31 Koha::Holds - Koha Hold object set class
41 returns a set of holds that are waiting from an existing set

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