL's EXTRACT(EPOCH FROM my_interval) behaviour.

        Specified by:
        toDuration in interface Interval

      • valueOf

        public static YearToSecond valueOf​(java.time.Period period)
        Transform a Period into a YearToSecond interval.

      • valueOf

        public static YearToSecond valueOf​(java.lang.String string)
        Parse a string representation of a INTERVAL YEAR TO SECOND
        Parameters:
        string - A string representation of the form [+|-][years]-[months] [+|-][days] [hours]:[minutes]:[seconds].[fractional seconds]
        Returns:
        The parsed YEAR TO SECOND object, or null if the string could not be parsed.
