7       of values
8

VERSION

11

SYNOPSIS

13         use v5.14;
14         use Attean;
15         my @values = map { Attean::Literal->new($_) } (1,2,3);
16         my $iter = Attean::ListIterator->new(
17           values => \@values,
18           item_type => 'Attean::API::Term',
19         );
20
21         say $iter->next->value; # 1
22         say $iter->next->value; # 2
23         say $iter->next->value; # 3

DESCRIPTION

26       The Attean::ListIterator class represents a typed iterator.  It
27       conforms to the Attean::API::RepeatableIterator role.
28
29       The Attean::ListIterator constructor requires two named arguments:
30
31       values
32           An array reference containing the items to iterate over.
33
34       item_type
35           A string representing the type of the items that will be returned
36           from the iterator.
37

METHODS

39       "reset"
40           Resets the iterator's internal state so that iteration begins again
41           at the beginning of the values array.
42
43       "next"
44           Returns the iterator's next item, or undef upon reaching the end of
45           iteration.
46
47       "size"
48           Returns the number of elements still remaining in the iterator
49           until it is fully consumed or until "reset" is called.
