# ABSTRACT: Class for locale objects instantiated from pre-defined data
__END__

=head1 NAME
DateTime::Locale::FromData - Class for locale objects instantiated from pre-defined data
=head1 VERSION
version 1.24
=head1 SYNOPSIS
my $locale = DateTime::Locale::FromData->new(%lots_of_data)
=head1 DESCRIPTION
This class is used to represent locales instantiated from the data in the
DateTime::Locale::Data module.
=head1 METHODS
This class provides the following methods:
=head2 $locale->code
The complete locale id, something like "en-US".
=head2 $locale->language_code
The language portion of the code, like "en".
=head2 $locale->script_code
The script portion of the code, like "Hant".
=head2 $locale->territory_code
The territory portion of the code, like "US".
=head2 $locale->variant_code
The variant portion of the code, like "POSIX".
=head2 $locale->name
The locale's complete name, which always includes at least a language
component, plus optional territory and variant components. Something like
"English United States". The value returned will always be in English.
=head2 $locale->language
=head2 $locale->script
=head2 $locale->territory
=head2 $locale->variant
The relevant component from the locale's complete name, like "English"
or "United States".
=head2 $locale->native_name
The locale's complete name in localized form as a UTF-8 string.
=head2 $locale->native_language
=head2 $locale->native_script
=head2 $locale->native_territory
=head2 $locale->native_variant
The relevant component from the locale's complete native name as a UTF-8
string.
=head2 $locale->month_format_wide
=head2 $locale->month_format_abbreviated
=head2 $locale->month_format_narrow
=head2 $locale->month_stand_alone_wide
=head2 $locale->month_stand_alone_abbreviated
=head2 $locale->month_stand_alone_narrow
=head2 $locale->day_format_wide
=head2 $locale->day_format_abbreviated
=head2 $locale->day_format_narrow
=head2 $locale->day_stand_alone_wide
=head2 $locale->day_stand_alone_abbreviated
=head2 $locale->day_stand_alone_narrow
=head2 $locale->quarter_format_wide
=head2 $locale->quarter_format_abbreviated
=head2 $locale->quarter_format_narrow
=head2 $locale->quarter_stand_alone_wide
=head2 $locale->quarter_stand_alone_abbreviated
=head2 $locale->quarter_stand_alone_narrow
=head2 $locale->am_pm_abbreviated
=head2 $locale->era_wide
=head2 $locale->era_abbreviated
=head2 $locale->era_narrow
These methods all return an array reference containing the specified data.
The methods with "format" in the name should return strings that can be used a
part of a string, like "the month of July". The stand alone values are for use
in things like calendars as opposed to a sentence.
The narrow forms may not be unique (for example, in the day column heading for
a calendar it's okay to have "T" for both Tuesday and Thursday).
The wide name should always be the full name of thing in question. The narrow
name should be just one or two characters.
=head2 $locale->date_format_full
=head2 $locale->date_format_long
=head2 $locale->date_format_medium
=head2 $locale->date_format_short
=head2 $locale->time_format_full
=head2 $locale->time_format_long
=head2 $locale->time_format_medium
=head2 $locale->time_format_short
=head2 $locale->datetime_format_full
=head2 $locale->datetime_format_long
=head2 $locale->datetime_format_medium
=head2 $locale->datetime_format_short
These methods return strings appropriate for the C<< DateTime->format_cldr >>
method.
=head2 $locale->format_for($name)
These are accessed by passing a name to C<< $locale->format_for(...) >>,
where the name is a CLDR-style format specifier.
The return value is a string suitable for passing to C<< $dt->format_cldr >>,
so you can do something like this:
print $dt->format_cldr( $dt->locale->format_for('MMMdd') )
which for the "en" locale would print out something like "08 Jul".
Note that the localization may also include additional text specific to the
locale. For example, the "MMMMd" format for the "zh" locale includes the
Chinese characters for "day" (日) and month (月), so you get something like
"S<8月23日>".
=head2 $locale->available_formats
This should return a list of all the format names that could be passed
to C<< $locale->format_for >>.
See the documentation for individual locales for details and examples of these
formats. The format names that are available vary by locale.
=head2 $locale->glibc_datetime_format
=head2 $locale->glibc_date_format
=head2 $locale->glibc_date_1_format
=head2 $locale->glibc_time_format
=head2 $locale->glibc_time_12_format
These methods return strings appropriate for the C<< DateTime->strftime >>
method. However, you are strongly encouraged to use the other format methods,
which use the CLDR format data. They are primarily included for the benefit
for L<DateTime::Format::Strptime>.
=head2 $locale->version
The CLDR version from which this locale was generated.
=head2 $locale->prefers_24_hour_time
Returns a boolean indicating whether or not the locale prefers 24-hour time.
=head2 $locale->first_day_of_week
Returns a number from 1 to 7 indicating the I<local> first day of the
week, with Monday being 1 and Sunday being 7.
=head2 $locale->locale_data
Returns the original data used to create this locale as a hash. This is here
to facilitate creating custom locale that via
C<DateTime::Locale->register_data_locale>.
