The use case seems to treat 0xfefefefe as a record separator. In this
case, I would use POE::Filter::Line->new(Literal => "\xfe\xfe\xfe\xfe").
How do you guarantee you have a complete record without some kind of
length prefix or terminator? Running out of octets in $data doesn't
guarantee that it ended on a record boundary.

Being lazy, I was hoping I could just define a different filter for
POE::Wheel::FollowTail, that instead of being line oriented, would
be record oriented (each record begins with 0xfefefefe).
I currently have a binary parser that can parse the data. Assuming
the binary data is slurped up into the scalar "$data", the following
code works great:
while($data) {
# Find next beginning-of-record flag & extract record...
$data =~ s/^[^\xfe]*(\xfe\xfe\xfe\xfe[^\xfe]+)// || die "No luck";
my $event=$1;
# Send record to parser...
$parser->parse( $event );
# Print restult...
print "events DUMP:\n", Dumper($parser->{events}), "\n";
}
Being very new to POE and filters, is there something already
existing that I could use? I've toyed with modifying one of the
following:
POE::Filter::RecordBlock
POE::Filter::Regexp
POE::Filter::Block
Do any of these make sense for what I want to do? Should I punt on
using FollowTail and try something else?
Any advice is appreciated!
Thanks
