本文整理了Java中com.google.common.collect.Range.canonical方法的一些代码示例，展示了Range.canonical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.canonical方法的具体详情如下：
包路径：com.google.common.collect.Range
类名称：Range
方法名：canonical

Range.canonical介绍

[英]Returns the canonical form of this range in the given domain. The canonical form has the following properties:

  • equivalence: a.canonical().contains(v) == a.contains(v) for all v (in other words, ContiguousSet.create(a.canonical(domain), domain).equals(
  • uniqueness: unless a.isEmpty(), ContiguousSet.create(a, implies a.canonical(domain).equals(b.canonical(domain))
  • idempotence: a.canonical(domain).canonical(domain).equals(a.canonical(domain))

Furthermore, this method guarantees that the range returned will be one of the following canonical forms:

  • [start..end)
  • [start..+∞)
  • (-∞..end) (only if type C is unbounded below)
  • (-∞..+∞) (only if type C is unbounded below)
    [中]返回给定域中此范围的标准形式。规范形式具有以下属性：
    *等价性：a.规范（）。contains（v）==a.contains（v）代表所有v（换句话说，ContiguousSet.create（a.canonical（domain），domain）。等于(
    *唯一性：除非a.isEmpty（），否则为ContiguousSet。创建（a，意味着a.canonical（域）。等于（b.正则（域））
    *幂等性：典型的（域）。规范（域）。等于（a.规范（域））
    此外，此方法保证返回的范围将是以下规范形式之一：
    *[开始..结束]
    *[开始+∞)
  • (-∞..结束）（仅当类型C在下方无边界时）
  • (-∞..+∞) （仅当类型C在下面是无界的）
