) observer.
| Parameters |
observer:ILogObserver | A new-style observer to handle this event. |
eventDict:Dict[str, Any] | An old-style, log event. |
textFromEventDict:Callable[[Dict[str, Any]], Optional[str]] | callable that can format an old-style event as a string. Passed here rather than imported to avoid circular dependency. |
| Note |
It's possible that a new-style event was sent to a LegacyLogObserverWrapper, and may now be getting sent back to a new-style observer. In this case, it's already a new-style event, adapted to also look like an old-style event, and we don't need to tweak it again to be a new-style event, hence this checks for already-defined new-style keys. |
