<p>JSON-GLib provides API for serializing and deserializing <span class="type">GObject</span>
instances to and from JSON data streams.</p>
<p>Simple <span class="type">GObject</span> classes can be (de)serialized into JSON objects, if the
properties have compatible types with the native JSON types (integers,
booleans, strings, string vectors). If the class to be (de)serialized has
complex data types for properties (like boxed types or other objects)
then the class should implement the provided <a class="link" href="json-glib-Serializable-Interface.html#JsonSerializable"><span class="type">JsonSerializable</span></a> interface
and its virtual functions.</p>
