Description:

JSON-GLib is a library for reading and parsing JSON using GLib and GObject data types and API.

Content:

Namespaces:

• Json

Interfaces:

• Serializable - `JsonSerializable` is an interface for controlling the serialization and deserialization of `GObject` classes.

Classes:

• Array - `JsonArray` is the representation of the array type inside JSON.
• Builder - `JsonBuilder` provides an object for generating a JSON tree.
• Generator - `JsonGenerator` provides an object for generating a JSON data stream from a tree of [struct@Json.
• Node - A generic container of JSON data types.
• Object - `JsonObject` is the representation of the object type inside JSON.
• Parser - `JsonParser` provides an object for parsing a JSON data stream, either inside a file or inside a static buffer.
• Path - `JsonPath` is a simple class implementing the JSONPath syntax for extracting data out of a JSON tree.
• Reader - `JsonReader` provides a simple, cursor-based API for parsing a JSON DOM.

Structs:

• ObjectIter - An iterator object used to iterate over the members of a JSON object.

Enums:

• NodeType - Indicates the content of a node.

Error domains:

• ParserError - Error codes for `JSON_PARSER_ERROR`.
• PathError - Error codes for `JSON_PATH_ERROR`.
• ReaderError - Error codes for `JSON_READER_ERROR`.

Constants:

• public const int MAJOR_VERSION
  Json major version component (e.
• public const int MICRO_VERSION
  Json micro version component (e.
• public const int MINOR_VERSION
  Json minor version component (e.
• public const int VERSION_HEX
• public const string VERSION_S
  The version of JSON-GLib, encoded as a string, useful for printing and concatenation.

Delegates:

• public delegate void ArrayForeach (Array array, uint index_, Node element_node)
  The function to be passed to [method@Json.
• public delegate void* BoxedDeserializeFunc (Node node)
  Deserializes the contents of the passed `JsonNode` into a `GBoxed`, for instance:
• public delegate Node BoxedSerializeFunc (void* boxed)
  Serializes the passed `GBoxed` and stores it inside a `JsonNode`, for instance:
• public delegate void ObjectForeach (Object object, string member_name, Node member_node)
  The function to be passed to [method@Json.

Methods:

• public bool boxed_can_deserialize (Type gboxed_type, NodeType node_type)
  Checks whether it is possible to deserialize a `GBoxed` of type `gboxed_type` from a [struct@Json.
• public bool boxed_can_serialize (Type gboxed_type, out NodeType node_type)
  Checks whether it is possible to serialize a `GBoxed` of type `gboxed_type` into a [struct@Json.
• public void* boxed_deserialize (Type gboxed_type, Node node)
  Deserializes the given [struct@Json.
• public void boxed_register_deserialize_func (Type gboxed_type, NodeType node_type, BoxedDeserializeFunc deserialize_func)
  Registers a deserialization function for a `GBoxed` of type `gboxed_type` from a [struct@Json.
• public void boxed_register_serialize_func (Type gboxed_type, NodeType node_type, BoxedSerializeFunc serialize_func)
  Registers a serialization function for a `GBoxed` of type `gboxed_type` to a [struct@Json.
• public Node? boxed_serialize (Type gboxed_type, void* boxed)
  Serializes a pointer to a `GBoxed` of the given type into a [struct@Json.
• public Object? construct_gobject (Type gtype, string data, size_t length) throws Error
  Deserializes a JSON data stream and creates an instance of the given type.
• public Node? from_string (string str) throws Error
  Parses the given string and returns the corresponding JSON tree.
• public Object gobject_deserialize (Type gtype, Node node)
  Creates a new `GObject` instance of the given type, and constructs it using the members of the object in the given node.
• public Object? gobject_from_data (Type gtype, string data, ssize_t length = -1) throws Error
  Deserializes a JSON data stream and creates an instance of the given type.
• public Node gobject_serialize (Object gobject)
  Creates a JSON tree representing the passed object instance.
• public string gobject_to_data (Object gobject, out size_t length)
  Serializes a `GObject` instance into a JSON data stream, iterating recursively over each property.
• public Variant? gvariant_deserialize (Node json_node, string? signature) throws Error
  Converts a JSON data structure to a `GVariant`.
• public Variant? gvariant_deserialize_data (string json, ssize_t length, string? signature) throws Error
  Converts a JSON string to a `GVariant` value.
• public Node gvariant_serialize (Variant variant)
  Converts `variant` to a JSON tree.
• public string gvariant_serialize_data (Variant variant, out size_t length)
  Converts variant to its JSON encoded string representation.
• public Quark parser_error_quark ()
• public Quark path_error_quark ()
• public Quark reader_error_quark ()
• public string serialize_gobject (Object gobject, out size_t length)
  Serializes a `GObject` instance into a JSON data stream.
• public int string_compare (string a, string b)
  Check whether a and b are equal UTF-8 JSON strings and return an ordering over them in `strcmp()` style.
• public bool string_equal (string a, string b)
  Check whether a and b are equal UTF-8 JSON strings.
• public uint string_hash (string key)
  Calculate a hash value for the given key (a UTF-8 JSON string ).
• public string to_string (Node node, bool pretty)
  Generates a stringified JSON representation of the contents of the given `node`.
