NAME

Reflex::Role::InStreaming - add streaming input behavior to a class

VERSION

version 0.088

SYNOPSIS

        use Moose;

        has socket => ( is => 'rw', isa => 'FileHandle', required => 1 );

        with 'Reflex::Role::InStreaming' => {
                handle    => 'socket',
                cb_data   => 'on_socket_data',    # default
                cb_error  => 'on_socket_error',   # default
                cb_closed => 'on_socket_closed',  # default
        };

        sub on_socket_data {
                my ($self, $arg) = @_;
                print "Socket received data: $arg->{data}\n";
        }

        sub on_socket_error {
                my ($self, $arg) = @_;
                print "$arg->{errfun} error $arg->{errnum}: $arg->{errstr}\n";
                $self->stopped();
        }

        sub on_socket_closed {
                my $self = shift;
                print "Connection closed.\n";
                $self->stopped();
        }

DESCRIPTION

Reflex::Role::InStreaming is a Moose parameterized role that adds streaming input behavior to Reflex-based classes. It comprises Reflex::Role::Collectible for dynamic composition, Reflex::Role::Readable for asynchronous input watching, and Reflex::Role::Reading to perform input.

See Reflex::Stream if you prefer runtime composition with objects, or you just find Moose syntax difficult to handle.

Required Role Parameters

handle

The handle parameter must contain the name of the attribute that holds a filehandle from which data will be read. The name indirection allows the role to generate methods that are unique to the handle. For example, a handle named "XYZ" would generate these methods by default:

        cb_closed   => "on_XYZ_closed",
        cb_data     => "on_XYZ_data",
        cb_error    => "on_XYZ_error",
        method_stop => "stop_XYZ",

This naming convention allows the role to be used for more than one handle in the same class. Each handle will have its own name, and the mixed in methods associated with them will also be unique.

Optional Role Parameters

cb_closed

Please see "cb_closed" in Reflex::Role::Reading. Reflex::Role::Reading's "cb_closed" defines this callback.

cb_data

Please see "cb_data" in Reflex::Role::Reading. Reflex::Role::Reading's "cb_data" defines this callback.

cb_error

Please see "cb_error" in Reflex::Role::Reading. Reflex::Role::Reading's "cb_error" defines this callback.

method_stop

Please see "method_stop" in Reflex::Role::Readable. Reflex::Role::Readable's "method_stop" defines this method.

EXAMPLES

See eg/RunnerRole.pm in the distribution.
