Detailed Description

template<typename BasicJsonType>
class detail::json_sax_dom_parser< BasicJsonType >

SAX implementation to create a JSON value from SAX events.

This class implements the json_sax interface and processes the SAX events to create a JSON value which makes it basically a DOM parser. The structure or hierarchy of the JSON value is managed by the stack ref_stack which contains a pointer to the respective array or object for each recursion depth.

After successful parsing, the value that is passed by reference to the constructor contains the parsed value.

Template Parameters

BasicJsonType the JSON type
