<div><em>class-patten</em> supports full qualified class name, e.g. com.taobao.test.AAA and com/taobao/test/AAA. It also supports the format of ‘com/taobao/test/AAA’, so that it is convenient to directly copy class name from the exception stack trace without replacing ‘/’ to ‘.’. <br/><br/>
<code class="docutils literal notranslate"><span class="pre">sc</span></code> turns on matching sub-class match by default, that is, <code class="docutils literal notranslate"><span class="pre">sc</span></code> will also search the sub classes of the target class too. If exact-match is desired, pls. use <code class="docutils literal notranslate"><span class="pre">options</span> <span class="pre">disable-sub-class</span> <span class="pre">true</span></code>.</div></blockquote>
