    my $str = <IN>;
    # ...
    close IN;
    $job->finish();
    
    # or...
    
    my $data = $job->get_data();
    $job->finish();

DESCRIPTION

DATA

    print "email: ", $job->{metadata}->{submitter_email}, "\n";

Otherwise, you can access the queued data file using "get_data_path()", or directly as a string using "get_data()".

METHODS

$data = $job->get_data();

Return the job's data. The return value will be a string, the data that was originally enqueued for this job.

$path = $job->get_data_path();

Return the full path to the task's data file. This can be opened and read safely while the job is active.

$nbytes = $job->get_data_size_bytes();

Retrieve the size of the data without performing a "stat" operation.

$secs = $job->get_time_submitted_secs();

Get the seconds-since-epoch (in other words, the "time_t") on the submitting host when this task was submitted.

$usecs = $job->get_time_submitted_usecs();

Get the microseconds within that second, as measured by "gettimeofday" on the submitting host, when this task was submitted.

$hostname = $job->get_hostname_submitted();

Get the name of the submitting host where this task originated.

$job->touch_active_lock();

Update the lockfile to reflect that this task is still being processed. If a task has been active, but the lockfile has not been touched for more than 600 seconds, another "IPC::DirQueue" queue processor may take it over.

$job->finish();

Report that the job has been completed, and may be removed from the queue.

$job->return_to_queue();

Return the job to the queue, unfinished. Another task processor may then pick it up.
