Is it possible to flush the contents of a POE::Wheel::FollowTail wheel?

What I'd like to be able to do before closing is somthing like:

sub finish_file {
  my $heap = $_[HEAP];


  # do other stuff here
}

I am using one to monitor a file that is left with a non '\n' terminated line at when the process that creates it is finished. $heap->{wheel}->flush; # this should generate an InputEvent with any dangling bits left in the buffer.

sub finish_file {
  my $heap = $_[HEAP];
  $heap->{wheel}->set_filter( POE::Filter::Stream->new() );
  # ...
}

If Wheel::FollowTail had a set_filter() method, you could use it to switch to POE::Filter::Stream. That would get you a final InputEvent with whatever remained in the buffer. On your end, the code would be: I've attached an untested patch for set_filter(). Let me know if it works, and I'll commit it.
