Class `istreambuf_iterator<charT,traits>::proxy` is for exposition only.
|
| 18 |
-
An implementation is permitted to provide equivalent functionality
|
| 19 |
-
without providing a class with this name. Class
|
| 20 |
-
`istreambuf_iterator<charT, traits>::proxy` provides a temporary
|
| 21 |
-
placeholder as the return value of the post-increment operator
|
| 22 |
-
(`operator++`). It keeps the character pointed to by the previous value
|
| 23 |
-
of the iterator for some possible future access to get the character.
