Attean::ListIterator - Iterator implementation backed by a list/array of values
This document describes Attean::ListIterator version 0.010
use v5.14; use Attean; my @values = map { Attean::Literal->new($_) } (1,2,3); my $iter = Attean::ListIterator->new( values => \@values, item_type => 'Attean::API::Term', ); say $iter->next->value; # 1 say $iter->next->value; # 2 say $iter->next->value; # 3
The Attean::ListIterator class represents a typed iterator. It conforms to the Attean::API::RepeatableIterator role.
The Attean::ListIterator constructor requires two named arguments:
An array reference containing the items to iterate over.
A string representing the type of the items that will be returned from the iterator.
reset
Resets the iterator's internal state so that iteration begins again at the beginning of the values array.
next
Returns the iterator's next item, or undef upon reaching the end of iteration.
