RDF::Redland::Iterator - phpMan

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.
