Data Types

JsonElement

Stores the structure obtained after JSON deserialization and provides an interface for retrieving node values of basic data types by key.

class JsonElement : public Object {
    shared<kacc_json::Document> doc{nullptr};
    kacc_json::Node *node{nullptr};
};

GsonObject

Inherits from JsonElement and provides interfaces for obtaining child nodes of complex data types.

class GsonObject : public JsonElement {
public:
    using JsonElement::JsonElement;
    GsonObject *getAsJsonObject(const std::string &key);
    JsonArray *getAsJsonArray(std::string_view key) const;
};

JsonArray

Inherits from JsonElement and provides the Array interface adapted to the Java basic library.

class JsonArray final : public JsonElement {
public:
    class JsonArrayIterator final : public Iterator {
        using jsonArrayIterator = std::list<JsonElement *>::iterator;
        jsonArrayIterator current_;
        jsonArrayIterator end_;
    public:
        JsonArrayIterator(const jsonArrayIterator begin, const jsonArrayIterator end);
        bool hasNext() override;
        Object *next() override;
    };

    void addLast(JsonElement *a);
    std::list<JsonElement *> list;
    Iterator *iterator();
    ~JsonArray() override;
};

JsonParser

Provides the deserialization interface.

class JsonParser final : public Object {
public:
    static JsonElement *parseString(String *str);
};

Gson

Provides the toJson and fromJson interfaces.

class Gson : public Object {
public:
    static String *toJson(JsonElement *jsonElement);
    static String *toJson(Map *map);
    static String *toJson(Object *obj);
    static Object *fromJson(std::string str);
    static Object *fromJson(String *str);
private:
    static kacc_json::Node map2JsonNode(Map &map, Allocator &allo);
    static kacc_json::Node list2JsonNode(List &list, Allocator &allo);
};
