LinkedBlockingQueue的insert和remove方法线程安全吗? [英] Are LinkedBlockingQueue's insert and remove methods thread safe?
问题描述
我在两个不同的线程之间使用 LinkedBlockingQueue
。一个线程通过添加
添加数据,而另一个线程通过接收
接收数据。
I'm using LinkedBlockingQueue
between two different threads. One thread adds data via add
, while the other thread receives data via take
.
我的问题是,我需要同步访问添加
和采取
。 LinkedBlockingQueue
的插入和删除方法线程安全吗?
My question is, do I need to synchronize access to add
and take
. Is LinkedBlockingQueue
's insert and remove methods thread safe?
推荐答案
是。从文档:
BlockingQueue实现是
线程安全的所有排队方法
使用
内部锁然而,批量
收集操作addAll,
containsAll,retainAll和removeAll
不一定执行
atomically除非另有规定$ b所以它是
可能,例如,对于addAll(c)
失败(抛出异常)之后
只添加
中的一些元素c。
"BlockingQueue implementations are thread-safe. All queuing methods achieve their effects atomically using internal locks or other forms of concurrency control. However, the bulk Collection operations addAll, containsAll, retainAll and removeAll are not necessarily performed atomically unless specified otherwise in an implementation. So it is possible, for example, for addAll(c) to fail (throwing an exception) after adding only some of the elements in c."
