io::async::detachedcode
IO::Async::DetachedCode(3pm) User Contributed Perl Documentation IO::Async::DetachedCode(3pm)NAME
"IO::Async::DetachedCode" - execute code asynchronously in child processes
SYNOPSIS
This object is used indirectly via the "IO::Async::Loop"'s "detach_code" method.
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $code = $loop->detach_code(
code => sub {
my ( $number ) = @_;
return is_prime( $number );
}
);
$code->call(
args => [ 123454321 ],
on_return => sub {
my $isprime = shift;
print "123454321 " . ( $isprime ? "is" : "is not" ) . " a prime number
";
},
on_error => sub {
print STDERR "Cannot determine if it's prime - $_[0]
";
},
);
$loop->run;
DESCRIPTION
This object class provides a legacy compatibility layer for existing code that tries to construct such an object. It should not be used for
new code; see instead the IO::Async::Function object, for which this is now a wrapper.
CONSTRUCTOR
$code = $loop->detach_code( %params )
This function returns a new instance of a "IO::Async::DetachedCode" object. The %params hash takes the following keys:
code => CODE
A block of code to call in the child process.
stream
marshaller
These arguments are no longer used; any values passed will be ignored.
workers => INT
Optional integer, specifies the number of parallel workers to create.
If not supplied, 1 is used.
exit_on_die => BOOL
setup => ARRAY
Passed through to the underlying "IO::Async::Function" object.
METHODS
$code->call( %params )
Calls one invocation of the contained function code block. See the "call" method on "IO::Async::Function" for more detail.
$code->shutdown
This method requests that the detached worker processes stop running.
$n_workers = $code->workers
This method in scalar context returns the number of workers currently running.
@worker_pids = $code->workers
This method in list context returns a list of the PID numbers of all the currently running worker processes.
