public function License::preSave in Commerce License 8.2

Acts on an entity before the presave hook is invoked.

Used before the entity is saved and before invoking the presave hook. Note that in case of translatable content entities this callback is only fired on their current translation. It is up to the developer to iterate over all translations if needed. This is different from its counterpart in the Field API, FieldItemListInterface::preSave(), which is fired on all field translations automatically. @todo Adjust existing implementations and the documentation according to https://www.drupal.org/node/2577609 to have a consistent API.

Parameters

\Drupal\Core\Entity\EntityStorageInterface $storage: The entity storage object.

Throws

\Exception When there is a problem that should prevent saving the entity.

Overrides ContentEntityBase::preSave

File

src/Entity/License.php, line 84

Class

License: Defines the License entity.

Namespace

Drupal\commerce_license\Entity

Code

  parent::preSave($storage);

  // Act when the license state changes, or the license is new.
  // (Note that $this->original is not set on new entities.)

    // expiration timestamps, and notify the license type plugin. We act on
    // preSave() rather than postSave() so that the license plugin can set
    // values on the license. HOWEVER, this means that if something acts in
    // hook_entity_presave() to prevent saving, by throwing an exception, the
    // license entity will be unsaved, but the license plugin will have
    // granted the license, leaving it in an incorrect state.

    // revert the grant if the save is cancelled.
