RDF::Redland::Statement(3pm) User Contributed Perl Documentation RDF::Redland::Statement(3pm) NAME
RDF::Redland::Statement - Redland RDF Statement Class SYNOPSIS
use RDF::Redland; my $statement1=new RDF::Redland::Statement($statement); my $statement2=new RDF::Redland::Statement($subject,$predicate,$object); ... if($statement->subject->equals($node)) { ... } DESCRIPTION
Manipulate RDF statements which comprise three RDF::Redland::Node objects. Also used for partial statements which can have empty parts and are used for matching statements in statement queries of the model - see the RDF::Redland::Model. CONSTRUCTORS
new NODE NODE NODE|STATEMENT Create a new statement from nodes or copy an existing statement. If three NODEs are given, make a new statement from them. Each Node can be a Redland::RDF:Node, a Redland::RDF::URI, a perl URI or a string literal. Otherwise STATEMENT must be an existing statement to copy. clone Copy a RDF::Redland::Statement. METHODS
subject [SUBJECT] Get/set the statement subject. When a RDF::Redland::Node SUBJECT is given, sets the subject of the statement, otherwise returns a reference to the statement RDF::Redland::Node subject. predicate [PREDICATE] Get/set the statement predicate. When RDF::Redland::Node PREDICATE is given, sets the predicate of the statement, otherwise returns a reference to the statement RDF::Redland::Node predicate. object [OBJECT] Get/set the statement object. When RDF::Redland::Node OBJECT is given, sets the object of the statement, otherwise returns a reference to the statement RDF::Redland::Node object. as_string Return the statement formatted as a string (UTF-8 encoded). equals STATEMENT Return non zero if this statement is equal to STATEMENT OLD METHODS
new_from_nodes SUBJECT PREDICATE OBJECT Create a new RDF::Redland::Statement with the given RDF::Redland::Node objects as parts (or undef when empty for a partial statement). Use instead: $a=new RDF::Redland::Statement($subject, $predicate, $object); new_from_statement STATEMENT Create a new RDF::Redland::Statement object from RDF::Redland::Statement STATEMENT (copy constructor). Use instead: $s=$old_statement->clone; SEE ALSO
