 			Lombok does not (currently) have any runtime dependencies which means lombok does not (currently) ship with any useful extension methods so you'll have to make your own. However, here's one that might spark your imagination: <br />
 			<pre>public class ObjectExtensions {
-	public static &lt;T&gt; or(T object, T ifNull) {
+	public static &lt;T&gt; T or(T object, T ifNull) {
 		return object != null ? object : ifNull;
 	}
 }</pre><br />
