erics, August 4th, 2019 I wanted to call a sub-routine based on a variable in Perl, like this:
|
1 2 |
our $role = 'master'; &$role; |
but it failed because of use strict:
|
1 |
Can't use string ("master") as a subroutine ref while "strict refs" in use at /opt/continuent/tungsten/tools/tungsten_find_orphaned line 213. |
To enable using a variable as a reference, simply specify that to Perl:
|
1 2 |
use strict no strict "refs"; |

Inside class “yourClassB” getting the call from “yourClassA”:

class yourClassB { public function setClass($object = NULL) { if(is_object($object) and $object instanceof yourClassA) { $this->RefToClassA = $object; $this->yourVar = $RefToClassA->otherVar; // etc, etc, etc... } } } |
