NAME ^

Weather::Bug::Temperature - Abstraction for temperature with the ability to retrieve data in either C or F.

VERSION ^

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

SYNOPSIS ^

    use Weather::Bug::Temperature;

    my $t = Weather::Bug::Temperature->new( -value => 78, -units => 'F' );

    print "Temperature in Celsius: ", $t->c(), "\n";

DESCRIPTION ^

Much of the information returned from the WeatherBug API is temperature data. Since normal, outside temperatures can be usefully be returned as values on either the Celsius or Fahrenheit scales, this class serves to abstract that distinction for the user.

INTERFACE ^

This class supports one factory method and a set of accessor methods.

Factory Method

from_xml

This method expects an XML::LibXML Node object that describes a temperature. Based on the examples in the WeatherBug API, we expect the temperature value to be the value of the node and the units to be specified in the unit attribute.

Accessor Methods

f

Return the value of the temperature on the Fahrenheit scale. The value returned will have the same digits of precision as the original value.

c

Return the value of the temperature on the Celsius scale. The value returned will have the same digits of precision as the original value.

is_SI

Returns a true value if the original temperature was in Celsius, false otherwise.

stringify

Format the temperature and units as a string. If the temperature is null, the string value will be N/A.

DIAGNOSTICS ^

No node found.

No node was passed to from_xml

Unknown units for temperature.

The supplied units were neither 'C' nor 'F'.

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.
