|JsonListIterator (QIODevice *input)|

|Returns true if the next non-whitespace character is not a ']' character. |
Qt-style iterator over a JSON array.
An actual list is not kept in memory, so only forward iteration is supported and all methods, including the constructor, involve read() calls on the QIODevice. Because of this, do not modify the QIODevice between calls to JsonListIterator methods. Also, the toFront() method has a special function and reset() is provided for convenience. Only peekNext() is guaranteed not to modify the QIODevice.
Sets up JsonListIterator to read an array.
Swallows all whitespace up to a beginning '[' character. If '[' is not the first non-whitespace character encountered, reset() is called and an exception is thrown.
|bool JsonListIterator::hasNext||(||)|| const
Returns true if the next non-whitespace character is not a ']' character.
Reads and parses the next object from input.
Advances QIODevice to just after the object.
