public NodeGrantDatabaseStorage::write(NodeInterface $node, array $grants, $realm = NULL, $delete = TRUE)
Writes a list of grants to the database, deleting previously saved ones.
If a realm is provided, it will only delete grants from that realm, but it will always delete a grant from the 'all' realm. Modules that use node access can use this method when doing mass updates due to widespread permission changes.
Note: Don't call this method directly from a contributed module. Call \Drupal\node\NodeAccessControlHandlerInterface::acquireGrants() instead.
Parameters
\Drupal\node\NodeInterface $node: The node whose grants are being written.
array $grants: A list of grants to write. Each grant is an array that must contain the following keys: realm, gid, grant_view, grant_update, grant_delete. The realm is specified by a particular module; the gid is as well, and is a module-defined id to define grant privileges. each grant_* field is a boolean value.
string $realm: (optional) If provided, read/write grants for that realm only. Defaults to NULL.
bool $delete: (optional) If false, does not delete records. This is only for optimization purposes, and assumes the caller has already performed a mass delete of some form. Defaults to TRUE.
