=head1 NAME
FS::sector_coverage - Object methods for sector_coverage records
=head1 SYNOPSIS
use FS::sector_coverage;
$record = new FS::sector_coverage \%hash;
$record = new FS::sector_coverage { 'column' => 'value' };
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::sector_coverage object represents a coverage map for a sector at
a specific signal strength level. FS::sector_coverage inherits from
FS::Record. The following fields are currently supported:
=over 4
=item coveragenum
primary key
=item sectornum
L<FS::tower_sector> foreign key
=item db_loss
The maximum path loss shown on this map, in dB.
=item geometry
A GeoJSON Geometry object for the area covered at this level.
=back
=head1 METHODS
=over 4
=item new HASHREF
Creates a new map. To add the example 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 { 'sector_coverage'; }
=item insert
Adds this record to the database. If there is an error, returns the error,
otherwise returns false.
=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.
=cut
# the replace method can be inherited from FS::Record
=item check
Checks all fields to make sure this is a valid example. 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;
my $error =
$self->ut_numbern('coveragenum')
|| $self->ut_number('sectornum')
|| $self->ut_number('db_loss')
;
return $error if $error;
if ( length($self->geometry) ) {
# make sure it parses at least
local $@;
my $data = eval { decode_json($self->geometry) };
if ( $@ ) {
# limit the length, in case it decides to return a large chunk of data
return "Error parsing coverage geometry: ".substr($@, 0, 100);
}
}
$self->SUPER::check;
}
