Starts with an existing string buffer. | |
~basic_ostringstream () | |

This class supports writing to objects of type std::basic_string, using the inherited functions from std::basic_ostream. To control the associated sequence, an instance of std::basic_stringbuf is used, which this page refers to as sb
.

These are standard types. They permit a standardized way of referring to names of (or names dependant on) the template parameters, which are specific to the implementation.
