在 Java,finalize在即将收集垃圾时被打上物体(高于此条),这样当它无法收拾。 但是,如果最终确定者再次使目标得以实现,那么情况如何?
直到该物体再次无法收齐为止。
根据http://download-llnw.oracle.com/javase/6/docs/api/java/lang/Object.html#finalize%28%29”rel=“nofollow”>JavaDoc,定稿()将不再被称作。
然后,该物体从基本上收集垃圾。 页: 1 寻找这一术语,而且你应当获得大量有趣的文章。 正如Jim提到的那样,一个重要的一点是,定稿人只能管理一次。
如果你仔细阅读了APIC的描述,你就会看到,定稿人能够再次获得反对。 标语在无法达到之前被弃置,但<条码>定型(<>/条码>赢得的标记不止一次。
因此,你不使用最终确定者。 (Well,许多原因之一)。
已经收集了这方面的资料。 我 look着眼,把它放在一起,但我认为它是一种幻觉。
Yep, PhantomReference:
在收集者确定其参比者可以另外收回后,先验的标语。 甲型六氯环己烷的参考文献通常用于以比 Java定稿机制可能更为灵活的方式安排预先清理行动。
实际上,它还有另一张通行证来检查和确保不再提及该物体。 由于无法在第二张通行证上进行这种测试,你最终不能为物体释放记忆。
由于最后定案仅指任何特定物体的单一时间,而下一个时间是没有参考文件时,它只会释放记忆而不要求最后审定。 http://www.codeguru.com/java/tij/tij0051.shtml“rel=“nofollow”>here。
