=head1 NAME

FS::cust_bill_pkg_void - Object methods for cust_bill_pkg_void records

=head1 SYNOPSIS

  use FS::cust_bill_pkg_void;

  $record = new FS::cust_bill_pkg_void \%hash;
  $record = new FS::cust_bill_pkg_void { 'column' => 'value' };

  $error = $record->insert;

  $error = $new_record->replace($old_record);

  $error = $record->delete;

  $error = $record->check;

=head1 METHODS

=over 4

=item new HASHREF

Creates a new record.  To add the record to the database, see L<"insert">.

Note that this stores the hash reference, not a distinct copy of the hash it
points to.  You can ask the object for a copy with the I<hash> method.

=item insert

Adds this record to the database.  If there is an error, returns the error,
otherwise returns false.

=item unvoid 

"Un-void"s this line item: Deletes the voided line item from the database and
adds back a normal line item (and related tables).

  '';

}

=item delete

Delete this record from the database.

=item replace OLD_RECORD

Replaces the OLD_RECORD with this one in the database.  If there is an error,
returns the error, otherwise returns false.

=item check

Checks all fields to make sure this is a valid record.  If there is
an error, returns the error, otherwise returns false.  Called by the insert
and replace methods.

=item cust_bill

Returns the voided invoice (see L<FS::cust_bill_void>) for this voided line
item.
