Template Class json_sax_dom_parser

Class Documentation

template<typename BasicJsonType>
class json_sax_dom_parser

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
