declaration type. This + * is necessary when a field's type is not the same type that GSON should create + * when deserializing that field. For example, consider these types: + * 
   {@code
+ *   abstract class Shape {
+ *     int x;
+ *     int y;
+ *   }
+ *   class Circle extends Shape {
+ *     int radius;
+ *   }
+ *   class Rectangle extends Shape {
+ *     int width;
+ *     int height;
+ *   }
+ *   class Diamond extends Shape {

+ *     int height;
+ *   }
+ *   class Drawing {
+ *     Shape bottomShape;
+ *     Shape topShape;
+ *   }
+ * }
+ *

Without additional type information, the serialized JSON is ambiguous. Is + * the bottom shape in this drawing a rectangle or a diamond? 

   {@code
+ *   {
+ *     "bottomShape": {
+ *       "width": 10,
+ *       "height": 5,
+ *       "x": 0,
+ *       "y": 0
+ *     },
+ *     "topShape": {
+ *       "radius": 2,
+ *       "x": 4,
+ *       "y": 1
+ *     }
+ *   }}
+ * This class addresses this problem by adding type information to the + * serialized JSON and honoring that type information when the JSON is + * deserialized: 
   {@code
+ *   {
+ *     "bottomShape": {
+ *       "type": "Diamond",
+ *       "width": 10,
+ *       "height": 5,
+ *       "x": 0,
+ *       "y": 0
+ *     },
+ *     "topShape": {
+ *       "type": "Circle",
+ *       "radius": 2,
+ *       "x": 4,
+ *       "y": 1
+ *     }
+ *   }}
+ * Both the type field name ({@code "type"}) and the type labels ({@code + * "Rectangle"}) are configurable. + * + *

Registering Types

+ * Create a {@code RuntimeTypeAdapterFactory} by passing the base type and type field + * name to the {@link #of} factory method. If you don't supply an explicit type + * field name, {@code "type"} will be used. 
   {@code
+ *   RuntimeTypeAdapterFactory shapeAdapterFactory
+ *       = RuntimeTypeAdapterFactory.of(Shape.class, "type");
+ * }
+ * Next register all of your subtypes. Every subtype must be explicitly + * registered. This protects your application from injection attacks. If you + * don't supply an explicit type label, the type's simple name will be used. + * 
   {@code
+ *   shapeAdapterFactory.registerSubtype(Rectangle.class, "Rectangle");
+ *   shapeAdapterFactory.registerSubtype(Circle.class, "Circle");
+ *   shapeAdapterFactory.registerSubtype(Diamond.class, "Diamond");
+ * }
+ * Finally, register the type adapter factory in your application's GSON builder: + * 
   {@code
+ *   Gson gson = new GsonBuilder()
+ *       .registerTypeAdapterFactory(shapeAdapterFactory)
+ *       .create();
+ * }
+ * Like {@code GsonBuilder}, this API supports chaining: 
   {@code
+ *   RuntimeTypeAdapterFactory shapeAdapterFactory = RuntimeTypeAdapterFactory.of(Shape.class)
+ *       .registerSubtype(Rectangle.class)
+ *       .registerSubtype(Circle.class)
+ *       .registerSubtype(Diamond.class);
