60 \brief The QJsonArray class encapsulates a JSON array.-
61-
62 A JSON array is a list of values. The list can be manipulated by inserting and-
63 removing QJsonValue's from the array.-
64-
65 A QJsonArray can be converted to and from a QVariantList. You can query the-
66 number of entries with size(), insert(), and removeAt() entries from it-
67 and iterate over its content using the standard C++ iterator pattern.-
68-
69 QJsonArray is an implicitly shared class and shares the data with the document-
70 it has been created from as long as it is not being modified.-
71-
72 You can convert the array to and from text based JSON through QJsonDocument.-

711 \brief The QJsonArray::iterator class provides an STL-style non-const iterator for QJsonArray.-
712-
713 QJsonArray::iterator allows you to iterate over a QJsonArray-
714 and to modify the array item associated with the-
715 iterator. If you want to iterate over a const QJsonArray, use-
716 QJsonArray::const_iterator instead. It is generally a good practice to-
717 use QJsonArray::const_iterator on a non-const QJsonArray as well, unless-
718 you need to change the QJsonArray through the iterator. Const-
719 iterators are slightly faster and improves code readability.-
720-
721 The default QJsonArray::iterator constructor creates an uninitialized-
722 iterator. You must initialize it using a QJsonArray function like-
723 QJsonArray::begin(), QJsonArray::end(), or QJsonArray::insert() before you can-
724 start iterating.-
725-
726 Most QJsonArray functions accept an integer index rather than an-
727 iterator. For that reason, iterators are rarely useful in-
728 connection with QJsonArray. One place where STL-style iterators do-
729 make sense is as arguments to \l{generic algorithms}.-
730-
731 Multiple iterators can be used on the same array. However, be-
732 aware that any non-const function call performed on the QJsonArray-
733 will render all existing iterators undefined.-

945 \inmodule QtCore-
946 \brief The QJsonArray::const_iterator class provides an STL-style const iterator for QJsonArray.-
947-
948 QJsonArray::const_iterator allows you to iterate over a-
949 QJsonArray. If you want to modify the QJsonArray as-
950 you iterate over it, use QJsonArray::iterator instead. It is generally a-
951 good practice to use QJsonArray::const_iterator on a non-const QJsonArray-
952 as well, unless you need to change the QJsonArray through the-
953 iterator. Const iterators are slightly faster and improves-
954 code readability.-
955-
956 The default QJsonArray::const_iterator constructor creates an-
957 uninitialized iterator. You must initialize it using a QJsonArray-
958 function like QJsonArray::constBegin(), QJsonArray::constEnd(), or-
959 QJsonArray::insert() before you can start iterating.-
960-
961 Most QJsonArray functions accept an integer index rather than an-
962 iterator. For that reason, iterators are rarely useful in-
963 connection with QJsonArray. One place where STL-style iterators do-
964 make sense is as arguments to \l{generic algorithms}.-
965-
966 Multiple iterators can be used on the same array. However, be-
967 aware that any non-const function call performed on the QJsonArray-
968 will render all existing iterators undefined.-
