NAME¶
Attean::ListIterator - Iterator implementation backed by a list/array of values
VERSION¶
This document describes Attean::ListIterator version 0.033
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
DESCRIPTION¶
The Attean::ListIterator class represents a typed iterator. It conforms to the Attean::API::RepeatableIterator role.
The Attean::ListIterator constructor requires two named arguments:
METHODS¶
- "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.
- "size"
- Returns the number of elements still remaining in the iterator until it is fully consumed or until "reset" is called.
