The filter admits two options LevelToMatch and * AcceptOnMatch. If there is an exact match between the value * of the LevelToMatch option and the level of the * {@link LoggerLoggingEvent}, then the {@link decide()} method returns * {@link LoggerFilter::ACCEPT} in case the AcceptOnMatch * option value is set to true, if it is false then * {@link LoggerFilter::DENY} is returned. If there is no match, * {@link LoggerFilter::NEUTRAL} is returned.
