+// An implementation of ObjectWriter that automatically sets the
+// gmock expectations for the response to a method. Every method
+// returns the object itself for chaining.
+//
+// Usage:
+//   // Setup
+//   MockObjectWriter mock;
+//   ExpectingObjectWriter ow(&mock);
+//
+//   // Set expectation
+//   ow.StartObject("")
+//       ->RenderString("key", "value")
+//     ->EndObject();
+//
+//   // Actual testing
+//   mock.StartObject(StringPiece())
+//         ->RenderString("key", "value")
+//       ->EndObject();
