Attean::CodeIterator - Iterator implementation backed by a generator function
This document describes Attean::CodeIterator version 0.001_01
use v5.14; use Attean; my $iter = Attean::CodeIterator->new( generator => sub { state $value = 0; Attean::Literal->new(++$value) }, item_type => 'Attean::API::Term', ); say $iter->next->value; # 1 say $iter->next->value; # 2 say $iter->next->value; # 3
The Attean::CodeIterator class represents a typed iterator. It conforms to the Attean::API::Iterator role.
The Attean::CodeIterator constructor requires two named arguments:
A code reference that when called will return either the iterator's next item, or undef upon reaching the end of iteration.
A Type::Tiny object representing the type of the items that will be returned from the iterator.
next
Returns the iterator's next item, or undef upon reaching the end of iteration.
