26
27  use TAP::Parser::Source;
28  use TAP::Parser::SourceHandler::RawTAP;
29
30  my $source = TAP::Parser::Source->new->raw( \"1..1\nok 1\n" );

32
33  my $class = 'TAP::Parser::SourceHandler::RawTAP';

37=head1 DESCRIPTION
38
39This is a I<raw TAP output> L<TAP::Parser::SourceHandler> - it has 2 jobs:
40
411. Figure out if the L<TAP::Parser::Source> it's given is raw TAP output
42(L</can_handle>).
43
442. Creates an iterator for raw TAP output (L</make_iterator>).
45
46Unless you're writing a plugin or subclassing L<TAP::Parser>, you probably
47won't need to use this module directly.

54
55  my $vote = $class->can_handle( $source );
56
57Only votes if $source is an array, or a scalar with newlines.  Casts the
58following votes:
59
60  0.9  if it's a scalar with '..' in it
61  0.7  if it's a scalar with 'ok' in it
62  0.3  if it's just a scalar with newlines
63  0.5  if it's an array

85
86  my $iterator = $class->make_iterator( $source );
87
88Returns a new L<TAP::Parser::Iterator::Array> for the source.
89C<$source-E<gt>raw> must be an array ref, or a scalar ref.
