site_node::update_cache (public)

 site_node::update_cache [ -sync_children ] -node_id node_id \
    [ -url url ] [ -object_id object_id ]

Defined in packages/acs-tcl/tcl/site-nodes-procs.tcl

Brings the in-memory copy of the site nodes hierarchy in sync with the database version. Only updates the given node and its children.

Switches:

-sync_children

(boolean) (optional)

-node_id

(required)

-url

(optional)

-object_id

(optional)

Partial Call Graph (max 5 caller/called nodes):
