Thanks for the help! (1 Reply)

rdf::redland::statement
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;
