Class BaseDuration

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ReadableDuration>, ReadableDuration
    Direct Known Subclasses:
    Duration
    public abstract class BaseDuration
extends AbstractDuration
implements ReadableDuration, java.io.Serializable
    BaseDuration is an abstract implementation of ReadableDuration that stores data in a long duration milliseconds field.

    This class should generally not be used directly by API users. The ReadableDuration interface should be used when different kinds of duration objects are to be referenced.

    BaseDuration subclasses may be mutable and not thread-safe.

    • Method Detail

      • getMillis

        public long getMillis()
        Gets the length of this duration in milliseconds.
        Specified by:
        getMillis in interface ReadableDuration
        Returns:
        the length of the duration in milliseconds.

      • toPeriod

        public Period toPeriod​(PeriodType type)
        Converts this duration to a Period instance using the specified period type and the ISO chronology.

        Only precise fields in the period type will be used. At most these are hours, minutes, seconds and millis - the period type may restrict the selection further.

        For more control over the conversion process, you must pair the duration with an instant, see toPeriodFrom(ReadableInstant, PeriodType).

        Parameters:
        type - the period type to use, null means standard
        Returns:
        a Period created using the millisecond duration from this instance

      • toPeriod

        public Period toPeriod​(Chronology chrono)
        Converts this duration to a Period instance using the standard period type and the specified chronology.

        Only precise fields in the period type will be used. Exactly which fields are precise depends on the chronology. Only the time fields are precise for ISO chronology with a time zone. However, ISO UTC also has precise days and weeks.

        For more control over the conversion process, you must pair the duration with an instant, see toPeriodFrom(ReadableInstant) and toPeriodTo(ReadableInstant)

        Parameters:
        chrono - the chronology to use, null means ISO default
        Returns:
        a Period created using the millisecond duration from this instance

      • toPeriod

        public Period toPeriod​(PeriodType type,
                       Chronology chrono)
        Converts this duration to a Period instance using the specified period type and chronology.

        Only precise fields in the period type will be used. Exactly which fields are precise depends on the chronology. Only the time fields are precise for ISO chronology with a time zone. However, ISO UTC also has precise days and weeks.

        For more control over the conversion process, you must pair the duration with an instant, see toPeriodFrom(ReadableInstant, PeriodType) and toPeriodTo(ReadableInstant, PeriodType)

        Parameters:
        type - the period type to use, null means standard
        chrono - the chronology to use, null means ISO default
        Returns:
        a Period created using the millisecond duration from this instance

      • toPeriodFrom

        public Period toPeriodFrom​(ReadableInstant startInstant)
        Converts this duration to a Period instance by adding the duration to a start instant to obtain an interval using the standard period type.

        This conversion will determine the fields of a period accurately. The results are based on the instant millis, the chronology of the instant, the standard period type and the length of this duration.

        Parameters:
        startInstant - the instant to calculate the period from, null means now
        Returns:
        a Period created using the millisecond duration from this instance

      • toPeriodFrom

        public Period toPeriodFrom​(ReadableInstant startInstant,
                           PeriodType type)
        Converts this duration to a Period instance by adding the duration to a start instant to obtain an interval.

        This conversion will determine the fields of a period accurately. The results are based on the instant millis, the chronology of the instant, the period type and the length of this duration.

        Parameters:
        startInstant - the instant to calculate the period from, null means now
        type - the period type determining how to split the duration into fields, null means All type
        Returns:
        a Period created using the millisecond duration from this instance

      • toPeriodTo

        public Period toPeriodTo​(ReadableInstant endInstant)
        Converts this duration to a Period instance by subtracting the duration from an end instant to obtain an interval using the standard period type.

        This conversion will determine the fields of a period accurately. The results are based on the instant millis, the chronology of the instant, the standard period type and the length of this duration.

        Parameters:
        endInstant - the instant to calculate the period to, null means now
        Returns:
        a Period created using the millisecond duration from this instance

      • toPeriodTo

        public Period toPeriodTo​(ReadableInstant endInstant,
                         PeriodType type)
        Converts this duration to a Period instance by subtracting the duration from an end instant to obtain an interval using the standard period type.

        This conversion will determine the fields of a period accurately. The results are based on the instant millis, the chronology of the instant, the period type and the length of this duration.

        Parameters:
        endInstant - the instant to calculate the period to, null means now
        type - the period type determining how to split the duration into fields, null means All type
        Returns:
        a Period created using the millisecond duration from this instance

      • toIntervalFrom

        public Interval toIntervalFrom​(ReadableInstant startInstant)
        Converts this duration to an Interval starting at the specified instant.
        Parameters:
        startInstant - the instant to start the interval at, null means now
        Returns:
        an Interval starting at the specified instant

      • toIntervalTo

        public Interval toIntervalTo​(ReadableInstant endInstant)
        Converts this duration to an Interval ending at the specified instant.
        Parameters:
        endInstant - the instant to end the interval at, null means now
        Returns:
        an Interval ending at the specified instant
