NAME

       Iterator - marks a position in a data structure

SYNOPSIS

       #include <Unidraw/iterator.h>

DESCRIPTION

       An  iterator  marks a position in a data structure, generally during a traversal of some sort.  For example, an iterator keeps track of the
       current position when iterating through a list of elements.  Unidraw's Iterator class serves this purpose in  conjunction  with	ULists	or
       objects that use them.

PUBLIC OPERATIONS

       Iterator()
       Iterator(Iterator&)
	      Construct a new iterator.  The second constructor initializes the iterator's value to that of the given iterator.

       virtual void SetValue(void*)
       virtual void* GetValue()
	      Classes that use an iterator must store position information in it.  These operations set and get the this information.

NAME

       RDF::Trine::Iterator::Graph::Materialized - Materialized graph class

VERSION

       This document describes RDF::Trine::Iterator::Graph::Materialized version 1.000

SYNOPSIS

	use RDF::Trine::Iterator;

	my $iterator = RDF::Trine::Iterator::Graph::Materialized->new( @data );
	while (my $statement = $iterator->next) {
	       # do something with $statement
	}

	my $iterator = RDF::Trine::Iterator::Graph->new( &code );
	my $miter = $iterator->materialize;
	while (my $statement = $miter->next) {
	       # do something with $statement
	}
	$miter->reset; # start the iteration again
	while (my $statement = $miter->next) {
	    # ...
	}

METHODS

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

       "new ( @results, %args )"
	   Returns a new materialized graph interator. Results must be a reference to an array containing individual results.

       "reset"
	   Returns the iterator to its starting position.

       "next"
	   Returns the next item in the iterator.

       "length"
	   Returns the number of elements in the iterator.
