NAME

Top

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

SYNOPSIS

Top

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.

DESCRIPTION

Top

POE::Wheel::Null creates a wheel which doesn't do anything upon put(), and doesn't send any events to the current session.

PUBLIC METHODS

Top

The new() method creates a new null wheel.

ID

Returns the wheel unique ID

put
