The only exposed public methods of the org.slf4j.NDC class are push(String) and pop(). There is a size() method that is private.   I would like to propose the inclusion of a "boolean contains(String)" method that would return whether the currently configured NDC already includes the provided value. I understand with the current approach this would involve iterating over the MDC similar to how size() does since the NDC is actually emulated with MDC keys. ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
