NAME

6       POE::Wheel::Null - POE Wheel that does put()s data nowhere, and sends
7       nothing.
8

SYNOPSIS

10       As a primary use whenever you would normally...
11
12        delete $heap->{wheel};
13
14       or something equivalent, instead do...
15
16        $heap->{wheel} = POE::Wheel::Null->new();
17
18       to prevent calls to $heap->{wheel} from causing runtime errors in perl.
19       This seems to be a Good Idea (tm) when working with long running
20       programs in the traditional POE way.
21
