=head3 can_be_transferred
|
|
|
|
$biblio->can_be_transferred({ to => $to_library, from => $from_library })
|
|
|
|
Checks if at least one item of a biblio can be transferred to given library.
|
|
|
|
This feature is controlled by two system preferences:
|
|
UseBranchTransferLimits to enable / disable the feature
|
|
BranchTransferLimitsType to use either an itemnumber or ccode as an identifier
|
|
for setting the limitations
|
|
|
|
Performance-wise, it is recommended to use this method for a biblio instead of
|
|
iterating each item of a biblio with Koha::Item->can_be_transferred().
|
|
|
|
Takes HASHref that can have the following parameters:
|
|
MANDATORY PARAMETERS:
|
|
$to : Koha::Library
|
|
OPTIONAL PARAMETERS:
|
|
$from : Koha::Library # if given, only items from that
|
|
# holdingbranch are considered
|
|
|
|
Returns 1 if at least one of the item of a biblio can be transferred
|
|
to $to_library, otherwise 0.
