NAME

       "IO::Async::Protocol::LineStream" - stream-based protocols using lines of text

SYNOPSIS

       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.

DESCRIPTION

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.
