13
14           my $mux = TAP::Parser::Multiplexer->new;
15           $mux->add( $parser1, $stash1 );
16           $mux->add( $parser2, $stash2 );
17           while ( my ( $parser, $stash, $result ) = $mux->next ) {
18               # do stuff
19           }

DESCRIPTION

22       "TAP::Parser::Multiplexer" gathers input from multiple TAP::Parsers.
23       Internally it calls select on the input file handles for those parsers
24       to wait for one or more of them to have input available.
25
26       See TAP::Harness for an example of its use.

METHODS

29   Class Methods
30       "new"
31
32           my $mux = TAP::Parser::Multiplexer->new;
33
34       Returns a new "TAP::Parser::Multiplexer" object.
35
36   Instance Methods
37       "add"
38
39         $mux->add( $parser, $stash );
40
41       Add a TAP::Parser to the multiplexer. $stash is an optional opaque
42       reference that will be returned from "next" along with the parser and
43       the next result.
44
45       "parsers"
46
47         my $count   = $mux->parsers;
48
49       Returns the number of parsers. Parsers are removed from the multiplexer
50       when their input is exhausted.
51
52       "next"
53
54       Return a result from the next available parser. Returns a list
55       containing the parser from which the result came, the stash that
56       corresponds with that parser and the result.
57
58           my ( $parser, $stash, $result ) = $mux->next;
59
60       If $result is undefined the corresponding parser has reached the end of
61       its input (and will automatically be removed from the multiplexer).
62
63       When all parsers are exhausted an empty list will be returned.
64
65           if ( my ( $parser, $stash, $result ) = $mux->next ) {
66               if ( ! defined $result ) {
67                   # End of this parser
68               }
69               else {
70                   # Process result
71               }
72           }
73           else {
74               # All parsers finished
75           }
