Worker Archetype

Classes that conform to the worker archetype provide the code to process work items queued on a thread pool.

Implementation

To implement a class conforming to this archetype, the class must provide the following features:

Method

Description

Initialize

Called to initialize the worker object before any requests are passed to Execute.

Execute

Called to process a work item.

Terminate

Called to uninitialize the worker object after all requests have been passed to Execute.

Typedef

Description

RequestType

A typedef for the type of work item that can be processed by the worker class.

A typical worker class looks like this:

class CMyWorker
{
public:
   typedef MyRequestType RequestType;

   BOOL Initialize(void* pvWorkerParam);

   void Execute(MyRequestType request, void* pvWorkerParam, OVERLAPPED* pOverlapped);

   void Terminate(void* pvWorkerParam);
};
