 application_data_link::get_links_to -object_id object_id \
    [ -from_type from_type ] [ -relation_tag relation_tag ]

Defined in packages/acs-tcl/tcl/application-data-link-procs.tcl

Get a list of objects that are linked to an object, possible using the relation_tag. If from_type is a subtype of content_revision, we lookup content_items that have that content_type

Switches:

-object_id (required)

object_id two, get objects linked to this object

-from_type (optional)

object_type of the objects to get links from

-relation_tag (optional)
