Serializable.defaultSerializeProperty

Calls the default implementation of the vfuncJson.Serializable.serialize_property virtual function.

This function can be used inside a custom implementation of the serialize_property() virtual function in lieu of calling the default implementation through [gobject.global.typeDefaultInterfacePeek]:

JsonSerializable *iface;
JsonNode *node;

iface = g_type_default_interface_peek (JSON_TYPE_SERIALIZABLE);
node = iface->serialize_property (serializable, property_name,
                                  value,
                                  pspec);

This function will return NULL if the property could not be serialized.
