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 re-inherit all the attributes. Read the source of POE::Component::Supervisor::Supervised for more details.

METHODS

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

spawn

is_abnormal_exit

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