The class template `basic_stringstream<charT, traits>` supports reading
|
| 68 |
+
and writing from objects of class
|
| 69 |
+
`basic_string<charT, traits, Allocator>`. It uses a
|
| 70 |
+
`basic_stringbuf<charT, traits, Allocator>` object to control the
|
| 71 |
+
associated sequence. For the sake of exposition, the maintained data is
|
| 72 |
+
presented here as
|
| 73 |
+
|
| 74 |
+
- `sb`, the `stringbuf` object.
