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

• 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\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).
