public function TransformerExtender::__construct in Facebook Instant Articles 7.2

Transformer constructor.

Adds Drupal hook to allow transformer rules to be added by other modules. We invoke the hook in a constructor - as opposed to inside transform() or a new invokeRules() method - because of the way Transformer is normally used.

Note the parent class does not have a constructor, so we do not call

parent::__construct();

.
