+ * a third-party library that you do not have source-code of. In such cases, you should define an
+ * instance creator for the class. Implementations of this interface should be registered with
+ * {@link GsonBuilder#registerTypeAdapter(Type, Object)} method before Gson will be able to use
+ * them.
+ * Let us look at an example where defining an InstanceCreator might be useful. The

+ *
+ *
+ * public class Id<T> {
+ * private final Class<T> clazz;

+ * constructor as follows:
+ *
+ *
+ * private Id() {
+ * this(Object.class, 0L);

+ * However, let us assume that the developer does not have access to the source-code of the

+ * can solve this problem by defining an {@code InstanceCreator} for {@code Id}:
+ *
+ *
+ * class IdInstanceCreator implements InstanceCreator<Id> {
+ * public Id createInstance(Type type) {
+ * return new Id(Object.class, 0L);
+ * }
+ * }
+ *
+ *
+ * Note that it does not matter what the fields of the created instance contain since Gson will
+ * overwrite them with the deserialized values specified in Json. You should also ensure that a
+ * new object is returned, not a common object since its fields will be overwritten.
+ * The developer will need to register {@code IdInstanceCreator} with Gson as follows:
+ *
+ *
+ * Gson gson = new GsonBuilder().registerTypeAdapter(Id.class, new IdInstanceCreator()).create();

+ * Interface representing a custom deserializer for Json. You should write a custom
+ * deserializer, if you are not happy with the default deserialization done by Gson. You will
+ * also need to register this deserializer through
+ * {@link GsonBuilder#registerTypeAdapter(Type, Object)}.
+ *
+ * Let us look at example where defining a deserializer will be useful. The {@code Id} class
+ * defined below has two fields: {@code clazz} and {@code value}.
+ *
+ *
+ * public class Id<T> {
+ * private final Class<T> clazz;

+ * this.value = value;
+ * }
+ * public long getValue() {
+ * return value;
+ * }
+ * }
+ *
+ *
+ * The default deserialization of {@code Id(com.foo.MyObject.class, 20L)} will require the
+ * Json string to be {"clazz":com.foo.MyObject,"value":20}
. Suppose, you already know
+ * the type of the field that the {@code Id} will be deserialized into, and hence just want to
+ * deserialize it from a Json string {@code 20}. You can achieve that by writing a custom
+ * deserializer:
+ *
+ *
+ * class IdDeserializer implements JsonDeserializer<Id>() {
+ * public Id deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context)
+ * throws JsonParseException {
+ * return new Id((Class)typeOfT, id.getValue());
+ * }
+ *
+ *
+ * You will also need to register {@code IdDeserializer} with Gson as follows:
+ *
+ *
+ * Gson gson = new GsonBuilder().registerTypeAdapter(Id.class, new IdDeserializer()).create();
+ *
+ *
+ * New applications should prefer {@link TypeAdapter}, whose streaming API
+ * is more efficient than this interface's tree API.
+ *
+ * @author Inderjeet Singh
+ * @author Joel Leitch
+ *
+ * @param type for which the deserializer is being registered. It is possible that a
+ * deserializer may be asked to deserialize a specific generic type of the T.
+ */

+ * for any non-trivial field of the returned object. However, you should never invoke it on the
+ * the same type passing {@code json} since that will cause an infinite loop (Gson will call your
+ * call-back method again).

+/**
+ * Converts Java objects to and from JSON.
+ *
+ * Defining a type's JSON form
+ * By default Gson converts application classes to JSON using its built-in type
+ * adapters. If Gson's default JSON conversion isn't appropriate for a type,
+ * extend this class to customize the conversion. Here's an example of a type
+ * adapter for an (X,Y) coordinate point: {@code
+ *
+ * public class PointAdapter extends TypeAdapter {
+ * public Point read(JsonReader reader) throws IOException {
+ * if (reader.peek() == JsonToken.NULL) {
+ * reader.nextNull();
+ * return null;
+ * }
+ * String xy = reader.nextString();
+ * String[] parts = xy.split(",");
+ * int x = Integer.parseInt(parts[0]);
+ * int y = Integer.parseInt(parts[1]);
+ * return new Point(x, y);
+ * }
+ * public void write(JsonWriter writer, Point value) throws IOException {
+ * if (value == null) {
+ * writer.nullValue();
+ * return;
+ * }
+ * String xy = value.getX() + "," + value.getY();
+ * writer.value(xy);
+ * }
+ * }}
+ * With this type adapter installed, Gson will convert {@code Points} to JSON as
+ * strings like {@code "5,8"} rather than objects like {@code {"x":5,"y":8}}. In
+ * this case the type adapter binds a rich Java class to a compact JSON value.
+ *
+ * The {@link #read(JsonReader) read()} method must read exactly one value
+ * and {@link #write(JsonWriter,Object) write()} must write exactly one value.
+ * For primitive types this is means readers should make exactly one call to
+ * {@code nextBoolean()}, {@code nextDouble()}, {@code nextInt()}, {@code
+ * nextLong()}, {@code nextString()} or {@code nextNull()}. Writers should make
+ * exactly one call to one of value()
or nullValue()
.
+ * For arrays, type adapters should start with a call to {@code beginArray()},
+ * convert all elements, and finish with a call to {@code endArray()}. For
+ * objects, they should start with {@code beginObject()}, convert the object,
+ * and finish with {@code endObject()}. Failing to convert a value or converting
+ * too many values may cause the application to crash.
+ *
+ *
Type adapters should be prepared to read null from the stream and write it
+ * to the stream. Alternatively, they should use {@link #nullSafe()} method while
+ * registering the type adapter with Gson. If your {@code Gson} instance
+ * has been configured to {@link GsonBuilder#serializeNulls()}, these nulls will be
+ * written to the final document. Otherwise the value (and the corresponding name
+ * when writing to a JSON object) will be omitted automatically. In either case
+ * your type adapter must handle null.
+ *
+ *
To use a custom type adapter with Gson, you must register it with a
+ * {@link GsonBuilder}:
{@code
+ *
+ * GsonBuilder builder = new GsonBuilder();
+ * builder.registerTypeAdapter(Point.class, new PointAdapter());
+ * // if PointAdapter didn't check for nulls in its read/write methods, you should instead use
+ * // builder.registerTypeAdapter(Point.class, new PointAdapter().nullSafe());
+ * ...
+ * Gson gson = builder.create();
+ * }
+ *
+ * @since 2.1
+ */
+// non-Javadoc:
+//
+// JSON Conversion
+// A type adapter registered with Gson is automatically invoked while serializing
+// or deserializing JSON. However, you can also use type adapters directly to serialize
+// and deserialize JSON. Here is an example for deserialization:
{@code
+//
+// String json = "{'origin':'0,0','points':['1,2','3,4']}";
+// TypeAdapter graphAdapter = gson.getAdapter(Graph.class);
+// Graph graph = graphAdapter.fromJson(json);
+// }
+// And an example for serialization: {@code
+//
+// Graph graph = new Graph(...);
+// TypeAdapter graphAdapter = gson.getAdapter(Graph.class);
+// String json = graphAdapter.toJson(graph);
+// }
+//
+// Type adapters are type-specific . For example, a {@code
+// TypeAdapter} can convert {@code Date} instances to JSON and JSON to
+// instances of {@code Date}, but cannot convert any other types.

+/**
+ * Creates type adapters for set of related types. Type adapter factories are
+ * most useful when several types share similar structure in their JSON form.
+ *
+ * Example: Converting enums to lowercase
+ * In this example, we implement a factory that creates type adapters for all
+ * enums. The type adapters will write enums in lowercase, despite the fact
+ * that they're defined in {@code CONSTANT_CASE} in the corresponding Java
+ * model: {@code
+ *
+ * public class LowercaseEnumTypeAdapterFactory implements TypeAdapter.Factory {
+ * public TypeAdapter create(Gson gson, TypeToken type) {
+ * Class rawType = (Class) type.getRawType();
+ * if (!rawType.isEnum()) {
+ * return null;
+ * }
+ *
+ * final Map lowercaseToConstant = new HashMap();
+ * for (T constant : rawType.getEnumConstants()) {
+ * lowercaseToConstant.put(toLowercase(constant), constant);
+ * }
+ *
+ * return new TypeAdapter() {
+ * public void write(JsonWriter out, T value) throws IOException {
+ * if (value == null) {
+ * out.nullValue();
+ * } else {
+ * out.value(toLowercase(value));
+ * }
+ * }
+ *
+ * public T read(JsonReader reader) throws IOException {
+ * if (reader.peek() == JsonToken.NULL) {
+ * reader.nextNull();
+ * return null;
+ * } else {
+ * return lowercaseToConstant.get(reader.nextString());
+ * }
+ * }
+ * };
+ * }
+ *
+ * private String toLowercase(Object o) {
+ * return o.toString().toLowerCase(Locale.US);
+ * }
+ * }
+ * }
+ *
+ * Type adapter factories select which types they provide type adapters
+ * for. If a factory cannot support a given type, it must return null when
+ * that type is passed to {@link #create}. Factories should expect {@code
+ * create()} to be called on them for many types and should return null for
+ * most of those types. In the above example the factory returns null for
+ * calls to {@code create()} where {@code type} is not an enum.
+ *
+ *
A factory is typically called once per type, but the returned type
+ * adapter may be used many times. It is most efficient to do expensive work
+ * like reflection in {@code create()} so that the type adapter's {@code
+ * read()} and {@code write()} methods can be very fast. In this example the
+ * mapping from lowercase name to enum value is computed eagerly.
+ *
+ *
As with type adapters, factories must be registered with a {@link
+ * com.google.gson.GsonBuilder} for them to take effect:
{@code
+ *
+ * GsonBuilder builder = new GsonBuilder();
+ * builder.registerTypeAdapterFactory(new LowercaseEnumTypeAdapterFactory());
+ * ...
+ * Gson gson = builder.create();
+ * }
+ * If multiple factories support the same type, the factory registered earlier
+ * takes precedence.
+ *
+ * Example: composing other type adapters
+ * In this example we implement a factory for Guava's {@code Multiset}
+ * collection type. The factory can be used to create type adapters for
+ * multisets of any element type: the type adapter for {@code
+ * Multiset} is different from the type adapter for {@code
+ * Multiset}.
+ *
+ * The type adapter delegates to another type adapter for the
+ * multiset elements. It figures out the element type by reflecting on the
+ * multiset's type token. A {@code Gson} is passed in to {@code create} for
+ * just this purpose:
{@code
+ *
+ * public class MultisetTypeAdapterFactory implements TypeAdapter.Factory {
+ * public TypeAdapter create(Gson gson, TypeToken typeToken) {
+ * Type type = typeToken.getType();
+ * if (typeToken.getRawType() != Multiset.class
+ * || !(type instanceof ParameterizedType)) {
+ * return null;
+ * }
+ *
+ * Type elementType = ((ParameterizedType) type).getActualTypeArguments()[0];
+ * TypeAdapter> elementAdapter = gson.getAdapter(TypeToken.get(elementType));
+ * return (TypeAdapter) newMultisetAdapter(elementAdapter);
+ * }
+ *
+ * private TypeAdapter> newMultisetAdapter(
+ * final TypeAdapter elementAdapter) {
+ * return new TypeAdapter>() {
+ * public void write(JsonWriter out, Multiset value) throws IOException {
+ * if (value == null) {
+ * out.nullValue();
+ * return;
+ * }
+ *
+ * out.beginArray();
+ * for (Multiset.Entry entry : value.entrySet()) {
+ * out.value(entry.getCount());
+ * elementAdapter.write(out, entry.getElement());
+ * }
+ * out.endArray();
+ * }
+ *
+ * public Multiset read(JsonReader in) throws IOException {
+ * if (in.peek() == JsonToken.NULL) {
+ * in.nextNull();
+ * return null;
+ * }
+ *
+ * Multiset result = LinkedHashMultiset.create();
+ * in.beginArray();
+ * while (in.hasNext()) {
+ * int count = in.nextInt();
+ * E element = elementAdapter.read(in);
+ * result.add(element, count);
+ * }
+ * in.endArray();
+ * return result;
+ * }
+ * };
+ * }
+ * }
+ * }
+ * Delegating from one type adapter to another is extremely powerful; it's
+ * the foundation of how Gson converts Java objects and collections. Whenever
+ * possible your factory should retrieve its delegate type adapter in the
+ * {@code create()} method; this ensures potentially-expensive type adapter
+ * creation happens only once.
+ *
+ * @since 2.1
+ */
+public interface TypeAdapterFactory {
+
+ /**
+ * Returns a type adapter for {@code type}, or null if this factory doesn't
+ * support {@code type}.
