NAME ^

Weather::Bug::CompactWeather - Simple class interface for a compact weather report.

VERSION ^

This document describes Weather::Bug::CompactWeather version 0.25

SYNOPSIS ^

    use Weather::Bug;

    my $wbug = Weather::Bug->new( 'YOURAPIKEYHERE' );
    my $weather = $wbug->get_live_compact_weather( 'HSTMU', 77030 );

    my $temp = $weather->temp();
    my $rain = $weather->rain_today();
    my $wind = $weather->wind_speed();
    my $dir = $weather->wind_dir();
    print "Temperature: $temp\n",
          "Rain: $rain\n",
          "Wind: $wind from $dir\n";

DESCRIPTION ^

The CompactWeather class wraps the concept of a WeatherBug weather report. The WeatherBug API provides two different weather reports: Live Compact, and Live. This object wraps the compact form which contains the basic information you may want from a weather observation.

INTERFACE ^

The CompactWeather interface provides a factory method that constructs the object from an XML node. It also provides accessor methods for the various pieces of data comprising the weather observation.

Factory Method

Since the CompactWeather object will almost always be created from an XML stream, this class provides a method for constructing a CompactWeather object from the XML response.

from_xml

Extract the weather information from an aws:weather node, such as the ones returned by the getLiveCompactWeather WeatherBug request.

$bug - the Weather::Bug object $w - the aws:weather XML node $creator - either a Weather::Bug::Station or a Weather::Bug object.

If we get a Station, use it internally, otherwise we need to parse the XML to create a station object.

Return a new Weather::Bug::CompactWeather object. Dies on failure.

Accessor Methods

The CompactWeather object provides accessor methods for the following fields:

station

A Weather::Bug::Station object describing the location of the observation. The amount of information in this Station object is determined by how the CompactWeather was created. Weather::Bug::Station::get_live_compact_weather returns the Station used in the request. Weather::Bug::get_live_compact_weather returns a simpler Station object created from the XML stream.

temp

A Weather::Bug::Temperature object containing the current temperature.

rain_today

A Weather::Bug::Quantity object containing the amount of rainfall detected today.

wind_speed

A Weather::Bug::Quantity object containing the current sustained windspeed.

wind_dir

A string listing the current sustained wind direction.

gust_speed

A Weather::Bug::Quantity object containing the windspeed of the most recent gust.

gust_dir

A string listing the direction of the most recent wind gust.

DIAGNOSTICS ^

Unable to create a Station localizing the CompactWeather.

The from_xml method was unable to create a Station object from the incoming XML or the creator object was neither a Weather::Bug nor a Weather::Bug::Station object.

CONFIGURATION AND ENVIRONMENT ^

Weather::Bug requires no configuration files or environment variables.

DEPENDENCIES ^

Moose, XML::LibXML

INCOMPATIBILITIES ^

None reported.

BUGS AND LIMITATIONS ^

No bugs have been reported.
