public class MemoryLimitedTaskQueue<R extends java.lang.Runnable>

MemoryLimitedTaskQueue in the ShenyuThreadPoolExecutor. It offer a task if the executor's submittedTaskCount less than currentPoolThreadSize or the currentPoolThreadSize more than executor's maximumPoolSize. That can make the executor create new worker when the task num is bigger than corePoolSize but less than maximumPoolSize.

方法详细资料

setExecutor

public void setExecutor(ShenyuThreadPoolExecutor executor)

set the executor.

参数:

executor - executor

offer

public boolean offer(java.lang.Runnable runnable)

指定者:

offer 在接口中 java.util.concurrent.BlockingQueue<java.lang.Runnable>

指定者:

offer 在接口中 java.util.Queue<java.lang.Runnable>

覆盖:

offer 在类中 MemoryLimitedLinkedBlockingQueue<java.lang.Runnable>

retryOffer

public boolean retryOffer(java.lang.Runnable o,
                          long timeout,
                          java.util.concurrent.TimeUnit unit)
                   throws java.lang.InterruptedException

retry offer task.

参数:

o - task

timeout - timeout

unit - timeout unit

返回:

offer success or not

抛出:

java.util.concurrent.RejectedExecutionException - if executor is terminated.

java.lang.InterruptedException - if the current thread is interrupted.
