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

NAME

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

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.

   Constructor
       o   "new(%options)"

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

	   The only option worth worrying about is 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;

   Methods
       o   "to_string()"

	   Formats the object according to RFC 2425 and RFC 2426.

       o   "to_jcard()"

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

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

       o   "add_to_model($model)"

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

       o   "node()"

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

       o   "entity_order()"

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

       o   "profile()"

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

       o   "lines()"

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

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

       o   "add($line)"

	   Add a RDF::vCard::Line.

       o   "get($property)"

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

	   e.g.

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

       o   "matches($property, $regexp)"

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

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

       o   "add_component($thing)"

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

       o   "components"

	   Lists nested entities within this one.

NAME

       RDF::Trine::Graph - Materialized RDF Graphs for testing isomorphism

VERSION

       This document describes RDF::Trine::Graph version 1.000

SYNOPSIS

	 use RDF::Trine::Graph;
	 my $a = RDF::Trine::Graph->new( $model_a );
	 my $b = RDF::Trine::Graph->new( $model_b );
	 print "graphs are " . ($a->equals( $b ) ? "the same" : "different");

DESCRIPTION

       RDF::Trine::Graph provdes a mechanism for testing graph isomorphism based on graph triples from either a RDF::Trine::Model or a
       RDF::Trine::Iterator.  Isomorphism testing requires materializing all of a graph's triples in memory, and so should be used carefully in
       situations with large graphs.

METHODS

       "new ( $model )"
       "new ( $iterator )"
	   Returns a new graph from the given RDF::Trine::Model or RDF::Trine::Iterator::Graph object.

       "equals ( $graph )"
	   Returns true if the invocant and $graph represent two equal RDF graphs (e.g.  there exists a bijection between the RDF statements of
	   the invocant and $graph).

       "is_subgraph_of ( $graph )"
	   Returns true if the invocant is a subgraph of $graph. (i.e. there exists an injection of RDF statements from the invocant to $graph.)

       "injection_map ( $graph )"
	   If the invocant is a subgraph of $graph, returns a mapping of blank node identifiers from the invocant graph to $graph as a hashref.
	   Otherwise returns false. The solution is not always unique; where there exist multiple solutions, the solution returned is arbitrary.

       "split_blank_statements"
	   Returns two array refs, containing triples with blank nodes and triples without any blank nodes, respectively.

       "get_statements"
	   Returns a RDF::Trine::Iterator::Graph object for the statements in this graph.

       "error"
	   Returns an error string explaining the last failed "equal" call.
