Class TaskQueue
- All Implemented Interfaces:
Serializable,Iterable<Runnable>,Collection<Runnable>,BlockingQueue<Runnable>,Queue<Runnable>,RetryableQueue<Runnable>
As task queue specifically designed to run with a thread pool executor. The
task queue is optimised to properly utilize threads within a thread pool
executor. If you use a normal queue, the executor will spawn threads when
there are idle threads and you won't be able to force items onto the queue
itself.
