Description
Interface for workers of the thread pool.
A worker is an object that can perform a task. Classes that implement the IThreadPoolWorkItem interface must implement the following two methods:
- ExecuteWork performs the task of the object when called.
- ShouldExecute returns
Trueif the task can be executed, orFalseif the task should not be executed.
The thread pool always checks the value of ShouldExecute before a call to ExecuteWork.
Examples of classes that implement IThreadPoolWorkItem: TWorkerData, TTask (though ITask), TFuture (through IFuture).
