Mikael Ståldal commented on LOG4J2-1531: ---------------------------------------- Not arbitrary objects. My proposal is to add this to {{ConfigurationBuilder}}: {code} ConfigurationBuilder<T> add(Appender appender); ConfigurationBuilder<T> add(Filter filter); {code} and this to {{AppenderComponentBuilder}}: {code} AppenderComponentBuilder add(Layout layout); {code} and this to {{FilterableComponentBuilder}}: {code} T add(Filter filter); {code} > Change attribute and component values from String to Object > ----------------------------------------------------------- > > Key: LOG4J2-1531 > URL: https://issues.apache.org/jira/browse/LOG4J2-1531 > Project: Log4j 2 > Issue Type: Improvement > Components: Core > Affects Versions: 2.6.2 > Reporter: Roger Kapsi > Attachments: log4j2-1531-1.0.patch > > > I was looking into creating a ConfigurationFactory/Builder that is backed by > a Clojure DSL.
