POE::Wheel::Null - POE Wheel that does put()s data nowhere, and sends nothing.
As a primary use whenever you would normally...
delete $heap->{wheel};
or something equivalent, instead do...
$heap->{wheel} = POE::Wheel::Null->new();
to prevent calls to $heap->{wheel} from causing runtime errors in perl. This seems to be a Good Idea (tm) when working with long running programs in the traditional POE way.
POE::Wheel::Null creates a wheel which doesn't do anything upon put(), and doesn't send any events to the current session.
The new() method creates a new null wheel.
Returns the wheel unique ID
Does nothing (intended)
None
POE::Wheel, POE
Roughly zero.
