|
use Net::DNS;
|
|
$rr = Net::DNS::RR->new('name GPOS latitude longitude altitude');
|

|
|
=head1 DESCRIPTION
|
|
|
|
Class for DNS Geographical Position (GPOS) resource records.
|
|
|
|
=head1 METHODS
|
|
|
|
The available methods are those inherited from the base class augmented
|
|
by the type-specific methods defined in this package.
|
|
|
|
Use of undocumented package features or direct access to internal data
|
|
structures is discouraged and could result in program termination or
|
|
other unpredictable behaviour.

|
|
|
|
|
=head2 latitude
|
|
|
|
$latitude = $rr->latitude;
|
|
$rr->latitude( $latitude );
|
|
|
|
Floating-point representation of latitude, in degrees.
|
|
|
|
=head2 longitude
|
|
|
|
$longitude = $rr->longitude;
|
|
$rr->longitude( $longitude );
|
|
|
|
Floating-point representation of longitude, in degrees.
|
|
|
|
=head2 altitude
|
|
|
|
$altitude = $rr->altitude;
|
|
$rr->altitude( $altitude );
|
|
|
|
Floating-point representation of altitude, in metres.
