/**
* A strategy (or policy) definition that is used to decide whether or not a field or top-level
* class should be serialized or deserialized as part of the JSON output/input. For serialization,
* if the {@link #shouldSkipClass(Class)} method returns true then that class or field type
* will not be part of the JSON output. For deserialization, if {@link #shouldSkipClass(Class)}
* returns true, then it will not be set as part of the Java object structure.
*
* <p>The following are a few examples that shows how you can use this exclusion mechanism.
*
* <p><strong>Exclude fields and objects based on a particular class type:</strong>
* <pre class="code">
* private static class SpecificClassExclusionStrategy implements ExclusionStrategy {
* private final Class&lt;?&gt; excludedThisClass;
*
* public SpecificClassExclusionStrategy(Class&lt;?&gt; excludedThisClass) {
* this.excludedThisClass = excludedThisClass;
* }
*
* public boolean shouldSkipClass(Class&lt;?&gt; clazz) {
* return excludedThisClass.equals(clazz);
* }
*
* public boolean shouldSkipField(FieldAttributes f) {
* return excludedThisClass.equals(f.getDeclaredClass());
* }
* }
* </pre>
*
* <p><strong>Excludes fields and objects based on a particular annotation:</strong>
* <pre class="code">
* public &#64;interface FooAnnotation {
* // some implementation here
* }
*
* // Excludes any field (or class) that is tagged with an "&#64;FooAnnotation"
* private static class FooAnnotationExclusionStrategy implements ExclusionStrategy {
* public boolean shouldSkipClass(Class&lt;?&gt; clazz) {
* return clazz.getAnnotation(FooAnnotation.class) != null;
* }
*
* public boolean shouldSkipField(FieldAttributes f) {
* return f.getAnnotation(FooAnnotation.class) != null;
* }
* }
* </pre>
*
* <p>Now if you want to configure {@code Gson} to use a user defined exclusion strategy, then
* the {@code GsonBuilder} is required. The following is an example of how you can use the
* {@code GsonBuilder} to configure Gson to use one of the above sample:
* <pre class="code">
* ExclusionStrategy excludeStrings = new UserDefinedExclusionStrategy(String.class);
* Gson gson = new GsonBuilder()
* .setExclusionStrategies(excludeStrings)
* .create();
* </pre>
*
* <p>For certain model classes, you may only want to serialize a field, but exclude it for
* deserialization. To do that, you can write an {@code ExclusionStrategy} as per normal;
* however, you would register it with the
* {@link GsonBuilder#addDeserializationExclusionStrategy(ExclusionStrategy)} method.
* For example:
* <pre class="code">
* ExclusionStrategy excludeStrings = new UserDefinedExclusionStrategy(String.class);
* Gson gson = new GsonBuilder()
* .addDeserializationExclusionStrategy(excludeStrings)
* .create();
* </pre>
*

* @author Joel Leitch
*
* @see GsonBuilder#setExclusionStrategies(ExclusionStrategy...)
* @see GsonBuilder#addDeserializationExclusionStrategy(ExclusionStrategy)
* @see GsonBuilder#addSerializationExclusionStrategy(ExclusionStrategy)

/**
* This is the main class for using Gson. Gson is typically used by first constructing a
* Gson instance and then invoking {@link #toJson(Object)} or {@link #fromJson(String, Class)}
* methods on it. Gson instances are Thread-safe so you can reuse them freely across multiple
* threads.
*
* <p>You can create a Gson instance by invoking {@code new Gson()} if the default configuration
* is all you need. You can also use {@link GsonBuilder} to build a Gson instance with various
* configuration options such as versioning support, pretty printing, custom
* {@link JsonSerializer}s, {@link JsonDeserializer}s, and {@link InstanceCreator}s.</p>
*
* <p>Here is an example of how Gson is used for a simple Class:
*
* <pre>
* Gson gson = new Gson(); // Or use new GsonBuilder().create();
* MyType target = new MyType();
* String json = gson.toJson(target); // serializes target to Json
* MyType target2 = gson.fromJson(json, MyType.class); // deserializes json into target2
* </pre>
*
* <p>If the object that your are serializing/deserializing is a {@code ParameterizedType}
* (i.e. contains at least one type parameter and may be an array) then you must use the
* {@link #toJson(Object, Type)} or {@link #fromJson(String, Type)} method. Here is an
* example for serializing and deserializing a {@code ParameterizedType}:
*
* <pre>
* Type listType = new TypeToken&lt;List&lt;String&gt;&gt;() {}.getType();
* List&lt;String&gt; target = new LinkedList&lt;String&gt;();
* target.add("blah");
*
* Gson gson = new Gson();
* String json = gson.toJson(target, listType);
* List&lt;String&gt; target2 = gson.fromJson(json, listType);
* </pre>

* generated JSON is empty, the field is kept. You can configure Gson to serialize null values
* by setting {@link GsonBuilder#serializeNulls()}.</li>
* <li>Gson provides default serialization and deserialization for Enums, {@link Map},
* {@link java.net.URL}, {@link java.net.URI}, {@link java.util.Locale}, {@link java.util.Date},
* {@link BigDecimal}, and {@link BigInteger} classes. If you would prefer
* to change the default representation, you can do so by registering a type adapter through
* {@link GsonBuilder#registerTypeAdapter(Type, Object)}. </li>
* <li>The default Date format is same as {@link DateFormat#DEFAULT}. This format
* ignores the millisecond portion of the date during serialization. You can change
* this by invoking {@link GsonBuilder#setDateFormat(int)} or
* {@link GsonBuilder#setDateFormat(String)}. </li>
* <li>By default, Gson ignores the {@link com.sobot.gson.annotations.Expose} annotation.

/**
* This method is used to get an alternate type adapter for the specified type. This is used
* to access a type adapter that is overridden by a {@link TypeAdapterFactory} that you
* may have registered. This features is typically used when you want to register a type
* adapter that does a little bit of work but then delegates further processing to the Gson
* default type adapter. Here is an example:
* <p>Let's say we want to write a type adapter that counts the number of objects being read
* from or written to JSON. We can achieve this by writing a type adapter factory that uses
* the <code>getDelegateAdapter</code> method:
* <pre> {@code
* class StatsTypeAdapterFactory implements TypeAdapterFactory {
* public int numReads = 0;
* public int numWrites = 0;
* public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type) {
* final TypeAdapter<T> delegate = gson.getDelegateAdapter(this, type);
* return new TypeAdapter<T>() {
* public void write(JsonWriter out, T value) throws IOException {
* ++numWrites;
* delegate.write(out, value);
* }
* public T read(JsonReader in) throws IOException {
* ++numReads;
* return delegate.read(in);
* }
* };
* }
* }
* } </pre>
* This factory can now be used like this:
* <pre> {@code
* StatsTypeAdapterFactory stats = new StatsTypeAdapterFactory();
* Gson gson = new GsonBuilder().registerTypeAdapterFactory(stats).create();
* // Call gson.toJson() and fromJson methods on objects
* System.out.println("Num JSON reads" + stats.numReads);
* System.out.println("Num JSON writes" + stats.numWrites);
* }</pre>
* Note that this call will skip all factories registered before {@code skipPast}. In case of
* multiple TypeAdapterFactories registered it is up to the caller of this function to insure
* that the order of registration does not prevent this method from reaching a factory they
* would expect to reply from this call.
* Note that since you can not override type adapter factories for String and Java primitive
* types, our stats factory will not count the number of String or primitives that will be
* read or written.
* @param skipPast The type adapter factory that needs to be skipped while searching for
* a matching type adapter. In most cases, you should just pass <i>this</i> (the type adapter
* factory from where {@code getDelegateAdapter} method is being invoked).
* @param type Type for which the delegate adapter is being searched for.

* then be serialized as a {@link JsonObject}.
*

* Gson gson = new GsonBuilder()
* .register(Point.class, new MyPointTypeAdapter())
* .enableComplexMapKeySerialization()
* .create();
*

* {
* "(5,6)": "a",
* "(8,8)": "b"
* }
* }</pre>
*
* <h3>Maps as JSON arrays</h3>
* For this case, assume that a type adapter was NOT registered for some
* {@code Point} class, but rather the default Gson serialization is applied.
* In this case, some {@code new Point(2,3)} would serialize as {@code
* {"x":2,"y":5}}.
*
* <p>Given the assumption above, a {@code Map<Point, String>} will be
* serialize as an array of arrays (can be viewed as an entry set of pairs).
*
* <p>Below is an example of serializing complex types as JSON arrays:
* <pre> {@code
* Gson gson = new GsonBuilder()

*
* Map<Point, String> original = new LinkedHashMap<>();
* original.put(new Point(5, 6), "a");
* original.put(new Point(8, 8), "b");
* System.out.println(gson.toJson(original, type));
* }
* </pre>

/**
* This interface is implemented to create instances of a class that does not define a no-args
* constructor. If you can modify the class, you should instead add a private, or public
* no-args constructor. However, that is not possible for library classes, such as JDK classes, or
* 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.
* <p>Let us look at an example where defining an InstanceCreator might be useful. The
* {@code Id} class defined below does not have a default no-args constructor.</p>
*
* <pre>
* public class Id&lt;T&gt; {
* private final Class&lt;T&gt; clazz;
* private final long value;
* public Id(Class&lt;T&gt; clazz, long value) {
* this.clazz = clazz;
* this.value = value;
* }
* }
* </pre>
*
* <p>If Gson encounters an object of type {@code Id} during deserialization, it will throw an
* exception. The easiest way to solve this problem will be to add a (public or private) no-args
* constructor as follows:</p>
*
* <pre>
* private Id() {
* this(Object.class, 0L);
* }
* </pre>
*
* <p>However, let us assume that the developer does not have access to the source-code of the
* {@code Id} class, or does not want to define a no-args constructor for it. The developer
* can solve this problem by defining an {@code InstanceCreator} for {@code Id}:</p>
*
* <pre>
* class IdInstanceCreator implements InstanceCreator&lt;Id&gt; {
* public Id createInstance(Type type) {
* return new Id(Object.class, 0L);
* }
* }
* </pre>
*
* <p>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
* <i>new</i> 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:</p>
*
* <pre>
* Gson gson = new GsonBuilder().registerTypeAdapter(Id.class, new IdInstanceCreator()).create();
* </pre>
*
* @param <T> the type of object that will be created by this implementation.

* <pre>
* Gson gson = new GsonBuilder().registerTypeAdapter(Id.class, new IdSerializer()).create();
* </pre>
*
* <p>New applications should prefer {@link TypeAdapter}, whose streaming API

/**
* Converts Java objects to and from JSON.
*
* <h3>Defining a type's JSON form</h3>
* 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: <pre> {@code
*
* public class PointAdapter extends TypeAdapter<Point> {
* 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);
* }
* }}</pre>
* 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.
*
* <p>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 <code>value()</code> or <code>nullValue()</code>.
* 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.
*
* <p>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.
*
* <p>To use a custom type adapter with Gson, you must <i>register</i> it with a
* {@link GsonBuilder}: <pre> {@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();
* }</pre>
*
* @since 2.1

//
// <h3>JSON Conversion</h3>
// <p>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: <pre> {@code
//
// String json = "{'origin':'0,0','points':['1,2','3,4']}";
// TypeAdapter<Graph> graphAdapter = gson.getAdapter(Graph.class);
// Graph graph = graphAdapter.fromJson(json);
// }</pre>
// And an example for serialization: <pre> {@code
//
// Graph graph = new Graph(...);
// TypeAdapter<Graph> graphAdapter = gson.getAdapter(Graph.class);
// String json = graphAdapter.toJson(graph);
// }</pre>
//
// <p>Type adapters are <strong>type-specific</strong>. For example, a {@code
// TypeAdapter<Date>} 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.
*
* <h3>Example: Converting enums to lowercase</h3>
* 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: <pre> {@code
*
* public class LowercaseEnumTypeAdapterFactory implements TypeAdapterFactory {
* public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type) {
* Class<T> rawType = (Class<T>) type.getRawType();
* if (!rawType.isEnum()) {
* return null;
* }
*
* final Map<String, T> lowercaseToConstant = new HashMap<>();
* for (T constant : rawType.getEnumConstants()) {
* lowercaseToConstant.put(toLowercase(constant), constant);
* }
*
* return new TypeAdapter<T>() {
* 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);
* }
* }
* }</pre>
*
* <p>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.
*
* <p>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.
*
* <p>As with type adapters, factories must be <i>registered</i> with a {@link
* com.sobot.gson.GsonBuilder} for them to take effect: <pre> {@code
*
* GsonBuilder builder = new GsonBuilder();
* builder.registerTypeAdapterFactory(new LowercaseEnumTypeAdapterFactory());
* ...
* Gson gson = builder.create();
* }</pre>
* If multiple factories support the same type, the factory registered earlier
* takes precedence.
*
* <h3>Example: composing other type adapters</h3>
* 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<String>} is different from the type adapter for {@code
* Multiset<URL>}.
*
* <p>The type adapter <i>delegates</i> 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: <pre> {@code
*
* public class MultisetTypeAdapterFactory implements TypeAdapterFactory {
* public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> 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<T>) newMultisetAdapter(elementAdapter);
* }
*
* private <E> TypeAdapter<Multiset<E>> newMultisetAdapter(
* final TypeAdapter<E> elementAdapter) {
* return new TypeAdapter<Multiset<E>>() {
* public void write(JsonWriter out, Multiset<E> value) throws IOException {
* if (value == null) {
* out.nullValue();
* return;
* }
*
* out.beginArray();
* for (Multiset.Entry<E> entry : value.entrySet()) {
* out.value(entry.getCount());
* elementAdapter.write(out, entry.getElement());
* }
* out.endArray();
* }
*
* public Multiset<E> read(JsonReader in) throws IOException {
* if (in.peek() == JsonToken.NULL) {
* in.nextNull();
* return null;
* }
*
* Multiset<E> 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;
* }
* };
* }
* }
* }</pre>
* 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.

/**
* Adapts maps to either JSON objects or JSON arrays.
*
* <h3>Maps as JSON objects</h3>
* For primitive keys or when complex map key serialization is not enabled, this
* converts Java {@link Map Maps} to JSON Objects. This requires that map keys
* can be serialized as strings; this is insufficient for some key types. For
* example, consider a map whose keys are points on a grid. The default JSON
* form encodes reasonably: <pre> {@code
* Map<Point, String> original = new LinkedHashMap<>();
* original.put(new Point(5, 6), "a");
* original.put(new Point(8, 8), "b");
* System.out.println(gson.toJson(original, type));
* }</pre>
* The above code prints this JSON object:<pre> {@code
* {
* "(5,6)": "a",
* "(8,8)": "b"
* }
* }</pre>
* But GSON is unable to deserialize this value because the JSON string name is
* just the {@link Object#toString() toString()} of the map key. Attempting to
* convert the above JSON to an object fails with a parse exception:
* <pre>com.sobot.gson.JsonParseException: Expecting object found: "(5,6)"
* at com.sobot.gson.JsonObjectDeserializationVisitor.visitFieldUsingCustomHandler
* at com.sobot.gson.ObjectNavigator.navigateClassFields
* ...</pre>
*
* <h3>Maps as JSON arrays</h3>
* An alternative approach taken by this type adapter when it is required and
* complex map key serialization is enabled is to encode maps as arrays of map
* entries. Each map entry is a two element array containing a key and a value.
* This approach is more flexible because any type can be used as the map's key;
* not just strings. But it's also less portable because the receiver of such
* JSON must be aware of the map entry convention.
*
* <p>Register this adapter when you are creating your GSON instance.
* <pre> {@code
* Gson gson = new GsonBuilder()
* .registerTypeAdapter(Map.class, new MapAsArrayTypeAdapter())
* .create();
* }</pre>
* This will change the structure of the JSON emitted by the code above. Now we
* get an array. In this case the arrays elements are map entries:
* <pre> {@code
* [
* [
* {
* "x": 5,
* "y": 6
* },
* "a",
* ],
* [
* {
* "x": 8,
* "y": 8
* },
* "b"
* ]
* ]
* }</pre>
* This format will serialize and deserialize just fine as long as this adapter
* is registered.

/**
* Reads a JSON (<a href="http://www.ietf.org/rfc/rfc7159.txt">RFC 7159</a>)
* encoded value as a stream of tokens. This stream includes both literal
* values (strings, numbers, booleans, and nulls) as well as the begin and
* end delimiters of objects and arrays. The tokens are traversed in
* depth-first order, the same order that they appear in the JSON document.
* Within JSON objects, name/value pairs are represented by a single token.
*
* <h3>Parsing JSON</h3>
* To create a recursive descent parser for your own JSON streams, first create
* an entry point method that creates a {@code JsonReader}.
*
* <p>Next, create handler methods for each structure in your JSON text. You'll
* need a method for each object type and for each array type.
* <ul>
* <li>Within <strong>array handling</strong> methods, first call {@link
* #beginArray} to consume the array's opening bracket. Then create a
* while loop that accumulates values, terminating when {@link #hasNext}
* is false. Finally, read the array's closing bracket by calling {@link
* #endArray}.
* <li>Within <strong>object handling</strong> methods, first call {@link
* #beginObject} to consume the object's opening brace. Then create a
* while loop that assigns values to local variables based on their name.
* This loop should terminate when {@link #hasNext} is false. Finally,
* read the object's closing brace by calling {@link #endObject}.
* </ul>
* <p>When a nested object or array is encountered, delegate to the
* corresponding handler method.
*
* <p>When an unknown name is encountered, strict parsers should fail with an
* exception. Lenient parsers should call {@link #skipValue()} to recursively
* skip the value's nested tokens, which may otherwise conflict.
*
* <p>If a value may be null, you should first check using {@link #peek()}.
* Null literals can be consumed using either {@link #nextNull()} or {@link
* #skipValue()}.
*
* <h3>Example</h3>
* Suppose we'd like to parse a stream of messages such as the following: <pre> {@code
* [
* {
* "id": 912345678901,
* "text": "How do I read a JSON stream in Java?",
* "geo": null,
* "user": {
* "name": "json_newb",
* "followers_count": 41
* }
* },
* {
* "id": 912345678902,
* "text": "@json_newb just use JsonReader!",
* "geo": [50.454722, -104.606667],
* "user": {
* "name": "jesse",
* "followers_count": 2
* }
* }
* ]}</pre>
* This code implements the parser for the above structure: <pre> {@code
*
* public List<Message> readJsonStream(InputStream in) throws IOException {
* JsonReader reader = new JsonReader(new InputStreamReader(in, "UTF-8"));
* try {
* return readMessagesArray(reader);
* } finally {
* reader.close();
* }
* }
*
* public List<Message> readMessagesArray(JsonReader reader) throws IOException {
* List<Message> messages = new ArrayList<>();
*
* reader.beginArray();
* while (reader.hasNext()) {
* messages.add(readMessage(reader));
* }
* reader.endArray();
* return messages;
* }
*
* public Message readMessage(JsonReader reader) throws IOException {
* long id = -1;
* String text = null;
* User user = null;
* List<Double> geo = null;
*
* reader.beginObject();
* while (reader.hasNext()) {
* String name = reader.nextName();
* if (name.equals("id")) {
* id = reader.nextLong();
* } else if (name.equals("text")) {
* text = reader.nextString();
* } else if (name.equals("geo") && reader.peek() != JsonToken.NULL) {
* geo = readDoublesArray(reader);
* } else if (name.equals("user")) {
* user = readUser(reader);
* } else {
* reader.skipValue();
* }
* }
* reader.endObject();
* return new Message(id, text, user, geo);
* }
*
* public List<Double> readDoublesArray(JsonReader reader) throws IOException {
* List<Double> doubles = new ArrayList<>();
*
* reader.beginArray();
* while (reader.hasNext()) {
* doubles.add(reader.nextDouble());
* }
* reader.endArray();
* return doubles;
* }
*
* public User readUser(JsonReader reader) throws IOException {
* String username = null;
* int followersCount = -1;
*
* reader.beginObject();
* while (reader.hasNext()) {
* String name = reader.nextName();
* if (name.equals("name")) {
* username = reader.nextString();
* } else if (name.equals("followers_count")) {
* followersCount = reader.nextInt();
* } else {
* reader.skipValue();
* }
* }
* reader.endObject();
* return new User(username, followersCount);
* }}</pre>
*
* <h3>Number Handling</h3>
* This reader permits numeric values to be read as strings and string values to
* be read as numbers. For example, both elements of the JSON array {@code
* [1, "1"]} may be read using either {@link #nextInt} or {@link #nextString}.
* This behavior is intended to prevent lossy numeric conversions: double is
* JavaScript's only numeric type and very large values like {@code
* 9007199254740993} cannot be represented exactly on that platform. To minimize
* precision loss, extremely large values should be written and read as strings
* in JSON.
*
* <h3 id="nonexecuteprefix">Non-Execute Prefix</h3>
* Web servers that serve private data using JSON may be vulnerable to <a
* href="http://en.wikipedia.org/wiki/JSON#Cross-site_request_forgery">Cross-site
* request forgery</a> attacks. In such an attack, a malicious site gains access
* to a private JSON file by executing it with an HTML {@code <script>} tag.
*
* <p>Prefixing JSON files with <code>")]}'\n"</code> makes them non-executable
* by {@code <script>} tags, disarming the attack. Since the prefix is malformed
* JSON, strict parsing fails when it is encountered. This class permits the
* non-execute prefix when {@link #setLenient(boolean) lenient parsing} is
* enabled.
*
* <p>Each {@code JsonReader} may be used to read a single JSON stream. Instances
* of this class are not thread safe.

/**
* Writes a JSON (<a href="http://www.ietf.org/rfc/rfc7159.txt">RFC 7159</a>)
* encoded value to a stream, one token at a time. The stream includes both
* literal values (strings, numbers, booleans and nulls) as well as the begin
* and end delimiters of objects and arrays.
*
* <h3>Encoding JSON</h3>
* To encode your data as JSON, create a new {@code JsonWriter}. Each JSON
* document must contain one top-level array or object. Call methods on the
* writer as you walk the structure's contents, nesting arrays and objects as
* necessary:
* <ul>
* <li>To write <strong>arrays</strong>, first call {@link #beginArray()}.
* Write each of the array's elements with the appropriate {@link #value}
* methods or by nesting other arrays and objects. Finally close the array
* using {@link #endArray()}.
* <li>To write <strong>objects</strong>, first call {@link #beginObject()}.
* Write each of the object's properties by alternating calls to
* {@link #name} with the property's value. Write property values with the
* appropriate {@link #value} method or by nesting other objects or arrays.
* Finally close the object using {@link #endObject()}.
* </ul>
*
* <h3>Example</h3>
* Suppose we'd like to encode a stream of messages such as the following: <pre> {@code
* [
* {
* "id": 912345678901,
* "text": "How do I stream JSON in Java?",
* "geo": null,
* "user": {
* "name": "json_newb",
* "followers_count": 41
* }
* },
* {
* "id": 912345678902,
* "text": "@json_newb just use JsonWriter!",
* "geo": [50.454722, -104.606667],
* "user": {
* "name": "jesse",
* "followers_count": 2
* }
* }
* ]}</pre>
* This code encodes the above structure: <pre> {@code
* public void writeJsonStream(OutputStream out, List<Message> messages) throws IOException {
* JsonWriter writer = new JsonWriter(new OutputStreamWriter(out, "UTF-8"));
* writer.setIndent(" ");
* writeMessagesArray(writer, messages);
* writer.close();
* }
*
* public void writeMessagesArray(JsonWriter writer, List<Message> messages) throws IOException {
* writer.beginArray();
* for (Message message : messages) {
* writeMessage(writer, message);
* }
* writer.endArray();
* }
*
* public void writeMessage(JsonWriter writer, Message message) throws IOException {
* writer.beginObject();
* writer.name("id").value(message.getId());
* writer.name("text").value(message.getText());
* if (message.getGeo() != null) {
* writer.name("geo");
* writeDoublesArray(writer, message.getGeo());
* } else {
* writer.name("geo").nullValue();
* }
* writer.name("user");
* writeUser(writer, message.getUser());
* writer.endObject();
* }
*
* public void writeUser(JsonWriter writer, User user) throws IOException {
* writer.beginObject();
* writer.name("name").value(user.getName());
* writer.name("followers_count").value(user.getFollowersCount());
* writer.endObject();
* }
*
* public void writeDoublesArray(JsonWriter writer, List<Double> doubles) throws IOException {
* writer.beginArray();
* for (Double value : doubles) {
* writer.value(value);
* }
* writer.endArray();
* }}</pre>
*
* <p>Each {@code JsonWriter} may be used to write a single JSON stream.
* Instances of this class are not thread safe. Calls that would result in a
* malformed JSON string will fail with an {@link IllegalStateException}.
