Description

When org.apache.logging.log4j.core.config.LoggerConfig.level is set to null the logging level is inherited from the parent:

public Level getLevel() {
  return level == null ? parent == null ? Level.ERROR : parent.getLevel() : level;
} 

It would be useful to know if level is explicitly set or inherited.

Something like: hasLevel(), isLevelSet(), isLevelInherited(), or something that fits into Log4j terminology.
