Method Detail

getName

public final String getName()

setWaitForTasksToCompleteOnShutdown

public void setWaitForTasksToCompleteOnShutdown(boolean waitForJobsToCompleteOnShutdown)

Set whether to wait for scheduled tasks to complete on shutdown, not interrupting running tasks and executing all tasks in the queue.

Default is "false", shutting down immediately through interrupting ongoing tasks and clearing the queue. Switch this flag to "true" if you prefer fully completed tasks at the expense of a longer shutdown phase.

Note that Spring's container shutdown continues while ongoing tasks are being completed. If you want this executor to block and wait for the termination of tasks before the rest of the container continues to shut down - e.g. in order to keep up other resources that your tasks may need -, set the "awaitTerminationSeconds" property instead of or in addition to this property.

setAwaitTerminationMillis

public void setAwaitTerminationMillis(long awaitTerminationMillis)

beforeExecute

protected void beforeExecute(Thread t,
                             Runnable r)

todo thread context

Overrides:

execute

public void execute(Runnable command)

Specified by:

execute in interface Executor

Overrides:

Overrides:

terminated in class ThreadPoolExecutor

toString

public final String toString()

appendThreadPoolExecutorDetails

protected void appendThreadPoolExecutorDetails(StringBuilder sb)

Append details about this thread pool to the specified StringBuilder. All details should be appended as key/value pairs in the form "%s = %s, "

Parameters:

sb - the StringBuilder to append to

shutdown

public void shutdown()

Specified by:

shutdown in interface ExecutorService

Overrides:
