=head1 NAME
TAP::Parser::Iterator::Array - Internal TAP::Parser array Iterator
=head1 VERSION
Version 3.17
=cut
$VERSION = '3.17';
=head1 SYNOPSIS
# see TAP::Parser::IteratorFactory for preferred usage
# to use directly:
use TAP::Parser::Iterator::Array;
my @data = ('foo', 'bar', baz');
my $it = TAP::Parser::Iterator::Array->new(\@data);
my $line = $it->next;
=head1 DESCRIPTION
This is a simple iterator wrapper for arrays of scalar content, used by
L<TAP::Parser>. Unless you're subclassing, you probably won't need to use
this module directly.
=head1 METHODS
=head2 Class Methods
=head3 C<new>
Create an iterator. Takes one argument: an C<$array_ref>
=head2 Instance Methods
=head3 C<next>
Iterate through it, of course.
=head3 C<next_raw>
Iterate raw input without applying any fixes for quirky input syntax.
=head3 C<wait>
Get the wait status for this iterator. For an array iterator this will always
be zero.
=head3 C<exit>
Get the exit status for this iterator. For an array iterator this will always
be zero.
