本文整理了Java中org.apache.commons.collections.Bag.contains()方法的一些代码示例，展示了Bag.contains()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。Bag.contains()方法的具体详情如下：
包路径：org.apache.commons.collections.Bag
类名称：Bag
方法名：contains

Bag.contains介绍

英 Returns true if the bag contains all elements in the given collection, respecting cardinality. That is, if the given collection coll contains n copies of a given object, calling #getCount(Object) on that object must be >= n for all n in coll.

The Collection#containsAll(Collection) method specifies that cardinality should not be respected; this method should return true if the bag contains at least one of every object contained in the given collection.
[中]（违例）如果包包含给定集合中的所有元素，则返回true，并考虑基数。也就是说，如果给定集合coll包含给定对象的n个副本，则对coll中的所有n调用该对象上的#getCount（对象）必须为>= n。
Collection#containsAll（Collection）方法指定不应尊重基数；如果包包含给定集合中包含的每个对象中至少一个，则此方法应返回true。
