All Implemented Interfaces:
Executor, ThreadPool, DisposableBean, InitializingBean, AsyncListenableTaskExecutor, AsyncTaskExecutor, TaskExecutor, SchedulingTaskExecutor
```
public class SimpleThreadPoolTaskExecutor
extends SimpleThreadPool
implements AsyncListenableTaskExecutor, SchedulingTaskExecutor, InitializingBean, DisposableBean
```
Subclass of Quartz's SimpleThreadPool that implements Spring's TaskExecutor interface and listens to Spring lifecycle callbacks.
Can be shared between a Quartz Scheduler (specified as "taskExecutor") and other TaskExecutor users, or even used completely independent of a Quartz Scheduler (as plain TaskExecutor backend).

2.0

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`afterPropertiesSet()`	Invoked by the containing `BeanFactory` after it has set all bean properties and satisfied `BeanFactoryAware`, `ApplicationContextAware` etc.
`void`	`destroy()`	Invoked by the containing `BeanFactory` on destruction of a bean.
`void`	`execute(Runnable task)`	Execute the given `task`.
`void`	`execute(Runnable task, long startTimeout)`	Execute the given `task`.
`boolean`	`prefersShortLivedTasks()`	This task executor prefers short-lived work units.
`void`	`setWaitForJobsToCompleteOnShutdown(boolean waitForJobsToCompleteOnShutdown)`	Set whether to wait for running jobs to complete on shutdown.
`Future<?>`	`submit(Runnable task)`	Submit a Runnable task for execution, receiving a Future representing that task.
`<T> Future<T>`	`submit(Callable<T> task)`	Submit a Callable task for execution, receiving a Future representing that task.
`ListenableFuture<?>`	`submitListenable(Runnable task)`	Submit a `Runnable` task for execution, receiving a `ListenableFuture` representing that task.

public SimpleThreadPoolTaskExecutor()
```
- Method Detail
  - setWaitForJobsToCompleteOnShutdown
```
public void setWaitForJobsToCompleteOnShutdown(boolean waitForJobsToCompleteOnShutdown)
```
    Set whether to wait for running jobs to complete on shutdown. Default is "false".

    SimpleThreadPool.shutdown(boolean)
  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws SchedulerConfigException
```
    Description copied from interface: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    Specified by:
    afterPropertiesSet in interface InitializingBean
    Throws:
    SchedulerConfigException
  - execute
```
public void execute(Runnable task)
```
    Description copied from interface: TaskExecutor
    Execute the given task.
    The call might return immediately if the implementation uses an asynchronous execution strategy, or might block in the case of synchronous execution.
    Specified by:
    execute in interface Executor
    Specified by:
    execute in interface TaskExecutor
    Parameters:
    task - the Runnable to execute (never null)
  - execute
```
public void execute(Runnable task,
                    long startTimeout)
```
    Description copied from interface: AsyncTaskExecutor
    Execute the given task.
    Specified by:
    execute in interface AsyncTaskExecutor
    Parameters:
    task - the Runnable to execute (never null)
    startTimeout - the time duration (milliseconds) within which the task is supposed to start. This is intended as a hint to the executor, allowing for preferred handling of immediate tasks. Typical values are AsyncTaskExecutor.TIMEOUT_IMMEDIATE or AsyncTaskExecutor.TIMEOUT_INDEFINITE (the default as used by TaskExecutor.execute(Runnable)).
  - submit
```
public Future<?> submit(Runnable task)
```
    Description copied from interface: AsyncTaskExecutor
    Submit a Runnable task for execution, receiving a Future representing that task. The Future will return a null result upon completion.
    Specified by:
    submit in interface AsyncTaskExecutor
    Parameters:
    task - the Runnable to execute (never null)
    Returns:
    a Future representing pending completion of the task
  - submit
```
public <T> Future<T> submit(Callable<T> task)
```
    Description copied from interface: AsyncTaskExecutor
    Submit a Callable task for execution, receiving a Future representing that task. The Future will return the Callable's result upon completion.
    Specified by:
    submit in interface AsyncTaskExecutor
    Parameters:
    task - the Callable to execute (never null)
    Returns:
    a Future representing pending completion of the task
  - submitListenable
```
public ListenableFuture<?> submitListenable(Runnable task)
```
    Description copied from interface: AsyncListenableTaskExecutor
    Submit a Runnable task for execution, receiving a ListenableFuture representing that task. The Future will return a null result upon completion.
    Specified by:
    submitListenable in interface AsyncListenableTaskExecutor
    Parameters:
    task - the Runnable to execute (never null)
    Returns:
    a ListenableFuture representing pending completion of the task
  - submitListenable
```
public <T> ListenableFuture<T> submitListenable(Callable<T> task)
```
    Description copied from interface: AsyncListenableTaskExecutor
    Submit a Callable task for execution, receiving a ListenableFuture representing that task. The Future will return the Callable's result upon completion.
    Specified by:
    submitListenable in interface AsyncListenableTaskExecutor
    Parameters:
    task - the Callable to execute (never null)
    Returns:
    a ListenableFuture representing pending completion of the task
  - prefersShortLivedTasks
```
public boolean prefersShortLivedTasks()
```
    This task executor prefers short-lived work units.
    Specified by:
    prefersShortLivedTasks in interface SchedulingTaskExecutor
    Returns:
    true if this TaskExecutor prefers short-lived tasks
  - destroy
```
public void destroy()
```
    Description copied from interface: DisposableBean
    Invoked by the containing BeanFactory on destruction of a bean.
    Specified by:
    destroy in interface DisposableBean
