+

+ <li><a href="../../../../../org/apache/spark/api/java/Optional.html#isPresent--"><code>isPresent()</code></a></li>
+ </ul>
+
+ <p>From <code>com.google.common.base.Optional</code> it implements:</p>
+
+ <ul>
+ <li><a href="../../../../../org/apache/spark/api/java/Optional.html#absent--"><code>absent()</code></a></li>

+
+ <p><code>java.util.Optional</code> itself was not used because at the time, the

+ has in the past caused serious library version conflicts with Guava that can't
