Weather::Cached - Perl extension for getting weather information from weather.com
SYNOPSIS
use Data::Dumper;
use Weather::Cached;
# define parameters for weather search
my %params = (
'cache' => '/tmp/weathercache',
'current' => 1,
'forecast' => 3,
'links' => 1,
'units' => 's',
'proxy' => 'http://proxy.sonstwo.de',
'timeout' => 250,
'debug' => 1,
'partner_id' => 'somepartnerid',
'license' => '12345678',
);
# instantiate a new weather.com object
my $cached_weather = Weather::Cache->new(%params);
# search for locations called 'Heidelberg'
my $locations = $cached_weather->search('Heidelberg')
or die "No location found!\n";
# and then get the weather for each location found
foreach (keys %{$locations}) {
my $weather = $cached_weather->get_weather($_);
print Dumper($weather);
}DESCRIPTION
Weather::Cache is a Perl module that provides low level OO interface to gather all weather information that is provided by weather.com.
This module implements the caching business rules that apply to all applications programmed against the xoap API of weather.com. Except from the cache parameter to be used while instantiating a new object instance, this module has the same API than Weather::Com. It's only a simple caching wrapper around it.
Although it's really simple, the module uses Storable methods lock_store and lock_retrieve to implement shared locking for reading cache files and exclusive locking for writing to chache files. By this way the same cache files should be able to be used by several application instances using Weather::Cache.
For a more high level interface please have a look at Weather::Simple that provides the same simple API than Weather::Underground does.
You'll need to register at weather.com to to get a free partner id and a license key to be used within all applications that you want to write against weather.com's xoap interface.

CONSTRUCTOR
new(hash or hashref)
This constructor takes the same hash or hashref as Weather::Com does. Please refer to that documentation for further details.
Except from the Weather::Com's parameters this constructor takes a parameter cache which defines the path to a directory into which all cache files will be put. The cache directory defaults to '.'.
METHODS
That's all the same as for Weather::Com.
