function domain_node_access_records in Domain Access 7.2

Same name and namespace in other branches

1. 5 domain.module \domain_node_access_records()
2. 6.2 domain.module \domain_node_access_records()
3. 7.3 domain.module \domain_node_access_records()

Implements hook_node_access_records()

Set permissions for a node to be written to the database. By design if no options are selected, the node is assigned to the main site.

Developers: if you modify these grants with hook_node_access_records_alter(), you may also need to call _domain_store_grants() to update the {domain_access} table properly.
