类 MemorySafeLinkedBlockingQueue<E>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractQueue<E>

java.util.concurrent.LinkedBlockingQueue<E>

org.apache.dubbo.common.threadpool.MemorySafeLinkedBlockingQueue<E>

所有已实现的接口:

Serializable, Iterable<E>, Collection<E>, BlockingQueue<E>, Queue<E>

public class MemorySafeLinkedBlockingQueue<E>
extends LinkedBlockingQueue<E>

Can completely solve the OOM problem caused by LinkedBlockingQueue, does not depend on Instrumentation and is easier to use than MemoryLimitedLinkedBlockingQueue.
