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

Multimap.values介绍

[英]Returns a view collection containing the value from each key-value pair contained in this multimap, without collapsing duplicates (so values().size() == size()).

Changes to the returned collection will update the underlying multimap, and vice versa. However, adding to the returned collection is not possible.
[中]返回一个视图集合，其中包含此多重映射中包含的每个键值对的值，而不折叠重复项（so values（）。size（）==size（）。
对返回集合的更改将更新基础多重映射，反之亦然。但是，无法添加到返回的集合中。
