Net::DNS::RR::LOC - DNS LOC resource record
use Net::DNS; $rr = new Net::DNS::RR('name LOC latitude longitude altitude size hp vp');
DNS geographical location (LOC) resource records.
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.
$latitude = $rr->latitude; ($deg, $min, $sec, $ns ) = $rr->latitude; $rr->latitude( 42.357990 ); $rr->latitude( 42, 21, 28.764, 'N' ); $rr->latitude( '42 21 28.764 N' );
When invoked in scalar context, latitude is returned in degrees, a negative ordinate being south of the equator.
When invoked in list context, latitude is returned as a list of separate degree, minute, and second values followed by N or S as appropriate.
Optional replacement values may be represented as single value, list or formatted string. Trailing zero values are optional.
$longitude = $rr->longitude; ($deg, $min, $sec, $ew ) = $rr->longitude; $rr->latitude( 71.014338 ); $rr->latitude( 71, 0, 51.617, 'W' ); $rr->latitude( '71 0 51.617 W' );
When invoked in scalar context, longitude is returned in degrees, a negative ordinate being west of the prime meridian.
When invoked in list context, longitude is returned as a list of separate degree, minute, and second values followed by E or W as appropriate.
$altitude = $rr->altitude;
Represents altitude, in metres, relative to the WGS 84 reference spheroid used by GPS.
$size = $rr->size;
Represents the diameter, in metres, of a sphere enclosing the described entity.
$hp = $rr->hp;
Represents the horizontal precision of the data expressed as the diameter, in metres, of the circle of error.
$vp = $rr->vp;
Represents the vertical precision of the data expressed as the total spread, in metres, of the distribution of possible values.
($lat, $lon) = $rr->latlon;
Returns the latitude and longitude coordinate pair as signed floating-point degrees.
$version = $rr->version;
Version of LOC protocol.
