=head1 DESCRIPTION |
| 20 |
|
|
|
| 21 |
|
|
This module is just a small helper module for the connection |
| 22 |
|
|
and client classes. |
| 23 |
|
|
|
| 24 |
|
|
You may only derive from this package. |

|
=head2 reg_cb ($eventname1, $cb1, [$eventname2, $cb2, ...]) |
| 27 |
|
|
|
| 28 |
|
|
This method registers a callback C<$cb1> for the event with the |
| 29 |
|
|
name C<$eventname1>. You can also pass multiple of these eventname => callback |
| 30 |
|
|
pairs. |
| 31 |
|
|
|
| 32 |
|
|
To see a documentation of emitted events please take a look at the EVENTS section |
