33/**
34 * This is a very simple filter based on level matching.
35 *
36 * <p>The filter admits two options <b><var>LevelToMatch</var></b> and
37 * <b><var>AcceptOnMatch</var></b>. If there is an exact match between the value
38 * of the <b><var>LevelToMatch</var></b> option and the level of the
39 * {@link LoggerLoggingEvent}, then the {@link decide()} method returns
40 * {@link LOG4PHP_LOGGER_FILTER_ACCEPT} in case the <b><var>AcceptOnMatch</var></b>
41 * option value is set to <i>true</i>, if it is <i>false</i> then
42 * {@link LOG4PHP_LOGGER_FILTER_DENY} is returned. If there is no match,
43 * {@link LOG4PHP_LOGGER_FILTER_NEUTRAL} is returned.</p>
