2900 | This is a variation of a method callback - leaving out the method to call |
|
|
2901 | will default the method to C<operator ()>, which makes it possible to use |
|
|
2902 | functor objects without having to manually specify the C<operator ()> all |

|
2903 | the time. Incidentally, you can then also leave out the template argument |
|
|
2904 | list. |

2905 | |
|
|
2906 | The C<operator ()> method prototype must be C<void operator ()(watcher &w, |
