java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractQueue<E>

java.util.concurrent.LinkedBlockingQueue<E>

org.apache.shenyu.common.concurrent.MemoryLimitedLinkedBlockingQueue<E>

所有已实现的接口:

java.io.Serializable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.concurrent.BlockingQueue<E>, java.util.Queue<E>

直接已知子类:

MemoryLimitedTaskQueue

public class MemoryLimitedLinkedBlockingQueue<E>
extends java.util.concurrent.LinkedBlockingQueue<E>

Can completely solve the OOM problem caused by LinkedBlockingQueue.
