[logback-dev] [JIRA] Commented: (LBCLASSIC-195) Allow TurboFilters to modify events

Joern Huxhorn commented on LBCLASSIC-195:
-----------------------------------------

Isn't LoggingEvent mostly unmodifiable? What values of the event are supposed to be changed?

I could imagine raising or lowering the Level, for example, but the setter looks like this:
  public void setLevel(Level level) {
    if (this.level != null) {
      throw new IllegalStateException(
          "The level has been already set for this event.");
    }
    this.level = level;
  }

While I see significant use in making LoggingEvent modifiable (I suggested that quite some time ago) it's a quite substantial change, much beyond just changing TurboFilter!
