FS::bill_batch - Object methods for bill_batch records
=head1 SYNOPSIS
use FS::bill_batch;
$open_batch = FS::bill_batch->get_open_batch;
my $pdf = $open_batch->print_pdf;
$error = $open_batch->close;
=head1 DESCRIPTION
An FS::bill_batch object represents a batch of invoices. FS::bill_batch
inherits from FS::Record. The following fields are currently supported:
=over 4
=item batchnum - primary key
=item status - either 'O' (open) or 'R' (resolved/closed).
=item pdf - blob field for temporarily storing the invoice as a PDF.
=back
=head1 METHODS
=over 4
=item print_pdf
Typeset the entire batch as a PDF file. Returns the PDF as a string.
=cut

my $self = shift;
my $job = shift;

$num++;
my $error = $job->update_statustext(int(100 * $num/scalar(@invoices)));
die $error if $error;
}
}
return $pdf_out->toPDF;
}
=item close
Set the status of the batch to 'R' (resolved).
=cut

=head1 CLASS METHODS
=item get_open_batch
Returns the currently open batch. There should only be one at a time.
