TAP::Parser::Iterator::Array - Iterator for array-based TAP sources

Version 3.50

=head1 SYNOPSIS
  use TAP::Parser::Iterator::Array;
  my @data = ('foo', 'bar', baz');
  my $it   = TAP::Parser::Iterator::Array->new(\@data);
  my $line = $it->next;
=head1 DESCRIPTION
This is a simple iterator wrapper for arrays of scalar content, used by
L<TAP::Parser>.  Unless you're writing a plugin or subclassing, you probably
won't need to use this module directly.
=head1 METHODS
=head2 Class Methods
=head3 C<new>
Create an iterator.  Takes one argument: an C<$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.
