89 | =head2 _AddLinksOnCreate | |
90 | ||
91 | Calls _AddLink (usually L<RT::Record/_AddLink>) for all valid link types and | |
92 | aliases found in the hash. Refer to L<RT::Link/%TYPEMAP> for details of link | |
93 | types. Key values may be a single URI or an arrayref of URIs. | |
94 | ||
95 | Takes two hashrefs. The first is the argument hash provided to the consuming | |
96 | class's Create method. The second is optional and contains extra arguments to | |
97 | pass to _AddLink. | |
98 | ||
99 | By default records a transaction on the link's destination object (if any), but | |
100 | not on the origin object. | |
101 | ||
102 | Returns an array of localized error messages, if any. | |
