| /** | |
| * 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> | |
| * | |
| * <p> | |
| * An example for this filter: | |
| * | |
| * {@example ../../examples/php/filter_levelrange.php 19} | |
| * | |
| * <p> | |
| * The corresponding XML file: | |
