类 TaskThreadPoolExecutor

java.lang.Object

java.util.concurrent.AbstractExecutorService

java.util.concurrent.ThreadPoolExecutor

com.qq.tars.common.util.concurrent.TaskThreadPoolExecutor

所有已实现的接口:

Executor, ExecutorService

public class TaskThreadPoolExecutor
extends ThreadPoolExecutor

Same as a java.util.concurrent.ThreadPoolExecutor but implements a much more efficient getSubmittedCount() method, to be used to properly handle the work queue. If a RejectedExecutionHandler is not specified a default one will be configured and that one will always throw a RejectedExecutionException

方法详细资料

getThreadRenewalDelay

public long getThreadRenewalDelay()

setThreadRenewalDelay

public void setThreadRenewalDelay(long threadRenewalDelay)

afterExecute

protected void afterExecute(Runnable r,
                            Throwable t)

覆盖:

afterExecute 在类中 ThreadPoolExecutor

stopCurrentThreadIfNeeded

protected void stopCurrentThreadIfNeeded()

If the current thread was started before the last time when a context was stopped, an exception is thrown so that the current thread is stopped.

currentThreadShouldBeStopped

protected boolean currentThreadShouldBeStopped()

getSubmittedCount

public int getSubmittedCount()

execute

public void execute(Runnable command)

指定者:

execute 在接口中 Executor

覆盖:

execute 在类中 ThreadPoolExecutor

execute

public void execute(Runnable command,
                    long timeout,
                    TimeUnit unit)

Executes the given command at some time in the future. The command may execute in a new thread, in a pooled thread, or in the calling thread, at the discretion of the Executor implementation. If no threads are available, it will be added to the work queue. If the work queue is full, the system will wait for the specified time and it throw a RejectedExecutionException if the queue is still full after that.

参数:

command - the runnable task

抛出:

RejectedExecutionException - if this task cannot be accepted for execution - the queue is full

NullPointerException - if command or unit is null

contextStopping

public void contextStopping()
