The weak reference from the long-lived object to the short-lived object is kept long after the short-lived object has been destroyed.

Using a weak reference here keeps objects that are above the minimum around as long as possible, but makes them available for GC as required.

在此使用弱引用可以使除最低数量对象以外的对象尽可能久地保持活跃状态，但是使它们可供GC根据需要使用。

If the minimum number of objects is already allocated, then a weak reference to the object is enqueued.

如果已经分配了最低数量的对象，则对象的弱引用被放置到队列中。

GC is a thread of very low priority, so a weak reference object may not be collected immediately.

因为垃圾回收器是一个优先级很低的线程，所以弱引用对象也不一定会马上就会被回收。

From above shall we say that an object can't have a soft reference and a weak reference at the same time?

从以上是否能看出，一个对象不能同时具有软引用和弱引用？

A weak reference is a holder for a reference to an object, called the referent.

弱引用是对一个对象（称为referent）的引用的持有者。
