=head1 NAME
Weather::Com::Simple - Simple Wrapper around the L<Weather::Com::Cached> API
=head1 SYNOPSIS
use Data::Dumper;
use Weather::Com::Simple;
# define parameters for weather search
my %params = (
'partner_id' => 'somepartnerid',
'license' => '12345678',
'place' => 'Heidelberg',
);
# instantiate a new weather.com object
my $simple_weather = Weather::Com::Simple->new(%params);
my $weather = $simple_weather->get_weather();
print Dumper($weather);
=head1 DESCRIPTION
I<Weather::Com::Simple> is a very high level wrapper around I<Weather::Com::Cached>.
You provide a place to search for (e.g. a city or "city, country") and you'll get
back a simple hash containing some usefull weather information about all locations
whose name matches to the search string.
=head1 CONSTRUCTOR
=head2 new(hash or hashref)
The constructor takes the same hash or hashref as L<Weather::Com::Cached> does.
Please refer to that documentation for further details.
Except from the L<Weather::Com::Cached> parameters this constructor takes a
parameter I<place> which defines the location to search for. It is not
possible to provide the location to search to the I<get_weather()> method!
=head1 METHODS
=head2 get_weather()
This method invokes the L<Weather::Com::Cached> API to fetch some
weather information and returns an arrayref containing one
or many hashrefs with some high level weather information.
If no location matching the search string is found, it returns
I<undef>.
When you construct a L<Weather::Com::Simple> object like shown in
the synopsis above, the arrayref returned has the following structure:
$VAR1 = [
{
'place' => 'Heidelberg, Germany',
'celsius' => '0',
'fahrenheit' => '32',
'temperature_celsius' => '0',
'temperature_fahrenheit' => '32'
'windchill_celsius' => '-6',
'windchill_fahrenheit' => '21',
'windspeed_kmh' => '26',
'windspeed_mph' => '16',
'wind' => '16 mph 26 km/h from the North Northeast',
'updated' => '11:50 AM Local on January 26, 2005',
'conditions' => 'Partly Cloudy',
'pressure' => '30.21 in / 1023.0 hPa',
'humidity' => '60',
},
{
'place' => 'Heidelberg, KY',
...
},
{
'place' => 'Heidelberg, MS',
...
}
];
