Class AbstractDuration

  • All Implemented Interfaces:
    Comparable<ReadableDuration>, ReadableDuration
    Direct Known Subclasses:
    BaseDuration
    public abstract class AbstractDuration
extends Object
implements ReadableDuration
    AbstractDuration provides the common behaviour for duration classes.

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

    AbstractDuration subclasses may be mutable and not thread-safe.

    • Method Detail

      • toDuration

        public Duration toDuration()
        Get this duration as an immutable Duration object.
        Specified by:
        toDuration in interface ReadableDuration
        Returns:
        a Duration created using the millisecond duration from this instance

      • toPeriod

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

        Only precise fields in the period type will be used. Thus, only the hour, minute, second and millisecond fields on the period will be used. The year, month, week and day fields will not be populated.

        If the duration is small, less than one day, then this method will perform as you might expect and split the fields evenly. If the duration is larger than one day then all the remaining duration will be stored in the largest available field, hours in this case.

        For example, a duration effectively equal to (365 + 60 + 5) days will be converted to ((365 + 60 + 5) * 24) hours by this constructor.

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

        Specified by:
        toPeriod in interface ReadableDuration
        Returns:
        a Period created using the millisecond duration from this instance

      • isEqual

        public boolean isEqual​(ReadableDuration duration)
        Is the length of this duration equal to the duration passed in.
        Specified by:
        isEqual in interface ReadableDuration
        Parameters:
        duration - another duration to compare to, null means zero milliseconds
        Returns:
        true if this duration is equal to than the duration passed in

      • isLongerThan

        public boolean isLongerThan​(ReadableDuration duration)
        Is the length of this duration longer than the duration passed in.
        Specified by:
        isLongerThan in interface ReadableDuration
        Parameters:
        duration - another duration to compare to, null means zero milliseconds
        Returns:
        true if this duration is longer than the duration passed in

      • isShorterThan

        public boolean isShorterThan​(ReadableDuration duration)
        Is the length of this duration shorter than the duration passed in.
        Specified by:
        isShorterThan in interface ReadableDuration
        Parameters:
        duration - another duration to compare to, null means zero milliseconds
        Returns:
        true if this duration is shorter than the duration passed in

      • equals

        public boolean equals​(Object duration)
        Compares this object with the specified object for equality based on the millisecond length. All ReadableDuration instances are accepted.
        Specified by:
        equals in interface ReadableDuration
        Overrides:
        equals in class Object
        Parameters:
        duration - a readable duration to check against
        Returns:
        true if the length of the duration is equal

      • hashCode

        public int hashCode()
        Gets a hash code for the duration that is compatible with the equals method.
        Specified by:
        hashCode in interface ReadableDuration
        Overrides:
        hashCode in class Object
        Returns:
        a hash code

      • toString

        public String toString()
        Gets the value as a String in the ISO8601 duration format including only seconds and milliseconds.

        For example, "PT72.345S" represents 1 minute, 12 seconds and 345 milliseconds.

        For more control over the output, see PeriodFormatterBuilder.

        Specified by:
        toString in interface ReadableDuration
        Overrides:
        toString in class Object
        Returns:
        the value as an ISO8601 string
