The code here and in JsonUtils.h is adapted from the "json-cpp" project, developed by Baptiste Lepilleur and put in the publi domain. Since the json-cpp project is relatively compact, and has not been updated in 3 years, we decided to simply incorporate it here instead of introducing another dependency.

Function Documentation

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

Output using the StyledStreamWriter.

See also:

Json::operator>>()

Definition at line 3511 of file JsonUtils.cpp.

{
   Json::StyledStreamWriter writer;
   writer.write(sout, root);
   return sout;
}

Here is the call graph for this function:

std::istream& operator>>	(	std::istream &	,
		Value &
	)

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.

{
    Json::Reader reader;
    bool ok = reader.parse(sin, root, true);
    //JSON_ASSERT( ok );
    if (!ok) throw std::runtime_error(reader.getFormatedErrorMessages());
    return sin;
}
