Koha::Library - Koha Library Object class

=head1 API

=head2 Class methods

=head3 stockrotationstages

  my $stages = Koha::Library->stockrotationstages;

Returns the stockrotation stages associated with this Library.

=cut

=head3 outgoing_transfers

  my $outgoing_transfers = Koha::Library->outgoing_transfers;

Returns the outgoing item transfers associated with this Library.

=cut

sub outgoing_transfers {
    my ( $self ) = @_;
    my $rs = $self->_result->branchtransfers_frombranches;
    return Koha::Item::Transfers->_new_from_dbic( $rs );
}

=head3 inbound_transfers

  my $inbound_transfers = Koha::Library->inbound_transfers;

Returns the inbound item transfers associated with this Library.

=cut

sub inbound_transfers {
    my ( $self ) = @_;
    my $rs = $self->_result->branchtransfers_tobranches;
    return Koha::Item::Transfers->_new_from_dbic( $rs );
}

=head3 get_effective_marcorgcode

    my $marcorgcode = Koha::Libraries->find( $library_id )->get_effective_marcorgcode();

Returns the effective MARC organization code of the library. It falls back to the value
from the I<MARCOrgCode> syspref if undefined for the library.

=cut

=head3 smtp_server

    my $smtp_server = $library->smtp_server;
    $library->smtp_server({ smtp_server => $smtp_server });
    $library->smtp_server({ smtp_server => undef });

Accessor for getting and setting the library's SMTP server.

Returns the effective SMTP server configuration to be used on the library. The returned
value is always a I<Koha::SMTP::Server> object.

Setting it to undef will remove the link to a specific SMTP server and effectively
make the library use the default setting

=head3 from_email_address

  my $from_email = Koha::Library->from_email_address;

Returns the official 'from' email address for the branch.

It may well be a 'noreply' or other inaccessible local domain
address that is being used to satisfy spam protection filters.

=head3 inbound_email_address

  my $to_email = Koha::Library->inbound_email_address;

Returns an effective email address which should be accessible to librarians at the branch.

NOTE: This is the address to use for 'reply_to' or 'to' fields; It should not usually be
used as the 'from' address for emails as it may lead to mail being caught by spam filters.

for inter library loans communication.
