Examples of PooledExecutor

• EDU.oswego.cs.dl.util.concurrent.PooledExecutor
  ialize to use a maximum of 8 threads. static PooledExecutor pool = new PooledExecutor(8); } Here are some sample variants in initialization:

  1. Using a bounded buffer of 10 tasks, at least 4 threads (started only when needed due to incoming requests), but allowing up to 100 threads if the buffer gets full.

      pool = new PooledExecutor(new BoundedBuffer(10), 100); pool.setMinimumPoolSize(4); 

  2. Same as (1), except pre-start 9 threads, allowing them to die if they are not used for five minutes.

      pool = new PooledExecutor(new BoundedBuffer(10), 100); pool.setMinimumPoolSize(4); pool.setKeepAliveTime(1000 * 60 * 5); pool.createThreads(9); 

  3. Same as (2) except clients block if both the buffer is full and all 100 threads are busy:

      pool = new PooledExecutor(new BoundedBuffer(10), 100); pool.setMinimumPoolSize(4); pool.setKeepAliveTime(1000 * 60 * 5); pool.waitWhenBlocked(); pool.createThreads(9); 

  4. An unbounded queue serviced by exactly 5 threads:

      pool = new PooledExecutor(new LinkedQueue()); pool.setKeepAliveTime(-1); // live forever pool.createThreads(5); 

  Usage notes.

  Pools do not mesh well with using thread-specific storage via java.lang.ThreadLocal. ThreadLocal relies on the identity of a thread executing a particular task. Pools use the same thread to perform different tasks.

  If you need a policy not handled by the parameters in this class consider writing a subclass.

  Version note: Previous versions of this class relied on ThreadGroups for aggregate control. This has been removed, and the method interruptAll added, to avoid differences in behavior across JVMs.

  Pooled Executor implementation. Create a thread when we need one, let them die after 5 minutes of inactivity. @author toad
