NAMEAttean::ListIterator − Iterator implementation backed by a list/array of values

---

VERSIONThis document describes Attean::ListIterator version 0.030

---

SYNOPSIS​ 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

DESCRIPTIONThe Attean::ListIterator class represents a typed iterator. It conforms to the Attean::API::RepeatableIterator role. The Attean::ListIterator constructor requires two named arguments: values An array reference containing the items to iterate over. item_type A string representing the type of the items that will be returned from the iterator.

---

METHODSreset 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. size Returns the number of elements still remaining in the iterator until it is fully consumed or until reset is called.
