Class Seconds

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<BaseSingleFieldPeriod>, ReadablePeriod

    public final class Seconds
    extends BaseSingleFieldPeriod
    An immutable time period representing a number of seconds.

    Seconds is an immutable period that can only store seconds. It does not store years, months or hours for example. As such it is a type-safe way of representing a number of seconds in an application.

    The number of seconds is set in the constructor, and may be queried using getSeconds(). Basic mathematical operations are provided - plus(), minus(), multipliedBy() and dividedBy().

    Seconds is thread-safe and immutable.

      • seconds

        public static Seconds seconds​(int seconds)
        Obtains an instance of Seconds that may be cached. Seconds is immutable, so instances can be cached and shared. This factory method provides access to shared instances.
        Parameters:
        seconds - the number of seconds to obtain an instance for
        Returns:
        the instance of Seconds
      • secondsBetween

        public static Seconds secondsBetween​(ReadableInstant start,
                                             ReadableInstant end)
        Creates a Seconds representing the number of whole seconds between the two specified datetimes.
        Parameters:
        start - the start instant, must not be null
        end - the end instant, must not be null
        Returns:
        the period in seconds
        Throws:
        java.lang.IllegalArgumentException - if the instants are null or invalid
      • secondsBetween

                                             ReadablePartial end)
        Creates a Seconds representing the number of whole seconds between the two specified partial datetimes.

        The two partials must contain the same fields, for example you can specify two LocalTime objects.

        Parameters:
        start - the start partial date, must not be null
        end - the end partial date, must not be null
        Returns:
        the period in seconds
        Throws:
        java.lang.IllegalArgumentException - if the partials are null or invalid
      • secondsIn

        public static Seconds secondsIn​(ReadableInterval interval)
        Creates a Seconds representing the number of whole seconds in the specified interval.
        Parameters:
        interval - the interval to extract seconds from, null returns zero
        Returns:
        the period in seconds
        Throws:
        java.lang.IllegalArgumentException - if the partials are null or invalid
      • standardSecondsIn

        public static Seconds standardSecondsIn​(ReadablePeriod period)
        Creates a new Seconds representing the number of complete standard length seconds in the specified period.

        This factory method converts all fields from the period to hours using standardised durations for each field. Only those fields which have a precise duration in the ISO UTC chronology can be converted.

        • One week consists of 7 days.
        • One day consists of 24 hours.
        • One hour consists of 60 minutes.
        • One minute consists of 60 seconds.
        • One second consists of 1000 milliseconds.
        Months and Years are imprecise and periods containing these values cannot be converted.
        Parameters:
        period - the period to get the number of hours from, null returns zero
        Returns:
        the period in seconds
        Throws:
        java.lang.IllegalArgumentException - if the period contains imprecise duration values
      • parseSeconds

        public static Seconds parseSeconds​(java.lang.String periodStr)
        Creates a new Seconds by parsing a string in the ISO8601 format 'PTnS'.

        The parse will accept the full ISO syntax of PnYnMnWnDTnHnMnS however only the seconds component may be non-zero. If any other component is non-zero, an exception will be thrown.

        Parameters:
        periodStr - the period string, null returns zero
        Returns:
        the period in seconds
        Throws:
        java.lang.IllegalArgumentException - if the string format is invalid
      • toStandardWeeks

        public Weeks toStandardWeeks()
        Converts this period in seconds to a period in weeks assuming a 7 day week, 24 hour day, 60 minute hour and 60 second minute.

        This method allows you to convert between different types of period. However to achieve this it makes the assumption that all weeks are 7 days long, all days are 24 hours long, all hours are 60 minutes long and all minutes are 60 seconds long. This is not true when daylight savings time is considered, and may also not be true for some unusual chronologies. However, it is included as it is a useful operation for many applications and business rules.

        Returns:
        a period representing the number of whole weeks for this number of seconds
