+    The default implementations of this method is an <a

+    The default implementations of this method is an <a

+    relation</a>:
+      <ul>
+      <li>It is reflexive: for any instance <code>x</code> of type <code>Any</code>,

+      if <code>y.equals(x)</code> returns <code>true</code>.</li>
