@events =   $session->getExplainedBy($object, $event[, $onehop ]);

The getExplainedBy() function is the inverse of the getExplains() function.

It returns those problems (or events) which the MODEL developer has listed as explaining this event.

The $onehop parameter is optional:

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

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

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

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