NAME ^

POE::Component::Supervisor::Supervised::Proc - A supervision descriptor for UNIX processes.

SYNOPSIS ^

    use POE;

    use POE::Component::Supervisor;
    use POE::Component::Supervisor::Supervised::Proc;

    POE::Component::Supervisor->new(
        children => [
            POE::Component::Supervisor::Supervised::Proc->new(
                program => [qw(memcached -m 64)],
                restart_policy => "permanent",
            ),
        ],
    );

    $poe_kernel->run;

DESCRIPTION ^

This is a factory object that creates POE::Component::Supervisor::Handle::Proc objects.

ATTRIBUTES ^

See also "ATTRIBUTES" in POE::Component::Supervisor::Handle::Proc, all of the documented attributes that apply to handle creation are borrowed by this class.

handle_class

The class to instantiate.

Defaults to POE::Component::Supervisor::Handle::Proc.

Note that attributes are inherited only from POE::Component::Supervisor::Handle::Proc. If your handle class requires additional attributes, you must subclass your own Supervised variant.

The _inherit_attributes_from_handle_class method can then be invoked on your subclass to reinherit all the attributes. Read the source of POE::Component::Supervisor::Supervised for more details.

METHODS ^

See also "METHODS" in POE::Component::Supervisor::Supervised.

spawn

Called by POE::Component::Supervisor when a new instance of the child process should be spawned.

is_abnormal_exit

Used by should_restart. See POE::Component::Supervisor::Supervised for details.

Returns true if the exit_code argument is not equal to 0.
