=head1 NAME

FS::part_bill_event - Object methods for part_bill_event records

=head1 SYNOPSIS

  use FS::part_bill_event;

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

  $error = $record->insert;

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

  $error = $record->delete;

  $error = $record->check;

=head1 DESCRIPTION

An FS::part_bill_event object represents an invoice event definition -
a callback which is triggered when an invoice is a certain amount of time
overdue.  FS::part_bill_event inherits from
FS::Record.  The following fields are currently supported:

=over 4

=item eventpart - primary key

=item payby - CARD, DCRD, CHEK, DCHK, LECB, BILL, or COMP

=item event - event name

=item eventcode - event action

=item seconds - how long after the invoice date events of this type are triggered

=item weight - ordering for events with identical seconds

=item plan - eventcode plan

=item plandata - additional plan data

=item disabled - Disabled flag, empty or `Y'

=back

=head1 METHODS

=over 4

=item new HASHREF

Creates a new invoice event definition.  To add the invoice event definition 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.

=cut

# the new method can be inherited from FS::Record, if a table method is defined

sub table { 'part_bill_event'; }

=item insert

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

=cut

# the insert method can be inherited from FS::Record

=item delete

Delete this record from the database.

=cut

# the delete method can be inherited from FS::Record

=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.

=cut

# the replace method can be inherited from FS::Record

=item check

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

=cut

# the check method should currently be supplied - FS::Record contains some
# data checking routines

sub check {
  my $self = shift;

}

=item templatename

Returns the alternate invoice template name, if any, or false if there is
no alternate template for this invoice event.

=cut

sub templatename {
  my $self = shift;

=head1 BUGS

The whole "eventcode" idea is bunk.  This should be refactored with subclasses
like part_pkg/ and part_export/
