getExplains

@events =  $session->getExplains($object, $eventname[, $onehop ]);

MODEL developers can add information to a problem in order to emphasize events that occur because of a problem. The getExplains() function returns a list of these events.

The $onehop parameter is optional:

• If it is omitted or passed as FALSE, the full list of problems that explain $eventname, whether directly or indirectly, is returned.

• If it is passed as TRUE, only those problems that directly list eventname among the events they explain are returned.

  The function returns an array of array references with the format:

   [
    [ <classname::instancename>,<problemname> ],
    [ <classname::instancename>,<problemname> ],
    ...
   ]
