Constructor Detail

ScheduledCaughtExecutorService

public ScheduledCaughtExecutorService(int corePoolSize)

Parameters:

corePoolSize - the number of threads to keep in the pool, even if they are idle, unless allowCoreThreadTimeOut is set

See Also:

ScheduledThreadPoolExecutor.ScheduledThreadPoolExecutor(int)

ScheduledCaughtExecutorService

public ScheduledCaughtExecutorService(int corePoolSize,
                                      java.util.concurrent.ThreadFactory threadFactory)

Parameters:

corePoolSize - the number of threads to keep in the pool, even if they are idle, unless allowCoreThreadTimeOut is set

threadFactory - the factory to use when the executor creates a new thread

See Also:

ScheduledThreadPoolExecutor.ScheduledThreadPoolExecutor(int, ThreadFactory)

Method Detail

afterExecute

public void afterExecute(java.lang.Runnable runnable,
                         java.lang.Throwable throwable)

Method invoked upon completion of execution of the given Runnable. This method is invoked by the thread that executed the task. If non-null, the Throwable is the uncaught RuntimeException or Error that caused execution to terminate abruptly. This method will consume a list of java.util.function.BiConsumer with a runnable and a throwable as arguments. See addAfterExecuteConsumer(BiConsumer)

Overrides:

afterExecute in class java.util.concurrent.ThreadPoolExecutor

Parameters:

runnable - the runnable that has completed

throwable - the exception that caused termination, or null if execution completed normally

getAfterExecuteConsumers

public java.util.List<java.util.function.BiConsumer<java.lang.Runnable,java.lang.Throwable>> getAfterExecuteConsumers()

Returns:

the consumers list that will be performed after thread completed normally.

addAfterExecuteConsumer

public void addAfterExecuteConsumer(java.util.function.BiConsumer<java.lang.Runnable,java.lang.Throwable> afterExecuteBiConsumer)

Parameters:

afterExecuteBiConsumer - the consumer that will be performed after thread has completed normally.
