−/**
+
− * This is a very simple filter based on level matching, which can be
+
− * used to reject messages with priorities outside a certain range.
+
− *
+
− * <p>The filter admits three options <b><var>LevelMin</var></b>, <b><var>LevelMax</var></b>
+
− * and <b><var>AcceptOnMatch</var></b>.</p>
+
− *
+
− * <p>If the level of the {@link LoggerLoggingEvent} is not between Min and Max
+
− * (inclusive), then {@link LoggerFilter::DENY} is returned.</p>
+
− *
+
− * <p>If the Logging event level is within the specified range, then if
+
− * <b><var>AcceptOnMatch</var></b> is <i>true</i>,
+
− * {@link LoggerFilter::ACCEPT} is returned, and if
+
− * <b><var>AcceptOnMatch</var></b> is <i>false</i>,
+
− * {@link LoggerFilter::NEUTRAL} is returned.</p>
+
− *
+
− * <p>If <b><var>LevelMin</var></b> is not defined, then there is no
+
− * minimum acceptable level (i.e. a level is never rejected for
+
− * being too "low"/unimportant).  If <b><var>LevelMax</var></b> is not
+
− * defined, then there is no maximum acceptable level (ie a
+
− * level is never rejected for being too "high"/important).</p>
+
− *
+
− * <p>Refer to the {@link LoggerAppender::setThreshold()} method
+
− * available to <b>all</b> appenders extending {@link LoggerAppender}
+
− * for a more convenient way to filter out events by level.</p>
+
