ProfilingAware (Apache TinkerPop 3.8.0-SNAPSHOT API)

```
public interface ProfilingAware
```
Marks a Step as one that is aware of profiling. A good example of where this is important is with GroupStep which needs to track and hold a Barrier, which is important for the ProfileStrategy to know about. Once the ProfileStep is injected the Barrier needs to be recalculated so that the timer can be properly started on the associated ProfileStep. Without that indirect start of the timer, the operation related to the Barrier will not be properly accounted for and when metrics are normalized it is possible to end up with a negative timing.

Nested Class Summary

`static class`	`ProfilingAware.ProfiledBarrier`	A helper class which holds a `Barrier` and it's related `ProfileStep` so that the latter can have its timer started and stopped appropriately.

Method Summary

All Methods Instance Methods Default Methods Deprecated Methods
Modifier and Type	Method	Description
`default void`	`prepareForProfiling()`	Deprecated. As of release 3.8.0, not directly replaced because a simple call to `Step.reset()` at traversal lock can more generally do what is needed by this much more specific API.
