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.

Default constructor starts with an empty string buffer.
| mode | Whether the buffer can read, or write, or both. |
ios_base::out is automatically included in mode.
Initializes sb using mode|out, and passes &sb to the base class initializer. Does not allocate any buffer.

Starts with an existing string buffer.
| str | A string to copy as a starting buffer. | |
| mode | Whether the buffer can read, or write, or both. |
ios_base::out is automatically included in mode.
Initializes sb using str and mode|out, and passes &sb to the base class initializer.
