title: Defining required hash values in a javadoc
body: <p>Let's say I have a Java method like this:</p>
  
  <pre><code>void configure(Map&lt;String, String&gt; values) {
      assert values.containsKey("x"), "Missing parameter x"
  }
  </code></pre>
  
  <p>Is it possible to specify in the JavaDoc comment that "x" is a required value in <code>values</code>?</p>
