"Event equivalent to the (Async)PlayerPreLoginEvent"

Well, I wonder what would be (if any) an event in Sponge API equivalent to AsyncPlayerPreLoginEvent or PlayerPreLoginEvent (from Bukkit).

Pardon if this is a stupid question, but just recently started messing with Sponge API.

Grateful.

Perfect! Thank you very much.
