=head1 DESCRIPTION
=head2 Constructor
=over 4
=item C<< $str = HTML::Microformats::Datatype::String->new($text, [$lang]) >>
Creates a new HTML::Microformats::Datatype::String object.
=back
=cut
sub new
{
my $class = shift;
my $rv = {};
$rv->{'string'} = shift;
$rv->{'lang'} = shift;
bless $rv, $class;
}
=head2 Public Methods
=over 4
=item C<< $str->lang >>
Return the language code.
=cut
sub lang
{
my $this = shift;
return $this->{'lang'};
}
=item C<< $str->to_string >>
Return a plain (scalar) string.
=back
=cut
sub to_string

return $this->{'string'};
}
sub TO_JSON
{
my $this = shift;
return $this->{'string'};
}
=head2 Functions
=over 4
=item C<< $str = ms($text, [$element]) >>
Construct a new HTML::Microformats::Datatype::String object from a
scalar, plus XML::LibXML::Element. If $element is undef, then returns
the plain (scalar) string itself.
This function is exported by default.
(Note: the name 'ms' originally stood for 'Magic String'.)
=cut
sub ms
{
my ($rv, $dom);
$rv->{string} = shift;
$dom = shift || return $rv->{string};
$rv->{lang} = $dom->getAttribute('data-cpan-html-microformats-lang');
$rv->{xpath} = $dom->getAttribute('data-cpan-html-microformats-nodepath');
$rv->{xml} = $dom->toString;
$rv->{dom} = $dom;
bless $rv, __PACKAGE__;
}
=item C<< isms($str) >>
Returns true iff $str is blessed as a HTML::Microformats::Datatype::String
object.
This function is exported by default.
=cut
sub isms
{
my $this = shift;
return (__PACKAGE__ eq ref $this);
}
=item C<< $c = concat($a, $b, [$reverse]) >>
Concatenates two strings.
If the language of string $b is null or the same as $a, then the
resultant string has the same language as $a. Otherwise the result
has no language.
If $reverse is true, then the strings are concatenated with $b
preceding $a.
This function is not exported by default.
Can also be used as a method:
$c = $a->concat($b);
=cut
sub concat
{
my $a = shift;
my $b = shift;
my $rev = shift;
if ($rev)
{
($a, $b) = ($b, $a);
}
unless (ref $a)
{ $a = { string => $a }; }
unless (ref $b)
{ $b = { string => $b }; }
my $rv = {};
$rv->{string} = $a->{string}.$b->{string};
if (!$b->{lang} || (lc($a->{lang}) eq lc($b->{lang})))
{
$rv->{lang} = $a->{lang};
}
bless $rv, __PACKAGE__;
}
=item C<< compare($a, $b) >>
Compares two strings alphabetically. Language is ignored.
Return values are as per 'cmp' (see L<perlfunc>).
This function is not exported by default.
Can also be used as a method:
$a->compare($b);
=back
=cut
sub compare
{
my $a = shift;
my $b = shift;
return "$a" cmp "$b";
}
