Deletes all existing profiles, also cancelling all profiling activity. All previously returned pointers to profiles and their contents become invalid after this call.
◆ FindProfile()
Returns a profile by uid.
◆ GetProfile()
Returns a profile by index.

A note on security tokens usage. As scripts from different origins can run inside a single V8 instance, it is possible to have functions from different security contexts intermixed in a single CPU profile. To avoid exposing function names belonging to other contexts, filtering by security token is performed while obtaining profiling results. Returns the number of profiles collected (doesn't include profiles that are being collected at the moment of call.)
◆ StartProfiling()
Starts collecting CPU profile. Title may be an empty string. It is allowed to have several profiles being collected at once. Attempts to start collecting several profiles with the same title are silently ignored. While collecting a profile, functions from all security contexts are included in it. The token-based filtering is only performed when querying for a profile.
◆ StopProfiling()
Stops collecting CPU profile with a given title and returns it. If the title given is empty, finishes the last profile started.
