<p>To be of any use, a <code><a class="el" href="classlog4cxx_1_1rolling_1_1_rolling_file_appender.html" title="RollingFileAppender extends log4cxx::FileAppender to backup the log files depending on RollingPolicy ...">RollingFileAppender</a></code> instance must have both a <code><a class="el" href="classlog4cxx_1_1rolling_1_1_rolling_policy.html" title="A RollingPolicy is responsible for performing the rolling over of the active log file.">RollingPolicy</a></code> and a <code><a class="el" href="classlog4cxx_1_1rolling_1_1_triggering_policy.html" title="A TriggeringPolicy controls the conditions under which rollover occurs.">TriggeringPolicy</a></code> set up. However, if its <code><a class="el" href="classlog4cxx_1_1rolling_1_1_rolling_policy.html" title="A RollingPolicy is responsible for performing the rolling over of the active log file.">RollingPolicy</a></code> also implements the <code><a class="el" href="classlog4cxx_1_1rolling_1_1_triggering_policy.html" title="A TriggeringPolicy controls the conditions under which rollover occurs.">TriggeringPolicy</a></code> interface, then only the former needs to be set up. For example, <a class="el" href="classlog4cxx_1_1rolling_1_1_time_based_rolling_policy.html">TimeBasedRollingPolicy</a> acts both as a <code><a class="el" href="classlog4cxx_1_1rolling_1_1_rolling_policy.html" title="A RollingPolicy is responsible for performing the rolling over of the active log file.">RollingPolicy</a></code> and a <code><a class="el" href="classlog4cxx_1_1rolling_1_1_triggering_policy.html" title="A TriggeringPolicy controls the conditions under which rollover occurs.">TriggeringPolicy</a></code>.</p>
