java - not to keep references to the objects from this iterator ?
Be careful not to keep references to the objects from this iterator.
To improve GC performance the same object is re-used in next().
请问这段注释是什么含义？

下面的理解对吗？
不要保存迭代器里的对象的引用。
举个例子， iterator里面有十个对象，你用一次next，第一个就被移出了，所有执行完，迭代器为空，如果你在下面还引用这个迭代器里的对象的话，就会报空指针了
