Interface IThreadPool

All Known Implementing Classes:

ThreadPool

public interface IThreadPool

The ThreadPool manages a pool of threads.
In the thread pool, as its name suggests, some threads are waiting for work to appear in the pool. As soon as there is work one of the waiting threads will take it and work on it.
The pool has an initial amount of threads which are created when the pool is created. It has also a maximum limit to which he can extend the number of threads. When work is added and no thread is currently waiting, the pool creates a new thread unless the maximum count of threads is already reached.
Currently the pool does not destroy any thread he once created.
