org.apache.flink.core.testutils.CheckedThread

所有已实现的接口:

Runnable

public abstract class CheckedThread
extends Thread

A thread that additionally catches exceptions and offers a joining method that re-throws the exceptions.

Rather than overriding Thread.run() (or supplying a Runnable), one needs to extends this class and implement the go() method. That method may throw exceptions.

Exception from the go() method are caught and re-thrown when joining this thread via the sync() method.

方法详细资料

go

public abstract void go()
                 throws Exception

This method needs to be overwritten to contain the main work logic. It takes the role of Thread.run(), but should propagate exceptions.

抛出:

Exception - The exceptions thrown here will be re-thrown in the sync() method.

run

public final void run()

This method is final - thread work should go into the go() method instead.

指定者:

run 在接口中 Runnable

覆盖:

run 在类中 Thread

sync

public void sync()
          throws Exception

Waits until the thread is completed and checks whether any error occurred during the execution.

This method blocks like Thread.join(), but performs an additional check for exceptions thrown from the go() method.

抛出:

Exception

sync

public void sync(long timeout)
          throws Exception

Waits with timeout until the thread is completed and checks whether any error occurred during the execution. In case of timeout an Exception is thrown.

This method blocks like Thread.join(), but performs an additional check for exceptions thrown from the go() method.

抛出:

Exception

trySync

public void trySync(long timeout)
             throws Exception

Waits with timeout until the thread is completed and checks whether any error occurred during the execution.

This method blocks like Thread.join(), but performs an additional check for exceptions thrown from the go() method.

抛出:

Exception
