NAME

Data::Validate::Japanese - Validate Japanese Input

SYNOPSIS

  use Data::Validate::Japanese;
  my $dvj = Data::Validate::Japanese->new;
  $ok = $dvj->is_hiragana($data);
  $ok = $dvj->is_katakana($data);
  $ok = $dvj->is_kanji($data);
  $ok = $dvj->is_h_katakana($data);

  $dvj->contains_only($value, { 
    hiragana   => 1,
    katakana   => 1,
    kanji      => 1,
    h_katakana => 1,
    ascii      => 1
  });

DESCRIPTION

Data::Validate::Japanese aims to be the base (or at least, the common link between) the myriad different data validator infrastructures, and their Japanese-specific extensions. There are just too many validators with too many different interfaces, but it's not like the core handling of Japanese characters change.

METHODS

All methods return true or false unless otherwise stated. All methods also expect Japanese characters that have successfully been decoded to Perl's internal unicode format.
