[Jsoncpp-cvs] about valueToString() interface

[<jso...@li...>]

Hi, ALL

     I have a doubt that the function std::string valueToString( double
value) for example , return std::string that will call copy construct
function.

.         As we all know , this is Low performance. If we serialize a large
Json Value recursively, that will be expensive. So why don't we change the
interface to

.         bool valueToString( double value, std::string& ret), return the
value by reference. 

Thanks all.

.
