NAME

       HTML::Microformats::Datatype::Interval - concrete periods of time

SYNOPSIS

        my $interval = HTML::Microformats::Datatype::Interval->new($span);
        print "$interval\n";

DESCRIPTION

   Constructors
       "$i = HTML::Microformats::Datatype::Interval->new($span)"
           Creates a new HTML::Microformats::Datatype::Interval object.

           $span is a DateTime::Span object.

       "$i = HTML::Microformats::Datatype::Interval->parse($string, $elem, $context)"
           Creates a new HTML::Microformats::Datatype::Interval object.

           $string is an interval represented in ISO 8601 format, for example: '2010-01-01/P1Y'
           or '2010-01-01/2011-01-01'. $elem is the XML::LibXML::Element being parsed. $context
           is the document context.

           This constructor supports a number of experimental microformat interval patterns. e.g.

            <div class="interval">
             <span class="d">4</span> days starting from
             <abbr class="start" title="2010-01-01">2010</abbr>
            </div>

   Public Methods
       "$span = $i->span"
           Returns a DateTime::Span object.

       "$span = $i->to_string"
           Returns an ISO 8601 formatted string representing the interval.

       "$d->datatype"
           Returns an the RDF datatype URI representing the data type of this literal.

   Function
       "compare($a, $b)"
           Compares intervals $a and $b. Return values are as per 'cmp' (see perlfunc).

           This function is not exported by default.

           Can also be used as a method:

            $a->compare($b);
