RDF::Trine::Iterator::UserhContributed Perl DocuRDF::Trine::Iterator::Graph(3)

NAME
       RDF::Trine::Iterator::Graph - Iterator class for	graph query results

VERSION
       This document describes RDF::Trine::Iterator::Graph version 1.015

SYNOPSIS
	use RDF::Trine::Iterator::Graph;

	my $iterator = RDF::Trine::Iterator::Graph->new( \&data	);
	while (my $st =	$iterator->next) {
	  # $st	is a RDF::Trine::Statement object
	  print	$st->as_string;
	}

METHODS
       Beyond the methods documented below, this class inherits	methods	from
       the RDF::Trine::Iterator	class.

       "new ( \@results, %args )"
       "new ( \&results, %args )"
	   Returns a new SPARQL	Result interator object. Results must be
	   either an reference to an array containing results or a CODE
	   reference that acts as an iterator, returning successive items when
	   called, and returning undef when the	iterator is exhausted.

	   $type should	be one of: bindings, boolean, graph.

       "as_bindings ( $s, $p, $o )"
	   Returns the iterator	as a Bindings iterator,	using the supplied
	   triple nodes	to determine the variable bindings.

       "materialize"
	   Returns a materialized version of the current graph iterator.  The
	   materialization process will	leave this iterator empty. The
	   materialized	iterator that is returned should be used for any
	   future need for the iterator's data.

       "unique"
	   Returns a Graph iterator that ensures the returned statements are
	   unique. While the underlying	RDF graph is the same regardless of
	   uniqueness, the iterator's serialization methods assume the results
	   are unique, and so use this method before serialization.

	   Uniqueness is opt-in	for efficiency concerns	-- this	method
	   requires O(n) memory, and so	may have noticeable effects on large
	   graphs.

       "is_graph"
	   Returns true	if the underlying result is an RDF graph.

       "as_string ( $max_size [, \$count] )"
	   Returns a string table serialization	of the stream data.

       "as_xml ( $max_size )"
	   Returns an XML serialization	of the stream data.

       "print_xml ( $fh, $max_size )"
	   Prints an XML serialization of the stream data to the filehandle
	   $fh.

       "as_json	( $max_size )"
	   Returns a JSON serialization	of the stream data.

       "as_hashref"
	   Returns a hashref representing the model in an RDF/JSON-like
	   manner.

	   See "as_hashref" at RDF::Trine::Model for full documentation	of the
	   hashref format.

       "construct_args"
	   Returns the arguments necessary to pass to the stream constructor
	   _new	to re-create this stream (assuming the same closure as the
	   first
