protected function WorkflowTransitionBlock::blockAccess in Workflow 8

Indicates whether the block should be shown.

Blocks with specific access checking should override this method rather than access(), in order to avoid repeating the handling of the $return_as_object argument.

Parameters

\Drupal\Core\Session\AccountInterface $account: The user session for which to check access.

Return value

\Drupal\Core\Access\AccessResult The access result.

Overrides BlockPluginTrait::blockAccess
