NAME

       RDF::Redland::Stream - Redland RDF Stream of RDF::Redland::Statement objects Class

SYNOPSIS

	 use RDF::Redland;

	 ...
	 my $stream=$model->serialise;
	 while($stream && !$stream->end) {
	   my $statement=$stream->current;
	   ...
	   $stream->next;
	 }

DESCRIPTION

       Represents a sequence of RDF::Redland::Statement objects passed between various Redland objects.

CONSTRUCTORS

       No public constructors - are created and returned from various methods of classes including RDF::Redland::Model and RDF::Redland::Parser

METHODS

       end Returns non 0 if the stream is finished.

       current
	   Returns the current RDF::Redland::Statement object in the stream or undef if the stream is finished.

       next
	   Moves to the next RDF::Redland::Statement object in the stream.  Returns non-zero if the stream is finished.

       context
	   Returns the context RDF::Redland::Node object in the stream or undef if the stream is finished.

NAME

       RDF::Redland::Iterator - Redland RDF Iterator Class

SYNOPSIS

	 use RDF::Redland;

	 ...
	 my $iterator=$model->targets_iterator($source_node, $arc_node);
	 while($iterator && !$iterator->end) {
	   my $node=$iterator->current;
	   ...
	   $iterator->next;
	 }

DESCRIPTION

       This class is used to return lists of RDF::Redland::Node objects from a method that returns an RDF::Redland::Iterator - commonly one of the
       get_sources_iterator, get_targets_iterator or get_arcs_iterator methods of the RDF::Redland::Model class.

       This allows efficient retrieval of long lists of RDF::Redland::Node objects but isn't really very Perl-friendly.  The get_sources,
       get_targets or get_arcs methods of RDF::Redland::Model class return Perl lists and the get_source, get_target and get_arc methods return
       single arbitrary results.

CONSTRUCTORS

       No public constructors - are created and returned from various methods of classes including RDF::Redland::Model

METHODS

       end Return non 0 if the iterator has finished

       current
	   Returns the current RDF::Redland::Node object from the iteration or undef if the iteration is finished.

       next
	   Moves the iterator to the next item, returns undef if the iteration is finished.

       context
	   Returns the context RDF::Redland::Node object from the iteration or undef if the iteration is finished.
