1 node.module node_access_acquire_grants(Node $node, $delete = TRUE)

Gets the list of node access grants and writes them to the database.

This function is called when a node is saved, and can also be called by modules if something other than a node save causes node access permissions to change. It collects all node access grants for the node from hook_node_access_records() implementations, allows these grants to be altered via hook_node_access_records_alter() implementations, and saves the collected and altered grants to the database.

Parameters

Node $node: The $node to acquire grants for.

$delete: (optional) Whether to delete existing node access records before inserting new ones. Defaults to TRUE.
