rdf::vcard::line

RDF::vCard::Line(3pm)					User Contributed Perl Documentation				     RDF::vCard::Line(3pm)

NAME

       RDF::vCard::Line - represents a line within a vCard

DESCRIPTION

       Instances of this class correspond to lines within vCards, though they could potentially be used as basis for other RFC 2425-based formats
       such as iCalendar.

   Constructor
       o   "new(%options)"

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

	   The only options worth worrying about are: property (case-insensitive property name), value (arrayref or single string value),
	   type_parameters (hashref of property-related parameters).

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

	     my $line = RDF::vCard::Line->new(
	       property        => 'email',
	       value	       => 'joe@example.net',
	       type_parameters => { type=>['PREF','INTERNET'] },
	       );
	     print "$line
" if $line =~ /internet/i;

   Methods
       o   "to_string()"

	   Formats the line according to RFC 2425 and RFC 2426.

       o   "add_to_model($model, $node)"

	   Given an RDF::Trine::Model and an RDF::Trine::Node representing the entity (i.e. vcard) that this line belongs to, adds triples to the
	   model for this line.

       o   "property()"

	   Returns the line's property - e.g. "EMAIL".

       o   "property_node()"

	   Returns the line's property as an RDF::Trine::Node that can be used as an RDF predicate. Returns undef if a sensible URI cannot be
	   found.

       o   "property_order()"

	   Returns a string which can be used to sort a list of lines into a sensible order.

       o   "value()"

	   Returns an arrayref for the value. Each item in the arrayref could be a plain scalar, or an arrayref of scalars. For example the
	   arrayref representing this name:

	     N:Smith;John;Edward,James

	   which is the vCard representation of somebody with surname Smith, given name John and additional names (middle names) Edward and James,
	   might be represented with the following "value" arrayref:

	     [
	       'Smith',
	       'John',
	       ['Edward', 'James'],
	     ]

	   or maybe:

	     [
	       ['Smith'],
	       'John',
	       ['Edward', 'James'],
	     ]

	   That's why it's sometimes useful to have a normalised version of it...

       o   "nvalue()"

	   Returns a normalised version of the arrayref for the value. It will always be an arrayref of arrayrefs. For example:

	     [
	       ['Smith'],
	       ['John'],
	       ['Edward', 'James'],
	     ]

       o   "value_node()"

	   Returns the line's value as an RDF::Trine::Node that can be used as an RDF object. For some complex properties (e.g. ADR, GEO, ORG, N,
	   etc) the result is not especially useful.

       o   "value_to_string()"

	   Formats the line value according to RFC 2425 and RFC 2426.

       o   "type_parameters()"

	   Returns the type_parameters hashref. Here be monsters (kinda).
