NAME
Weather::Com::AirPressure - class containing barometric pressure data
SYNOPSIS
#!/usr/bin/perl -w
use Weather::Com::Finder;
# you have to fill in your ids from weather.com here
my $PartnerId = 'somepartnerid';
my $LicenseKey = 'mylicense';
my %weatherargs = (
'partner_id' => $PartnerId,
'license' => $LicenseKey,
);
my $weather_finder = Weather::Com::Finder->new(%weatherargs);
my @locations = $weather_finder->find('Heidelberg');
my $currconditions = $locations[0]->current_conditions();
print "Barometric pressure is ",
$currconditions->pressure()->pressure(), "
";
print "and it's ", $currconditions->pressure()->tendency(), "
";
DESCRIPTION
Via Weather::Com::AirPressure one can access the barometric pressure and its tendency.
This class will not be updated automatically with each call to one of its methods. You need to call the "pressure()" method of the parent
object again to update your object.
CONSTRUCTOR
You usually would not construct an object of this class yourself. This is implicitely done when you call the "pressure()" method of one
current conditions or forecast object.
METHODS
pressure()
Returns the barometric pressure.
tendency([$language])
Returns the tendency of the barometric pressure.
This attribute is dynamic language enabled.
