Assign ostream to a datatype string in c++. I have a below method that I can understand by name is converting the output in a pretty format to display. But I don't understand what this code is doing and what is its return type. How can I assign this return type to a string datatype which I want to access from javascript. javascript

class Log { private: std::ostream* os; bool dynamic; public: Log(std::ostream& os = std::cout): os(&os), dynamic(false) { } Log(std::string filename) : dynamic(true)

Stream class to operate on strings. Objects of this class use a string buffer that contains a sequence of characters. This sequence of characters can be accessed directly as a string object, using member str. Characters can be inserted and/or extracted from the stream using any operation allowed on both input and output streams. In this article. Output streams use the insertion (<<) operator for standard types.You can also overload the << operator for your own classes..

Ostream to string

Let's take a look at a piece of code Apr 28, 2017 It is currently not possible to write a std::string_view to an std::ostream. Working around this requires an expensive conversion to an std::string, Jul 29, 2017 Summary: We have a lot of code to convert to strings that uses Using the << operator with a stringstream returns an ostream, which doesn't Is there any standard way of converting ros::serialization::OStream to any standard format like std::string or std::stringstream? std::string Movie::name is private · character constant too long for its type no match for call to (std::ostream {aka std::basic_ostream}) (const char [12]) format string compilation; fmt/color.h: terminal color and text style; fmt/ostream.h : The fields are replaced with formatted arguments in the resulting string.
