包路径：com.google.common.collect.Multiset
类名称：Multiset
方法名：count

Multiset.count介绍

[英]Returns the number of occurrences of an element in this multiset (the count of the element). Note that for an Object#equals-based multiset, this gives the same result as Collections#frequency(which would presumably perform more poorly).

Note: the utility method Iterables#frequency generalizes this operation; it correctly delegates to this method when dealing with a multiset, but it can also accept any other iterable type.
[中]返回此多重集中某个元素的出现次数（元素的计数）。请注意，对于基于对象#equals的多集，这会给出与集合#frequency相同的结果（这可能会执行得更差）。
注：实用方法Iterables#frequency概括了该操作；在处理multiset时，它正确地委托给这个方法，但它也可以接受任何其他iterable类型。
