+ * @brief   Adapter implementation for the QtJson parser library.

+ * Include this file in your program to enable support for QtJson.

+ *  - QtJsonArray
+ *  - QtJsonArrayValueIterator
+ *  - QtJsonFrozenValue
+ *  - QtJsonObject
+ *  - QtJsonObjectMember
+ *  - QtJsonObjectMemberIterator

+ * class declarations and definitions may be a bit confusing. The best place to
+ * start is QtJsonAdapter. This class definition is actually very small,
+ * since most of the functionality is inherited from the BasicAdapter class.
+ * Most of the classes in this file are provided as template arguments to the
+ * inherited BasicAdapter class.
