ProfilerFlowEventType.Next

描述

Use for the flow continuation point.

An example of a flow start point is job scheduling. For instance, IJobExtensions.Schedule generates an implicit Begin Profiler flow event and IJob.Execute generates an implicit Next event.

        using (k_TaskMarker.Auto())

            // Mark the parent k_ScheduleTasksMarker as a beginning of the flow
            ProfilerUnsafeUtility.FlowEvent(flowId, ProfilerFlowEventType.Begin);

            thread.Start();
