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;
