[Null Objects, Monitoring]
Detailed Description
An object that implements IMonitorThreadPool and does nothing.Public Member Functions | |
| void | OnThreadPoolThreadCreated () override |
| Called when a thread is created. Note that this is NOT called from the thread itself. | |
| void | OnThreadPoolThreadStarted () override |
| Called when a thread is started. Note that this IS called from the thread itself. | |
| void | OnThreadPoolDispatch () override |
| Called when a work item is dispatched to the thread pool. Note that this is NOT called when I/O completions are dispatched to the pool as there's no way to know when this happens. However this IS called when you manually dispatch work items to the pool and so the difference between an events/sec counter incremented by this function and a similar counter that is incremented when processing starts will show the I/O completions. | |
| void | OnThreadPoolWorkItemsDequeued (const DWORD) override |
| Called when work items are dequeued by a thread. This includes items that are manually dispatched and I/O completions. Some pools may be able to dequeue multiple work items at once, whilst others can only dequeue a single work item at a time. | |
| void | OnThreadPoolProcessingStarted (const bool) override |
| Called when a thread in the pool starts working on a work item that has been dispatched to the pool. Some pools can be configured to issue a callback on this method when the queue reports as empty. If they do this then dataAvailable will be false. | |
| void | OnThreadPoolProcessingStopped (const bool) override |
| Called when a thread in the pool finishes working on a work item that has been dispatched to the pool. If the pool can report queue empty then this will be called with dataAvailable as false. | |
| void | OnThreadPoolThreadStopped () override |
| Called when a thread is destroyed. Note that this IS called from the thread itself. | |
| void | OnThreadPoolThreadDestroyed () override |
| Called when a thread is destroyed. Note that this is NOT called from the thread itself. | |
| void | OnThreadPoolError (const _tstring &) override |
| Called if there's an unexpected error on a thread in the pool, generally this means that there was an exception thrown whilst dealing with a work item. The thread will continue and pretty much all you can do is log or ignore the message... | |
