state() public méthode

Use Key::STATE_NAMED and Key::STATE_INCOMPLETE to check value. Example: An incomplete key does not have an ID on its last path element. $key = $datastore->key('parent', 1234) ->pathElement('child'); if ($key->state() === Key::STATE_INCOMPLETE) { echo 'Key is incomplete!'; } A named key has a kind and an identifier on each path element. $key = $datastore->key('parent', 1234) ->pathElement('child', 4321); if ($key->state() === Key::STATE_NAMED) { echo 'Key is named!'; }

  * Example:
