IO::Async::Protocol::LineStream(3pm)

Usage

Most likely this class will be subclassed to implement a particular network protocol.

   package Net::Async::HelloWorld;
   use strict;
   use warnings;
   use base qw( IO::Async::Protocol::LineStream );
   sub on_read_line
   {
      my $self = shift;
      my ( $line ) = @_;
      if( $line =~ m/^HELLO (.*)/ ) {
         my $name = $1;
         $self->invoke_event( on_hello => $name );
      }
   }
   sub send_hello
   {
      my $self = shift;
      my ( $name ) = @_;
      $self->write_line( "HELLO $name" );
   }

This small example elides such details as error handling, which a real protocol implementation would be likely to contain.

Overview

Events

The following events are invoked, either using subclass methods or CODE references in parameters:

on_read_line $line

Invoked when a new complete line of input is received.

Parameters

The following named parameters may be passed to "new" or "configure":

on_read_line => CODE

CODE reference for the "on_read_line" event.

Methods

write_line

   $lineprotocol->write_line( $text );

Writes a line of text to the transport stream. The text will have the end-of-line marker appended to it; $text should not end with it.

Releases

7 releases since Debian 7 (Wheezy); the text changed 6 times.
