SimpleAsyncTaskExecutor (bboss-core 6.2.2 API)

- org.frameworkset.util.CustomizableThreadCreator
- - org.frameworkset.schedule.SimpleAsyncTaskExecutor

所有已实现的接口:

java.io.Serializable, java.util.concurrent.Executor, AsyncListenableTaskExecutor, AsyncTaskExecutor, TaskExecutor
```
public class SimpleAsyncTaskExecutor
extends org.frameworkset.util.CustomizableThreadCreator
implements AsyncListenableTaskExecutor, java.io.Serializable
```
TaskExecutor implementation that fires up a new Thread for each task, executing it asynchronously.
Supports limiting concurrent threads through the "concurrencyLimit" bean property. By default, the number of concurrent threads is unlimited.
NOTE: This implementation does not reuse threads! Consider a thread-pooling TaskExecutor implementation instead, in particular for executing a large number of short-lived tasks.

从以下版本开始:

```
public SimpleAsyncTaskExecutor()
```
    Create a new SimpleAsyncTaskExecutor with default thread name prefix.
  - SimpleAsyncTaskExecutor
```
public SimpleAsyncTaskExecutor(java.lang.String threadNamePrefix)
```
    Create a new SimpleAsyncTaskExecutor with the given thread name prefix.
    
    参数:
    
    threadNamePrefix - the prefix to use for the names of newly created threads
  - SimpleAsyncTaskExecutor
```
public SimpleAsyncTaskExecutor(java.util.concurrent.ThreadFactory threadFactory)

    Create a new SimpleAsyncTaskExecutor with the given external thread factory.

```
public void setThreadFactory(java.util.concurrent.ThreadFactory threadFactory)
```
    Specify an external factory to use for creating new Threads, instead of relying on the local properties of this executor.
    You may specify an inner ThreadFactory bean or also a ThreadFactory reference obtained from JNDI (on a Java EE 6 server) or some other lookup mechanism.

  - getThreadFactory
```
public final java.util.concurrent.ThreadFactory getThreadFactory()
```
    Return the external factory to use for creating new Threads, if any.
  - setConcurrencyLimit
```
public void setConcurrencyLimit(int concurrencyLimit)
```
    Set the maximum number of parallel accesses allowed. -1 indicates no concurrency limit at all.
    In principle, this limit can be changed at runtime, although it is generally designed as a config time setting. NOTE: Do not switch between -1 and any concrete limit at runtime, as this will lead to inconsistent concurrency counts: A limit of -1 effectively turns off concurrency counting completely.

  - getConcurrencyLimit
```
public final int getConcurrencyLimit()
```
    Return the maximum number of parallel accesses allowed.
  - isThrottleActive
```
public final boolean isThrottleActive()
```
    Return whether this throttle is currently active.
    
    返回:
    
    true if the concurrency limit for this instance is active

    execute 在接口中 java.util.concurrent.Executor
    
    指定者:

    task - the Runnable to execute (never null)

```
public void execute(java.lang.Runnable task,
                    long startTimeout)
```
    Executes the given task, within a concurrency throttle if configured (through the superclass's settings).
    Executes urgent tasks (with 'immediate' timeout) directly, bypassing the concurrency throttle (if active). All other tasks are subject to throttling.
    
    指定者:
    
    execute 在接口中 AsyncTaskExecutor
    
    参数:
    
    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)).
