注解

尽管ImmutableHashSet<T>.Union和其他方法已为集合提供快速的批量更改操作ImmutableHashSet<T>.Builder , 但该类允许对具有相同效率的集进行多个更改组合。Although ImmutableHashSet<T>.Union and other methods already provide fast bulk change operations on a collection, the ImmutableHashSet<T>.Builder class allows multiple combinations of changes to be made to a set with equal efficiency.
