+/// @class StructuredData StructuredData.h "lldb/Core/StructuredData.h"
+/// @brief A class which can hold structured data
+///
+/// The StructuredData class is designed to hold the data from a JSON
+/// or plist style file -- a serialized data structure with dictionaries
+/// (maps, hashes), arrays, and concrete values like integers, floating
+/// point numbers, strings, booleans.
+///
+/// StructuredData does not presuppose any knowledge of the schema for
+/// the data it is holding; it can parse JSON data, for instance, and
+/// other parts of lldb can iterate through the parsed data set to find
+/// keys and values that may be present.
