protected function ControllerBase::state in Drupal 9

Same name and namespace in other branches

1. 8 core/lib/Drupal/Core/Controller/ControllerBase.php \Drupal\Core\Controller\ControllerBase::state()
2. 10 core/lib/Drupal/Core/Controller/ControllerBase.php \Drupal\Core\Controller\ControllerBase::state()

Returns the state storage service.

Use this to store machine-generated data, local to a specific environment that does not need deploying and does not need human editing; for example, the last time cron was run. Data which needs to be edited by humans and needs to be the same across development, production, etc. environments (for example, the system maintenance message) should use config() instead.

Return value
