NAME

       Text::vCard::Node - Object for each node (line) of a vCard

SYNOPSIS

         use Text::vCard::Node;

         my %data = (
           'param' => {
             'HOME,PREF' => 'undef',
           },
           'value' => ';;First work address - street;Work city;London;Work PostCode;CountryName',
         );

         my $node = Text::vCard::Node->new({
           node_type => 'address', # Auto upper cased
           fields => ['po_box','extended','street','city','region','post_code','country'],
           data => \%data,
         });

DESCRIPTION

       Package used by Text::vCard so that each element: ADR, N, TEL etc are objects.

       You should not need to use this module directly, Text::vCard does it all for you.

METHODS

   new()
         my $node = Text::vCard::Node->new({
           node_type => 'address', # Auto upper cased
           fields => \['po_box','extended','street','city','region','post_code','country'],
           data => \%data,
         });

   value()
         # Get the value for a standard single value node
         my $value = $node->value();

         # Or set the value
         $node->value('New value');

   other()'s
         # The fields supplied in the conf area also methods.
         my $po_box = $node->po_box(); # if the node was an ADR.

         # Set the value.
         my $street = $node->street('73 Sesame Street');

   node_type
       Returns the type of the node itself, e.g. ADR.

   unit()
         my @units = @{ $org_node->unit() };
         $org_node->unit( [ 'Division', 'Department', 'Sub-department' ] );

       As ORG allows unlimited numbers of 'units' as well as and organisation 'name', this method
       is a specific case for accessing those values, they are always returned as an array
       reference, and should always be set as an array reference.

   types()
         my @types = $node->types();

         # or
         my $types = $node->types();

       This method will return an array or an array ref depending on the calling context of types
       associated with the $node, undef is returned if there are no types.

       All types returned are lower case.

   is_type()
         if ( $node->is_type($type) ) {

             # ...
         }

       Given a type (see types() for a list of those set) this method returns 1 if the $node is
       of that type or undef if it is not.

   is_pref();
         if ( $node->is_pref() ) {
             print "Prefered node";
         }

       This method is the same as is_type (which can take a value of 'pref') but it specific to
       if it is the preferred node. This method is used to sort when returning lists of nodes.

   add_types()
         $address->add_types('home');

         my @types = qw(home work);
         $address->add_types( \@types );

       Add a type to an address, it can take a scalar or an array ref.

   remove_types()
         $address->remove_types('home');

         my @types = qw(home work);
         $address->remove_types( \@types );

       This method removes a type from an address, it can take a scalar or an array ref.

       undef is returned when in scalar context and the type does not match, or when in array ref
       context and none of the types match, true is returned otherwise.

   group()
         my $group = $node->group();

       If called without any arguments, this method returns the group name if a node belongs to a
       group. Otherwise undef is returned.

       If an argument is supplied then this is set as the group name.

       All group names are always lowercased.

       For example, Apple Address book used 'itemN' to group it's custom X-AB... nodes with a TEL
       or ADR node.

   export_data()
         my $value = $node->export_data();

       This method returns the value string of a node.  It is only needs to be called when
       exporting the information back out to ensure that it has not been altered.

   as_string
       Returns the node as a formatted string.

   NOTES
       If a node has a param of 'quoted-printable' then the value is escaped (basically
       converting Hex return into \r\n as far as I can see).

   EXPORT
       None by default.
