组合两个Joda-Time Interval对象 [英] Make a union of two Joda-Time Interval objects

问题描述

在 Joda-Time 中，有没有办法创建一个 Interval 作为另外两个间隔的联合。我知道交叉路口方法称为 重叠 （和重叠）。但是我看不到任何联合方法。

In Joda-Time, is there any way to create a Interval as a union of two other intervals. I know there is intersection method which is called overlap (and overlaps). But I can not see any union methods.

推荐答案

如果你想要一个覆盖其他的间隔，只需创建一个新的间隔从 min（a.start，b.start）运行到 max（a.end，b.end）。

If you want an interval that "covers" two others, just create a new interval that runs from min(a.start, b.start) to max(a.end, b.end).

如果您还需要表示差距，那么您需要编写自己的类来处理所需的行为。没有什么内置于Joda-time，因为有几种可能的解释，它对联合不连续的间隔意味着什么。

If you need to represent the gap as well, then you'll need to write your own classes to handle the behavior you want. There's nothing builtin to Joda-time for this as there are several possible interpretations of what it means to "union" non-contiguous intervals.
