<p>Check the static fields of classes conveniently, the usage is <code class="docutils literal notranslate"><span class="pre">getstatic</span> <span class="pre">class_name</span> <span class="pre">field_name</span></code>.</p>

<p>Tip: if the static field is a complex class, you can even use <a class="reference external" href="https://commons.apache.org/proper/commons-ognl/language-guide.html"><code class="docutils literal notranslate"><span class="pre">OGNL</span></code></a> to traverse, filter and access the inner properties of this class.</p>
<div class="toctree-wrapper compound">
<ul>
<li class="toctree-l1"><a class="reference external" href="https://commons.apache.org/proper/commons-ognl/language-guide.html">OGNL official guide</a></li>
<li class="toctree-l1"><a class="reference external" href="https://github.com/alibaba/arthas/issues/71">Special usages</a></li>
</ul>
</div>
<p>E.g. suppose <code class="docutils literal notranslate"><span class="pre">n</span></code> is a <code class="docutils literal notranslate"><span class="pre">Map</span></code> and its key is a <code class="docutils literal notranslate"><span class="pre">Enum</span></code>, then you can achieve this if you want to pick the key with a specific <code class="docutils literal notranslate"><span class="pre">Enum</span></code> value:</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">$ getstatic com.alibaba.arthas.Test n 'entrySet().iterator.{? #this.key.name()=="STOP"}'
field: n
@ArrayList[
@Node[STOP=bbb],
