唯一能够为您想要的区间解析的所有功能建模的库实际上是我的库Time4J(范围模块)。例子:
// case 1 (start/end)
System.out.println(MomentInterval.parseISO("2012-01-01T14:15Z/2014-06-20T16:00Z"));
// output: [2012-01-01T14:15:00Z/2014-06-20T16:00:00Z)
// case 1 (with some elements missing at end component and different offset)
System.out.println(MomentInterval.parseISO("2012-01-01T14:15Z/08-11T16:00+00:01"));
// output: [2012-01-01T14:15:00Z/2012-08-11T15:59:00Z)
// case 1 (with missing date and offset at end component)
System.out.println(MomentInterval.parseISO("2012-01-01T14:15Z/16:00"));
// output: [2012-01-01T14:15:00Z/2012-01-01T16:00:00Z)
// case 2 (start/duration)
System.out.println(MomentInterval.parseISO("2012-01-01T14:15Z/P2DT1H45M"));
// output: [2012-01-01T14:15:00Z/2012-01-03T16:00:00Z)
// case 3 (duration/end)
System.out.println(MomentInterval.parseISO("P2DT1H45M/2012-01-01T14:15Z"));
// output: [2011-12-30T12:30:00Z/2012-01-01T14:15:00Z)
// case 4 (duration only, in standard ISO-format)
Duration<IsoUnit> isoDuration = Duration.parsePeriod("P2DT1H45M");
// case 4 (duration only, in alternative representation)
Duration<IsoUnit> isoDuration = Duration.parsePeriod("P0000-01-01T15:00");
System.out.println(isoDuration); // output: P1M1DT15H
一些备注:
其他区间类也存在类似的解析能力,例如在DateInterval
net.time4j.range包中。TimestampInterval
仅用于处理持续时间(也可以跨越日历和时钟单位),另请参见javadoc。还有格式化功能,请参阅嵌套类Duration.Formatter
或本地化版本net.time4j.PrettyTime
(实际上是 86 种语言)。
与 Java-8 ( java.time
-package) 提供互操作性,但不与 Joda-Time 提供互操作性。例如: a 的开始或结束部分MomentInterval
可以很容易地通过getStartAsInstant()
or查询getEndAsInstant()
。
类IsoRecurrence支持重复间隔。例子:
IsoRecurrence<MomentInterval> ir =
IsoRecurrence.parseMomentIntervals("R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M");
ir.intervalStream().forEach(System.out::println);
输出:
[2008-03-01T13:00:00Z/2009-05-11T15:30:00Z)
[2009-05-11T15:30:00Z/2010-07-21T18:00:00Z)
[2010-07-21T18:00:00Z/2011-10-01T20:30:00Z)
[2011-10-01T20:30:00Z/2012-12-11T23:00:00Z)
[2012-12-11T23:00:00Z/2014-02-22T01:30:00Z)
