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. SEE ALSO
UList(3U) Unidraw 11 June 1990 Iterator(3U)

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. BUGS
