=head3 forced_hold_level
|
|
|
|
If a patron has multiple holds for a single record,
|
|
those holds must be either all record level holds,
|
|
or they must all be item level holds.
|
|
|
|
This method should be used with Hold sets where all
|
|
Hold objects share the same patron and record.
|
|
|
|
This method will return 'item' if the patron has
|
|
at least one item level hold. It will return 'record'
|
|
if the patron has holds but none are item level,
|
|
Finally, if the patron has no holds, it will return
|
|
undef which indicates the patron may select either
|
|
record or item level holds, barring any other rules
|
|
that would prevent one or the other.
