Class Interval
- ReadableInterval, Serializable
public final class Interval
Interval is the standard implementation of an immutable time interval.
A time interval represents a period of time between two instants.
Intervals are inclusive of the start instant and exclusive of the end.
The end instant is always greater than or equal to the start instant.
Intervals have a fixed millisecond duration.
This is the difference between the start and end instants.
The duration is represented separately by
ReadableDuration
.
As a result, intervals are not comparable.
To compare the length of two intervals, you should compare their durations.
An interval can also be converted to a
ReadablePeriod
.
This represents the difference between the start and end points in terms of fields
such as years and days.
Interval is thread-safe and immutable.

Constructs an interval from a start instant and a time period.

if present, otherwise the chronology of the period is used.

- the period of this interval, null means zero length

public Interval(ReadablePeriod period,
ReadableInstant end)
Constructs an interval from a time period and an end instant.
When forming the interval, the chronology from the instant is used
if present, otherwise the chronology of the period is used.
period
- the period of this interval, null means zero lengthend
- end of this interval, null means now
abuts
public boolean abuts(ReadableInterval interval)
Does this interval abut with the interval specified.
Intervals are inclusive of the start instant and exclusive of the end.
An interval abuts if it starts immediately after, or ends immediately
before this interval without overlap.
A zero duration interval abuts with itself.
When two intervals are compared the result is one of three states:
(a) they abut, (b) there is a gap between them, (c) they overlap.
The abuts state takes precedence over the other two, thus a zero duration
interval at the start of a larger interval abuts and does not overlap.
For example:
[09:00 to 10:00) abuts [08:00 to 08:30) = false (completely before)
[09:00 to 10:00) abuts [08:00 to 09:00) = true
[09:00 to 10:00) abuts [08:00 to 09:01) = false (overlaps)
[09:00 to 10:00) abuts [09:00 to 09:00) = true
[09:00 to 10:00) abuts [09:00 to 09:01) = false (overlaps)
[09:00 to 10:00) abuts [10:00 to 10:00) = true
[09:00 to 10:00) abuts [10:00 to 10:30) = true
[09:00 to 10:00) abuts [10:30 to 11:00) = false (completely after)
[14:00 to 14:00) abuts [14:00 to 14:00) = true
[14:00 to 14:00) abuts [14:00 to 15:00) = true
[14:00 to 14:00) abuts [13:00 to 14:00) = true
interval
- the interval to examine, null means now
- true if the interval abuts
gap
public Interval gap(ReadableInterval interval)
Gets the gap between this interval and another interval.
The other interval can be either before or after this interval.
Intervals are inclusive of the start instant and exclusive of the end.
An interval has a gap to another interval if there is a non-zero
duration between them. This method returns the amount of the gap only
if the intervals do actually have a gap between them.
If the intervals overlap or abut, then null is returned.
When two intervals are compared the result is one of three states:
(a) they abut, (b) there is a gap between them, (c) they overlap.
The abuts state takes precedence over the other two, thus a zero duration
interval at the start of a larger interval abuts and does not overlap.
The chronology of the returned interval is the same as that of
this interval (the chronology of the interval parameter is not used).
Note that the use of the chronology was only correctly implemented
in version 1.3.
interval
- the interval to examine, null means now
- the gap interval, null if no gap
overlap
public Interval overlap(ReadableInterval interval)
Gets the overlap between this interval and another interval.
Intervals are inclusive of the start instant and exclusive of the end.
An interval overlaps another if it shares some common part of the
datetime continuum. This method returns the amount of the overlap,
only if the intervals actually do overlap.
If the intervals do not overlap, then null is returned.
When two intervals are compared the result is one of three states:
(a) they abut, (b) there is a gap between them, (c) they overlap.
The abuts state takes precedence over the other two, thus a zero duration
interval at the start of a larger interval abuts and does not overlap.
The chronology of the returned interval is the same as that of
this interval (the chronology of the interval parameter is not used).
Note that the use of the chronology was only correctly implemented
in version 1.3.
