◆ ExecuteSlice()

void CMMFlusher::ExecuteSlice ( TSrvThreadNum  thr_num)
privatevirtual

This is the main method to do all work this task should do.

This method will be called periodically while somebody calls SetRunnable() or RunAfter() on this task. But number of calls to this method won't match number of calls to SetRunnable() – if several calls to SetRunnable() are made before ExecuteSlice() had a chance to execute it will be called only once. Task's code inside ExecuteSlice() should understand itself how much work it needs to do and call SetRunnable() again if needed (or do all the work before returning from ExecuteSlice()). Parameter thr_num is number of thread on which ExecuteSlice() is called.

Implements CSrvTask.
