NAME ^

Reflex::Connector - non-blocking client socket connector

VERSION ^

This document describes version 0.099, released on April 21, 2013.

SYNOPSIS ^

This is a partial excerpt from eg/eg-38-promise-client.pl

        use Reflex::Connector;
        use Reflex::Stream;

        my $connector = Reflex::Connector->new(port => 12345);

        my $event = $connector->next();
        if ($event->{name} eq "failure") {
                die("error $event->{arg}{errnum}: $event->{arg}{errstr}");
        }

        my $stream = Reflex::Stream->new(
                handle => $event->{arg}{socket},
        );

DESCRIPTION ^

Reflex::Connector asynchronously establishes a client connection. It is almost entirely implemented in Reflex::Role::Connecting. That role's documentation contains important details that won't be covered here.

Public Attributes

address

address defines the remote address to which Reflex::Connector will attempt a connection. It defaults to "127.0.0.1". See Reflex::Role::Connecting for more details.

port

port defines the remote port to which Reflex::Connector will attempt a connection. It has no default. See Reflex::Role::Connecting for more details.

socket

Reflex::Connector will provide its own socket by default. It also accepts a socket that may be configured in custom ways.

See connector in Reflex::Role::Connecting for more details.

Public Methods

None.

Callbacks

on_connection

on_connection is called when Reflex::Connector establishes a connection. Reflex::Role::Connecting explains the data returned with on_connection. If necessary, that role will also define a default on_connection handler that emits "success" event. (TODO - Does this make sense?)

on_error

on_error is called whenever a connection fails for some reason. returns an error. Reflex::Role::Connecting explains the data returned with on_error. If necessary, that role will also define a default on_error handler that emits an "error" event.

Public Events

Reflex::Connector emits events related to establishing clinet connections. These events are defined by Reflex::Role::Connecting, and they will be explained there.

success

If no on_connection handler is set, then Reflex::Connector will emit a "success" event if the connection is successfuly established. Reflex::Role::Connecting explains this event in more detail.

error

If no on_error handler is set, then Reflex::Connector will emit an "error" event whenever a connection fails to establish. Reflex::Role::Connecting explains this event in more detail.

EXAMPLES ^

The SYNOPSIS is a partial excerpt from eg/eg-38-promise-client.pl

eg/eg-35-tcp-client.pl is a more callbacky client.
