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

54 returns a set of holds that are unfilled from an existing set
61 return $self->search( { found => undef } );
64 =head3 forced_hold_level
66 If a patron has multiple holds for a single record,
67 those holds must be either all record level holds,
68 or they must all be item level holds.
70 This method should be used with Hold sets where all
71 Hold objects share the same patron and record.
73 This method will return 'item' if the patron has
74 at least one item level hold. It will return 'record'
75 if the patron has holds but none are item level,
76 Finally, if the patron has no holds, it will return
77 undef which indicates the patron may select either
78 record or item level holds, barring any other rules
79 that would prevent one or the other.
