/**
* 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:
*
* <pre>{@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;
* }
* }</pre>
*
* <p>Without additional type information, the serialized JSON is ambiguous. Is the bottom shape in
* this drawing a rectangle or a diamond?
*
* <pre>{@code
* {
* "bottomShape": {
* "width": 10,
* "height": 5,
* "x": 0,
* "y": 0
* },
* "topShape": {
* "radius": 2,
* "x": 4,
* "y": 1
* }
* }
* }</pre>
*
* This class addresses this problem by adding type information to the serialized JSON and honoring
* that type information when the JSON is deserialized:
*
* <pre>{@code
* {
* "bottomShape": {
* "type": "Diamond",
* "width": 10,
* "height": 5,
* "x": 0,
* "y": 0
* },
* "topShape": {
* "type": "Circle",
* "radius": 2,
* "x": 4,
* "y": 1
* }
* }
* }</pre>
*
* Both the type field name ({@code "type"}) and the type labels ({@code "Rectangle"}) are
* configurable.
*
* <h2>Registering Types</h2>
*
* 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.
*
* <pre>{@code
* RuntimeTypeAdapterFactory<Shape> shapeAdapterFactory
* = RuntimeTypeAdapterFactory.of(Shape.class, "type");
* }</pre>
*
* 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.
*
* <pre>{@code
* shapeAdapterFactory.registerSubtype(Rectangle.class, "Rectangle");
* shapeAdapterFactory.registerSubtype(Circle.class, "Circle");
* shapeAdapterFactory.registerSubtype(Diamond.class, "Diamond");
* }</pre>
*
* Finally, register the type adapter factory in your application's GSON builder:
*
* <pre>{@code
* Gson gson = new GsonBuilder()
* .registerTypeAdapterFactory(shapeAdapterFactory)
* .create();
* }</pre>
*
* Like {@code GsonBuilder}, this API supports chaining:
*
* <pre>{@code
* RuntimeTypeAdapterFactory<Shape> shapeAdapterFactory = RuntimeTypeAdapterFactory.of(Shape.class)
* .registerSubtype(Rectangle.class)
* .registerSubtype(Circle.class)
* .registerSubtype(Diamond.class);
* }</pre>
*
* <h2>Serialization and deserialization</h2>
*
* In order to serialize and deserialize a polymorphic object, you must specify the base type
* explicitly.
*
* <pre>{@code
* Diamond diamond = new Diamond();
* String json = gson.toJson(diamond, Shape.class);
* }</pre>
*
* And then:
*
* <pre>{@code
* Shape shape = gson.fromJson(json, Shape.class);
* }</pre>
