AbstractFuture.done介绍

[英]Callback method that is called immediately after the future is completed.

This is called exactly once, after all listeners have executed. By default it does nothing.
[中]在将来完成后立即调用的回调方法。
在所有侦听器执行之后,此函数只调用一次。默认情况下,它什么也不做。

  // We call this after the listeners on the theory that done() will only be used for 'cleanup'
  // oriented tasks (e.g. clearing fields) and so can wait behind listeners which may be executing
  // more important work.  A counter argument would be that done() is trusted code and therefore
  // it would be safe to run before potentially slow or poorly behaved listeners.  Reevaluate this
  // once we have more examples of done() implementations.
