         The following is an example of a single checker definition: 
&lt;p&gt;
&lt;pre&gt;
   &lt;extension
         point=&quot;org.eclipse.cdt.codan.ui.checkers&quot;&gt;
      &lt;checker
            class=&quot;org.aaa.AssignmentInConditionChecker&quot;
            id=&quot;org.aaa.AssignmentInConditionChecker&quot;
            name=&quot;Possible Assignment in Condition instead of comparision&quot;&gt;
      &lt;/checker&gt;
   &lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;
The following is an example of a checker that produces two types of errors:
&lt;p&gt;
&lt;pre&gt;
   &lt;extension
         point=&quot;org.eclipse.cdt.codan.ui.checkers&quot;&gt;

      &lt;checker
            class=&quot;org.aaa.NullPointerDereferenceChecker&quot;
            id=&quot;org.aaa.NullPointerDereferenceChecker&quot;
            name=&quot;Null Pointer Dereference checker&quot;&gt;
      &lt;problem id=&quot;org.aaa.npe_must&quot; name=&quot;Null Pointer Dereference&quot;/ defaultSeverity=&quot;Error&quot;&gt;
      &lt;problem id=&quot;org.aaa.npe_may&quot; name=&quot;Possible Null Pointer Dereference&quot;/&gt;
      &lt;/checker&gt;
   &lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;
