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

• "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 $line = RDF::vCard::Line->new(
      property        => 'email',
      value           => '[email protected]',
      type_parameters => { type=>['PREF','INTERNET'] },
      );
    print "$line\n" if $line =~ /internet/i;
  

Methods

• "to_string()"

  Formats the line according to RFC 2425 and RFC 2426.

• "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.

• "property()"

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

• "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.

• "property_order()"

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

• "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...

• "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'],
    ]
  

• "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.

• "value_to_string()"

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

• "type_parameters()"

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