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 0.20
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'.
