| 12 | * \brief This class is a Thread Object which allows to create Functors and attach them to this thread object. |
---|
| 13 | * |
---|
[425] | 14 | * Subclass ThreadWorkerBase to implement your own functor to execute your custom code threaded. |
---|
| 15 | * |
---|
| 16 | * Use setDone(true) to shut down the thread nonblocking, or call cancel() to shut down the thread blocking (both called from outside of the workerthread). |
---|
| 17 | * Inside the workerthread's functor, you can set the functor parameter done=true to shutdown the thread after the current execution. |
