POE::Wheel::Null(3) User Contributed Perl Documentation POE::Wheel::Null(3)NAMEPOE::Wheel::Null - POE Wheel that does put()s data nowhere, and sends
nothing.
SYNOPSIS
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.
DESCRIPTIONPOE::Wheel::Null creates a wheel which doesn't do anything upon put(),
and doesn't send any events to the current session.
PUBLIC METHODS
