# FIXME: This method is effectively useless the way the current add_item method is written. Ideally, the items should be added to the object
# and then the save method called. This does not work well in practice due to the inability to pass objects across cgi script calls.
# I'm leaving it here because it should be here and for consistency's sake and once memcached support is fully implemented this should be as well. -cnighswonger
#
#=head2 $batch->save()

# Invoking the I<save> method attempts to insert the batch into the database. The method returns
# the new record batch_id upon success and -1 upon failure (This avoids conflicting with a record
# batch_id of 1). Errors are logged to the Apache log.

# my $exitstat = $batch->save(); # to save the record behind the $batch object
#

=head1 NAME
C4::Labels::Batch - A class for creating and manipulating batch objects in Koha
=head1 ABSTRACT
This module provides methods for creating, and otherwise manipulating batch objects used by Koha to create and export labels.
=head1 METHODS
=head2 new()
Invoking the I<new> method constructs a new batch object with no items. It is possible to pre-populate the batch with items and a branch code by passing them
as in the second example below.
B<NOTE:> The items list must be an arrayref pointing to an array of hashes containing a key/data pair after this fashion: {item_number => item_number}. The order of
the array elements determines the order of the items in the batch.
example:
C<my $batch = C4::Labels::Batch->new(); # Creates and returns a new batch object>
C<my $batch = C4::Labels::Batch->new(items => $arrayref, branch_code => branch_code) # Creates and returns a new batch object containing the items passed in
with the branch code passed in.>
B<NOTE:> This batch is I<not> written to the database until C<$batch->save()> is invoked. You have been warned!
=head2 $batch->add_item(item_number => $item_number, branch_code => $branch_code)
Invoking the I<add_item> method will add the supplied item to the batch object.
example:
$batch->add_item(item_number => $item_number, branch_code => $branch_code);
=head2 $batch->get_attr($attribute)
Invoking the I<get_attr> method will return the requested attribute.
example:
my @items = $batch->get_attr('items');
=head2 $batch->remove_item($item_number)
Invoking the I<remove_item> method will remove the supplied item number from the batch object.
example:
$batch->remove_item($item_number);
=head2 C4::Labels::Batch->retrieve(batch_id => $batch_id)
Invoking the I<retrieve> method constructs a new batch object containing the current values for batch_id. The method returns a new object upon success and 1 upon failure.
Errors are logged to the Apache log.
examples:
my $batch = C4::Labels::Batch->retrieve(batch_id => 1); # Retrieves batch 1 and returns an object containing the record
=head2 delete()
Invoking the delete method attempts to delete the template from the database. The method returns -1 upon failure. Errors are logged to the Apache log.
NOTE: This method may also be called as a function and passed a key/value pair simply deleteing that batch from the database. See the example below.
examples:
my $exitstat = $batch->delete(); # to delete the record behind the $batch object
my $exitstat = C4::Labels::Batch->delete(batch_id => 1); # to delete batch 1
=head2 remove_duplicates()
Invoking the remove_duplicates method attempts to remove duplicate items in the batch from the database. The method returns the count of duplicate records removed upon
success and -1 upon failure. Errors are logged to the Apache log.
NOTE: This method may also be called as a function and passed a key/value pair removing duplicates in the batch passed in. See the example below.
examples:
my $remove_count = $batch->remove_duplicates(); # to remove duplicates the record behind the $batch object
my $remove_count = C4::Labels::Batch->remove_duplicates(batch_id => 1); # to remove duplicates in batch 1
