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

Multiset.size介绍

[英]Returns the total number of all occurrences of all elements in this multiset.

Note: this method does not return the number of distinct elements in the multiset, which is given by entrySet().size().
[中]返回此多重集中所有元素的所有引用总数。
注意：此方法不返回由entrySet（）给出的multiset中不同元素的数量。大小（）。
