+/**
+ * Adapts values whose runtime type may differ from their 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 width;
+ * 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);
+ * }
