Detailed Description

Interface to enable pluggable worker behavior.

One of the WorkerPool threads will invoke Worker::DoWork() when there is work available to do (i.e. when someone calls GetWorkSemaphore()->Post()).

virtual void ion::base::WorkerPool::Worker::DoWork ( )

pure virtual

Called repeatedly in worker thread loop, whenever GetWorkSemaphore() is signaled to indicate that there is work to do.

Note: the WorkerPool implementation occasionally signals the semaphore during state changes (e.g., adding/removing threads, and when suspending or resuming); subclasses of Worker must handle this gracefully. However, there won't be many of these "extra" signals, so DoWork() can simply return as soon as it realizes there is no work to do. In particular, Worker subclasses should not try to proactively limit CPU use, e.g. by sleeping for a few milliseconds when no work is available.

virtual const std::string& ion::base::WorkerPool::Worker::GetName ( ) const

pure virtual

Return the worker's name.
