Qt-based simple JSON reader inspired by the one from Zoolib.
static JsonListIterator initListIterator(QIODevice *in)
Create a JsonListIterator from the given input device.
static QVariant parse(QIODevice *input)
Parse the given input stream.
static void write(const QVariant &jsonObject, QIODevice *output, int indentLevel=0)
Serialize the passed QVariant as JSON into the output QIODevice.
Qt-style iterator over a JSON array.
bool hasNext() const
Returns true if the next non-whitespace character is not a ']' character.
QVariant next()
Reads and parses the next object from input.
JsonListIterator(QIODevice *input)
Sets up JsonListIterator to read an array.
