246 | In addition to specifying a boolean, you can specify a code reference that |
|
|
247 | is called for every code execution attempt - the execution request is |
|
|
248 | granted iff the callback returns a true value. |
|
|
249 | |
|
|
250 | Most of the time the callback should look only at |
|
|
251 | C<$AnyEvent::MP::Kernel::SRCNODE> to make a decision, and not at the |
|
|
252 | actual message (which can be about anything, and is mostly provided for |
|
|
253 | diagnostic purposes). |
