本文整理了Java中java.util.Collection.removeAll()方法的一些代码示例,展示了Collection.removeAll()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。Collection.removeAll()方法的具体详情如下:
包路径:java.util.Collection
类名称:Collection
方法名:removeAll

Collection.removeAll介绍

[英]Removes all occurrences in this Collection of each object in the specified Collection (optional). After this method returns none of the elements in the passed Collection can be found in this Collectionanymore.
[中]删除指定集合中每个对象在此集合中的所有引用(可选)。此方法返回后,在此Collectionanymore中找不到传递集合中的任何元素。

  // Remove OUT/IN where there is a BOTH
  Collection<RelationshipType> both = tempMap.get( Direction.BOTH );
  tempMap.get( Direction.OUTGOING ).removeAll( both );
  tempMap.get( Direction.INCOMING ).removeAll( both );
  // Convert into a final map
  Map<Direction, RelationshipType[]> map = new EnumMap<>( Direction.class );
  for ( Map.Entry<Direction, Collection<RelationshipType>> entry : tempMap.entrySet() )
