$world->hookenabled
$world->hookenabled function: checks whether a HOOK is ENABLED
$result = $world->hookenabled( |
event
, |
name
) ; |
$result = $world->hookenabled( |
event
, |
number
) ; |
This function checks whether the specified hook exists and whether it is enabled.
The first argument is the name of the event. For the second, you
can pass either a hook number or name. If the hook does not exist,
this function returns undef
, so you can distinguish
the case of a non-existant hook from a disabled one.
If the hook exists, then the function returns 0 or 1 depending on whether it is enabled or not. If you pass a name, and there are several hooks with the same name, it returns a list with one value for each hook with that name, and each value is 0 or 1 depending on the state of the hook.
