193 =head3 can_be_transferred
195 $item->can_be_transferred({ to => $to_library, from => $from_library })
196 Checks if an item can be transferred to given library.
198 This feature is controlled by two system preferences:
199 UseBranchTransferLimits to enable / disable the feature
200 BranchTransferLimitsType to use either an itemnumber or ccode as an identifier
201 for setting the limitations
203 Takes HASHref that can have the following parameters:
204 MANDATORY PARAMETERS:
207 $from : Koha::Library # if not given, item holdingbranch
208 # will be used instead
210 Returns 1 if item can be transferred to $to_library, otherwise 0.
212 To find out whether at least one item of a Koha::Biblio can be transferred, please
213 see Koha::Biblio->can_be_transferred() instead of using this method for
214 multiple items of the same biblio.
