Struct
JsonObject
Description [src]
struct JsonObject {
/* No available fields */
}
JsonObject is the representation of the object type inside JSON.
A JsonObject contains JsonNode “members”, which may contain
fundamental types, arrays or other objects; each member of an object is
accessed using a unique string, or “name”.
Since objects can be arbitrarily big, copying them can be expensive; for
this reason they are reference counted. You can control the lifetime of
a JsonObject using json_object_ref() and json_object_unref().
To add or overwrite a member with a given name, use json_object_set_member().
To extract a member with a given name, use json_object_get_member().
To retrieve the list of members, use json_object_get_members().
To retrieve the size of the object (that is, the number of members it has), use json_object_get_size().
Constructors
