=head1 NAME

FS::cust_tax_location - Object methods for cust_tax_location records

=head1 SYNOPSIS

  use FS::cust_tax_location;

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

  $error = $record->insert;

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

  $error = $record->delete;

  $error = $record->check;

=head1 DESCRIPTION

An FS::cust_tax_location object represents a mapping between a customer and
a tax location.  FS::cust_tax_location inherits from FS::Record.  The
following fields are currently supported:

=over 4

=item custlocationnum

primary key

=item data_vendor

a tax data vendor

=item zip 

=item state

=item plus4hi

the upper bound of the last 4 zip code digits

=item plus4lo

the lower bound of the last 4 zip code digits

=item default_location

'Y' when this record represents the default for zip

=item geocode - the foreign key into FS::part_pkg_tax_rate and FS::tax_rate


=back

=head1 METHODS

=over 4

=item new HASHREF

Creates a new cust_tax_location.  To add the cust_tax_location 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

sub table { 'cust_tax_location'; }

=item insert

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

=cut

=item delete

Delete this record from the database.

=cut

=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

=item check

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