NAME

AnyEvent::ProcessPool::Pipeline - A simplified, straightforward way to parallelize tasks

VERSION

version 0.02

SYNOPSIS

  use AnyEvent::ProcessPool::Pipeline;

  pipeline workers => 4,
    in {
      get_next_task();
    },
    out {
      process_result(shift->recv);
    };

EXPORTED SUBROUTINES

pipeline

in

out

Launches an AnyEvent::ProcessPool and immediately starts processing tasks it receives when executing the code specified by in. As results arrive (and not necessarily in the order in which they were queued), they are delivered as condition variables (ready ones, guaranteed not to block) via the code supplied by out. The pipeline will continue to run until in returns undef, after which it will continue to run until all pending results have been delivered. pipeline returns the total number of tasks processed.

Aside from in and out, all other arguments are passed unchanged to AnyEvent::ProcessPool's constructor.
