NAME
Locale::Object::Currency - currency information objects
DESCRIPTION
Locale::Object::Country
allows you to create objects containing information about countries such as their ISO codes, currencies and so on.
SYNOPSIS
use Locale::Object::Currency;
my $usd = Locale::Object::Currency->new( country_code => 'us' );
my $name = $usd->name;
my $code = $usd->code;
my $code_numeric = $usd->code_numeric;
my $symbol = $usd->symbol;
my $subunit = $usd->subunit;
my $subunit_amount = $usd->subunit_amount;
my @countries = $usd->countries;
METHODS
new()
my $usd = Locale::Object::Currency->new( country_code => 'us' );
The new
method creates an object. It takes a single-item hash as an argument - valid options to pass are ISO 3166 values - 'code' and 'code_numeric'; also 'country_code', which is an alpha2 country code (see Locale::Object::DB::Schemata for details on these). If you give a country code, a currency object will be created representing the currency of the country you specified.
The objects created are singletons; if you try and create a currency object when one matching your specification already exists, new()
will return the original one.
name(), code(), code_numeric(), symbol(), subunit(), subunit_amount()
my $name = $country->name;
These methods retrieve the values of the attributes in the object whose name they share.
countries()
my @countries = $usd->countries;
Returns an array (in array context, otherwise a reference) of Locale::Object::Country objects with their ISO 3166 alpha2 codes as keys (see Locale::Object::DB::Schemata for more details on those) for all countries using this currency in array context, or a reference in scalar context. The objects have their own attribute methods, so you can do things like this for example:
foreach my $place (@countries)
{
print $place->name, "\n";
}
Which will list you all the countries that use in that currency. See the documentation for Locale::Object::Country for a listing of country attributes. Note that you can chain methods as well.
foreach my $place (@countries)
{
print $place->continent->name, "\n";
}
KNOWN BUGS
The database of currency information is not perfect by a long stretch. If you find mistakes or missing information, please send them to the author.
