xo::db::CrFolder proc fetch_object (public)

 xo::db::CrFolder fetch_object -item_id item_id  \
    [ -revision_id revision_id ] -object object  \
    [ -initialize on|off ]

Defined in packages/xotcl-core/tcl/cr-procs.tcl

We overwrite the default fetch_object method here. We join acs_objects, cr_items and cr_folders and fetch all attributes. The revision_id is completely ignored.

Switches:

-item_id

(required)

-revision_id

(defaults to "0") (optional)

-object

(required)

-initialize

(boolean) (defaults to "true") (optional)
