本文整理了Java中com.google.common.collect.Range.span方法的一些代码示例，展示了Range.span的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Range.span方法的具体详情如下：
包路径：com.google.common.collect.Range
类名称：Range
方法名：span

Range.span介绍

[英]Returns the minimal range that #encloses both this range and other. For example, the span of [1..3] and (5..7) is [1..7).

If the input ranges are #isConnected, the returned range can also be called their union. If they are not, note that the span might contain values that are not contained in either input range.

Like #intersection(Range), this operation is commutative, associative and idempotent. Unlike it, it is always well-defined for any two input ranges.
[中]返回#包含此范围和其他范围的最小范围。例如，[1..3]和（5..7）的跨度是[1..7]。
如果输入范围是#未连接的，则返回的范围也可以称为其并集。如果不是，请注意跨度可能包含两个输入范围中都不包含的值。
与#交（值域）一样，这个运算是交换的、结合的和幂等的。与之不同的是，它总是为任意两个输入范围定义良好。
