Class AbstractDuration

java.lang.Object

org.goda.time.base.AbstractDuration

All Implemented Interfaces:

Comparable, 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.

Since:

1.0

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.Period(ReadableInstant,ReadableDuration).

Specified by:

toPeriod in interface ReadableDuration

Returns:

a Period created using the millisecond duration from this instance

compareTo

public int compareTo(Object obj)

Compares this duration with the specified duration based on length.

Specified by:

compareTo in interface Comparable

Specified by:

compareTo in interface ReadableDuration

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

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 equal to 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 equal to 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
