Detailed Description

JSON (JavaScript Object Notation).

Function Documentation

std::ostream& Json::operator<<	(	std::ostream &	sout,
		const Value &	root
	)

Output using the StyledStreamWriter.

Json::operator>>()

std::istream& Json::operator>>	(	std::istream &	sin,
		Value &	root
	)

Read from 'sin' into 'root'.

Always keep comments from the input JSON.

This can be used to read a file into a particular sub-object. For example:

Json::Value root;
cin >> root["dir"]["file"];
cout << root;

Result:

{
"dir": {
    "file": {
    // The input stream JSON would be nested here.
    }
}
}

Exceptions

std::exception

on parse error.
