FINAL

Done.

Why do you need friends?

[Marijn Kruisselbrink, 2014/08/19 18:55:14]

because WebGeofencingRegion::to and constTo create null instances before
assigning a value. But there really is no reason for that constructor to be
private, which eliminates the need for the friend.

+
+    WebCircularRegion() { }
+
+    WebCircularRegionPrivate* privateData() const;
+};
+
+} // namespace blink
+
+#endif // WebCircularRegion_h
