A SplitLogger.T, or split logger, is a general-purpose device for splitting, teeing, or filtering log messages according to their priority levels.

INTERFACE SplitLogger;

IMPORT Logger;

TYPE
  T <: Public;

  Public = Logger.T OBJECT METHODS
    init(child1, child2: Logger.T;
	 levels1 := SET OF Logger.Priority{
	    Logger.Priority.Emerg .. Logger.Priority.Warning};
	 levels2 := SET OF Logger.Priority{
	    Logger.Priority.Notice .. Logger.Priority.Debug}): T;
  END;
Messages at priorities in levels1 are forwarded to child1. Messages at priorities in levels2 are forwarded to child2. Either or both of child1 and child2 may be NIL.

END SplitLogger.
