Util.toImmutableList介绍

[英]Returns a Collector that accumulates the input elements into a Guava ImmutableList via a ImmutableList.Builder.

It will be obsolete when we move to Bug#upgrade, which has ImmutableList.toImmutableList().
[中]返回一个收集器,该收集器通过ImmutableList将输入元素累积到Guava ImmutableList中。建设者
当我们转向Bug#upgrade时,它将被淘汰,它具有不可变列表。toImmutableList()。
