I think I have pointed you to my implementation of a custom operator doing set operations.<br>What keeps you from adopting this technique?<br>-W<br><br><br><div class="gmail_quote">2010/10/11 Kumar Pandey <span dir="ltr">&lt;<a href="mailto:kumar.pandey@gmail.com">kumar.pandey@gmail.com</a>&gt;</span><br>

<br></div><div>Here is the problem space.</div><div><br></div><div>I have a rule that can have a superset of elements such as say &quot;String1&quot;, &quot;String2&quot;, &quot;String3&quot; , &quot;String4&quot;. These are known in rule creation time.</div>

<div><br></div><div>Fact can have subset say &quot;String1&quot;, &quot;String4&quot;</div><div><br></div><div>How can I form a drl to check to verify that fact is a subset of elements in the rule?</div><div><br></div><div>

I need to not fire the rule if fact is a subset but I should  be able to add a not if I can first figure out if it is a sub set.</div><div><br></div><div>Any help would be greatly appreciated.</div><div><br></div><div>Thanks</div>
