[logback-user] Passing logger level via parameter or determining programmatically?

Hi all, Is there any way to accomplish setting a log level (error, warn, ...) via a parameter, so that I do not have to explicitly code logger.error(...), logger.warn(...)? I would like to be able to code something like logger.log("foo={}", foo); and have it determine the level based on a previously set value. If I could do something like this, then I could change the logging level dynamically in specific classes, rather than changing the level for an entire class as I've seen discussed in the past. Thanks, Larry Smith
