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

Range.hasUpperBound介绍

[英]Returns true if this range has an upper endpoint.
[中]如果此范围有上限，则返回true。
