PHP NodeInterface::getOwnerId方法代碼示例

/**
 * Set permissions for a node to be written to the database.
 *
 * When a node is saved, a module implementing hook_node_access_records() will
 * be asked if it is interested in the access permissions for a node. If it is
 * interested, it must respond with an array of permissions arrays for that
 * node.
 *
 * Node access grants apply regardless of the published or unpublished status
 * of the node. Implementations must make sure not to grant access to
 * unpublished nodes if they don't want to change the standard access control
 * behavior. Your module may need to create a separate access realm to handle
 * access to unpublished nodes.
 *
 * Note that the grant values in the return value from your hook must be
 * integers and not boolean TRUE and FALSE.
 *
 * Each permissions item in the array is an array with the following elements:
 * - 'realm': The name of a realm that the module has defined in
 *   hook_node_grants().
 * - 'gid': A 'grant ID' from hook_node_grants().
 * - 'grant_view': If set to 1 a user that has been identified as a member
 *   of this gid within this realm can view this node. This should usually be
 *   set to $node->isPublished(). Failure to do so may expose unpublished content
 *   to some users.
 * - 'grant_update': If set to 1 a user that has been identified as a member
 *   of this gid within this realm can edit this node.
 * - 'grant_delete': If set to 1 a user that has been identified as a member
 *   of this gid within this realm can delete this node.
 * - langcode: (optional) The language code of a specific translation of the
 *   node, if any. Modules may add this key to grant different access to
 *   different translations of a node, such that (e.g.) a particular group is
 *   granted access to edit the Catalan version of the node, but not the
 *   Hungarian version. If no value is provided, the langcode is set
 *   automatically from the $node parameter and the node's original language (if
 *   specified) is used as a fallback. Only specify multiple grant records with
 *   different languages for a node if the site has those languages configured.
 *
 * A "deny all" grant may be used to deny all access to a particular node or
 * node translation:
 * @code
 * $grants[] = array(
 *   'realm' => 'all',
 *   'gid' => 0,
 *   'grant_view' => 0,
 *   'grant_update' => 0,
 *   'grant_delete' => 0,
 *   'langcode' => 'ca',
 * );
 * @endcode
 * Note that another module node access module could override this by granting
 * access to one or more nodes, since grants are additive. To enforce that
 * access is denied in a particular case, use hook_node_access_records_alter().
 * Also note that a deny all is not written to the database; denies are
 * implicit.
 *
 * @param \Drupal\node\NodeInterface $node
 *   The node that has just been saved.
 *
 * @return
 *   An array of grants as defined above.
 *
 * @see hook_node_access_records_alter()
 * @ingroup node_access
