=head1 NAME
TAP::Parser::Iterator::Stream - Iterator for filehandle-based TAP sources
=head1 VERSION
Version 3.42
=cut
our $VERSION = '3.42';
=head1 SYNOPSIS
use TAP::Parser::Iterator::Stream;
open( TEST, 'test.tap' );
my $it = TAP::Parser::Iterator::Stream->new(\*TEST);
my $line = $it->next;
=head1 DESCRIPTION
This is a simple iterator wrapper for reading from filehandles, 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. Expects one argument containing a filehandle.
=cut
# new() implementation supplied by TAP::Object
sub _initialize {
my ( $self, $thing ) = @_;
$self->{fh} = $thing;
return $self;
}
=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. Always returns zero.
=head3 C<exit>
Get the exit status for this iterator. Always returns zero.

sub wait { shift->exit }
sub exit { shift->{fh} ? () : 0 }
sub next_raw {
my $self = shift;
my $fh = $self->{fh};

}

return;
}
}
sub _finish {
my $self = shift;
close delete $self->{fh};
}
sub get_select_handles {
my $self = shift;
# return our handle in case it's a socket or pipe (select()-able)
return ( $self->{fh}, )
if (-S $self->{fh} || -p $self->{fh});
return;
