public interface

ReadableDuration

implements Comparable<T>
org.joda.time.ReadableDuration
Known Indirect Subclasses

Class Overview

Defines an exact duration of time in milliseconds.

The implementation of this interface may be mutable or immutable. This interface only gives access to retrieve data, never to change it.

Methods that are passed a duration as a parameter will treat null as a zero length duration.

Summary

Public Methods
abstract int compareTo(Object obj)
Compares this duration with the specified duration based on length.
abstract boolean equals(Object readableDuration)
Compares this object with the specified object for equality based on the millisecond length.
abstract long getMillis()
Gets the total length of this duration in milliseconds.
abstract int hashCode()
Gets a hash code for the duration that is compatable with the equals method.
abstract boolean isEqual(ReadableDuration duration)
Is the length of this duration equal to the duration passed in.
abstract boolean isLongerThan(ReadableDuration duration)
Is the length of this duration longer than the duration passed in.
abstract boolean isShorterThan(ReadableDuration duration)
Is the length of this duration shorter than the duration passed in.
abstract Duration toDuration()
Get this duration as an immutable Duration object.
abstract Period toPeriod()
Converts this duration to a Period instance using the standard period type and the ISO chronology.
abstract String toString()
Gets the value as a String in the ISO8601 duration format using hours, minutes and seconds (including fractional milliseconds).

Public Methods

public abstract int compareTo (Object obj)

Compares this duration with the specified duration based on length.

Parameters
obj a duration to check against
Returns
  • negative value if this is less, 0 if equal, or positive value if greater
Throws
NullPointerException if the object is null
ClassCastException if the given object is not supported

public abstract boolean equals (Object readableDuration)

Compares this object with the specified object for equality based on the millisecond length. All ReadableDuration instances are accepted.

Parameters
readableDuration a readable duration to check against
Returns
  • true if the length of the duration is equal

public abstract long getMillis ()

Gets the total length of this duration in milliseconds.

Returns
  • the total length of the time duration in milliseconds.

public abstract int hashCode ()

Gets a hash code for the duration that is compatable with the equals method. The following formula must be used:

  long len = getMillis();
  return (int) (len ^ (len >>> 32));
 

Returns
  • a hash code

public abstract boolean isEqual (ReadableDuration duration)

Is the length of this duration equal to the duration passed in.

Parameters
duration another duration to compare to, null means zero milliseconds
Returns
  • true if this duration is equal to than the duration passed in

public abstract boolean isLongerThan (ReadableDuration duration)

Is the length of this duration longer than the duration passed in.

Parameters
duration another duration to compare to, null means zero milliseconds
Returns
  • true if this duration is equal to than the duration passed in

public abstract boolean isShorterThan (ReadableDuration duration)

Is the length of this duration shorter than the duration passed in.

Parameters
duration another duration to compare to, null means zero milliseconds
Returns
  • true if this duration is equal to than the duration passed in

public abstract Duration toDuration ()

Get this duration as an immutable Duration object.

This will either typecast this instance, or create a new Duration.

Returns
  • a Duration created using the millisecond duration from this instance

public abstract 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).

Returns
  • a Period created using the millisecond duration from this instance

public abstract String toString ()

Gets the value as a String in the ISO8601 duration format using hours, minutes and seconds (including fractional milliseconds).

For example, "PT6H3M7S" represents 6 hours, 3 minutes, 7 seconds.

Returns
  • the value as an ISO8601 string
