=head1 NAME

RDF::vCard::Entity - represents a single vCard

=head1 DESCRIPTION

Instances of this class correspond to individual vCard objects, though
it could potentially be used as basis for other RFC 2425-based formats
such as iCalendar.

=head2 Constructor

=over

=item * C<< new(%options) >>

Returns a new RDF::vCard::Entity object.

The only option worth worrying about is B<profile> which sets the
profile for the entity. This defaults to "VCARD".

RDF::vCard::Entity overloads stringification, so you can do the following:

  my $vcard = RDF::vCard::Entity->new;
  print $vcard if $vcard =~ /VCARD/i;

=back

=head2 Methods

=over

=item * C<< to_string() >>

Formats the object according to RFC 2425 and RFC 2426.

=item * C<< to_jcard() >>

Formats the object according to L<http://microformats.org/wiki/jcard>.

C<< to_jcard(1) >> will return the same data but without the JSON stringification.

=item * C<< add_to_model($model) >>

Given an RDF::Trine::Model, adds triples to the model for this entity.

=item * C<< node() >>

Returns an RDF::Trine::Node::Blank identifying this entity.

=item * C<< entity_order() >>

Returns a string along the lines of "Surname;Forename" useful for
sorting a list of entities.

=item * C<< profile() >>

Returns the entity type - e.g. "VCARD".

=item * C<< lines() >>

Returns an arrayref of L<RDF::vCard::Line> objects in the order they
were originally added.

This excludes the "BEGIN:VCARD" and "END:VCARD" lines.

=item * C<< add($line) >>

Add a L<RDF::vCard::Line>.

=item * C<< get($property) >>

Returns a list of L<RDF::vCard::Line> objects for the given property.

e.g.

  print "It has an address!\n" if ($vcard->get('ADR'));

=item * C<< matches($property, $regexp) >>

Checks to see if a property's value matches a regular expression.

  print "In London\n" if $vcard->matches(ADR => /London/);

=item * C<< add_component($thing) >>

Adds a nested entity within this one. This method is unused for vCard, but
is a hook for the benefit of L<RDF::iCalendar>.

=item * C<< components >>

Lists nested entities within this one.
