=head1 NAME
TAP::Parser::Iterator::Stream - Internal TAP::Parser 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::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 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.
=cut
sub wait { shift->exit }
sub exit { shift->{fh} ? () : 0 }
sub next_raw {
my $self = shift;
my $fh = $self->{fh};
if ( defined( my $line = <$fh> ) ) {
chomp $line;
return $line;
}
else {
$self->_finish;
return;
}
}
sub _finish {
my $self = shift;
close delete $self->{fh};
