access to event handlers within modules?

[revolution]

i'm interested in creating plesk modules. i've looked through the plesk sdk and module documentation and can't find the answer to this, but i'm assuming it's possible because i imagine software such as the 4psa software does this.

does anybody know if there's a way to "register" event handlers with one's module that don't show in the event handlers area of the server administration page? things could go very wrong if an admin removed or modified an event handler that the module had put there. the idea is the admin shouldn't be able to see the event handlers there. they should be forced to either remove the entire module or not mess the parts of it, such as the event handlers.

or maybe there's some other method within modules? some form of hooks one can use?

thanks.
