NAME

Locale::Object::Currency::Converter - convert between currencies

DESCRIPTION

Locale::Object::Currency::Converter allows you to convert between values of currencies represented by Locale::Object::Currency objects.

SYNOPSIS

use Locale::Object::Currency;
use Locale::Object::Currency::Converter;

my $usd = Locale::Object::Currency->new( code => 'USD' );
my $gbp = Locale::Object::Currency->new( code => 'GBP' );
my $eur = Locale::Object::Currency->new( code => 'EUR' );
my $jpy = Locale::Object::Currency->new( code => 'JPY' );

my $converter = Locale::Object::Currency::Converter->new(
                                            from    => $usd,
                                            to      => $gbp,
                                            service => 'XE'
                                           );

my $result    = $converter->convert(5);
my $rate      = $converter->rate;
my $timestamp = $converter->timestamp;

print $converter->use_xe;
print $converter->use_yahoo;

$converter->from($eur);
$converter->to($jpy);
$converter->service('Yahoo');

$converter->refresh;

PREREQUISITES

This module requires Finance::Currency::Convert::XE and Finance::Currency::Convert::Yahoo.

METHODS

new()

my $converter = Locale::Object::Currency::Converter->new();

Creates a new converter object. With no arguments, creates a blank object. Possible arguments are from, to and service, all or none of which may be given. from and to must be Locale::Object::Currency objects. service must be one of either 'XE' or 'Yahoo', to specify the conversion should be done by http://xe.com/ucc/ or http://finance.yahoo.com/ respectively.

use_xe()

print $converter->use_xe;

Returns 1 or 0 depending on whether a use Finance::Currency::Convert::XE; was successful. If 1, you can do conversions using the XE.com service.

use_yahoo()

print $converter->use_yahoo;

Returns 1 or 0 depending on whether a use Finance::Currency::Convert::Yahoo; was successful. If 1, you can do conversions using the finance.yahoo.com service.

from()

$converter->from($eur);

Sets a currency to do conversions from. Takes a Locale::Object::Currency object.

to()

$converter->to($jpy);

Sets a currency to do conversions to. Takes a Locale::Object::Currency object.

service()

$converter->service('Yahoo');

Sets which currency conversion service to use. Depends on two other modules; see use_xe() and use_yahoo() above.

convert()

my $result = $converter->convert(5);

Does the currency conversion. Takes a numeric argument representng the amount of the 'from' currency to convert into the 'to' currency, gives the result. Will croak if you didn't select a conversion service, 'from' and 'to' currency when you did new() or afterwards with the associated methods (see above).

rate()

my $rate = $converter->rate;

Returns the conversion rate between your 'from' currency and your 'to' currency, as of the time you last did a conversion. If you haven't done any conversions yet, will do one first (the result for converting 1 unit of a currency into another currency is the rate) and give you that.

timestamp()

my $timestamp = $converter->timestamp;

Returns the time timestamp of the last time the currency exchange rate was stored, either the last time you did a convert() or a refresh().

refresh()

$converter->refresh;

Will update the stored conversion rate and timestamp by doing another conversion. Doesn't return anything.
