NAME

6       Parallel::Pipes::App - friendly interface for Parallel::Pipes
7

SYNOPSIS

9         use Parallel::Pipes::App;
10
11         my @result = Parallel::Pipes::App->map(
12           num => 3,
13           work => sub { my $task = shift; $task * 2 },
14           tasks => [1, 2, 3, 4, 5],
15         );
16         # @result is ( 2, 4, 6, 8, 10 )
17

DESCRIPTION

19       Parallel::Pipes::App provides friendly interfaces for Parallel::Pipes.
20

METHODS

22       Parallel::Pipes::App provides 2 class method:
23
24   map
25         my @result = Parallel::Pipes::App->map(
26           num => $num,
27           work => $work,
28           tasks => \@task,
29         );
30
31       Process @task by $work in $num pre-forked child processes, and get
32       @result.  This is almost the same as
33
34         my @result = map { $work->($_) } @task;
35
36       except that $work is executed in a child process, not in the current
37       process.
38
39   run
40         Parallel::Pipes::App->run(
41           num => $num,
42           work => $work,
43           tasks => \@task,
44           before_work => $before_work,
45           after_work => $after_work,
46         );
47
48       "run" is a more generic form of "map". In fact, we can write "map" by
49       using "run":
50
51         my @result;
52         Parallel::Pipes::App->run(
53           num => $num,
54           work => $work,
55           tasks => \@task,
56           before_work => sub {},
57           after_work => sub { push @result, $_[0] },
58         );
