RDF::Redland::Statement - Redland RDF Statement Class
use RDF::Redland; my $statement1=new RDF::Redland::Statement($statement); my $statement2=new RDF::Redland::Statement($subject,$predicate,$object); ... if($statement->subject->equals($node)) { ... }
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.
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.
Copy a RDF::Redland::Statement.
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.
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.
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.
Return the statement formatted as a string (UTF-8 encoded).
Return non zero if this statement is equal to STATEMENT
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);
Create a new RDF::Redland::Statement object from RDF::Redland::Statement STATEMENT (copy constructor). Use instead:
$s=$old_statement->clone;
