I have a question concerning the proper usage of POE::Filter::Reference.
I wish to use POE::Filter::Reference to send data from a child process to
a parent process across stdout (using POE::Wheel::Run).
Would this be accomplished by:
a) in the child process, use POE::Filter::Reference to serialize the data
structure, then use a print to stdout to send it, picking it up in my main
processes handler for stdout..
or
b) use it like a standard poe filter... ie...
$heap->{wheel} = POE::Wheel::Run->new(
Program => sub { &test($argument) },
StdoutEvent => 'stdout',
StderrEvent => 'stderr',
StdinFilter => POE::Filter::Line->new(),
StdoutFilter => POE::Filter::Line->new(),
StderrFilter => POE::Filter::Reference->new()
);
to me, the second example doesn't make sense because from the man page,
using POE::Filter::Reference seems like a manual process (ie, you use
->put and ->get to serialize and deserialize).
However, the syntax of POE::Filter::Foo makes it seem as if you can use
this filter on any io stream the same way you would POE::Filter::Line,
POE::Filter::Stream, POE::Filter::HTTPD, etc.
?
I'm confused :)
