NAME

6       "IO::Async::Protocol::LineStream" - stream-based protocols using lines
7       of text
8

SYNOPSIS

10       Most likely this class will be subclassed to implement a particular
11       network protocol.
12
13        package Net::Async::HelloWorld;
14
15        use strict;
16        use warnings;
17        use base qw( IO::Async::Protocol::LineStream );
18
19        sub on_read_line
20        {
21           my $self = shift;
22           my ( $line ) = @_;
23
24           if( $line =~ m/^HELLO (.*)/ ) {
25              my $name = $1;
26
27              $self->invoke_event( on_hello => $name );
28           }
29        }
30
31        sub send_hello
32        {
33           my $self = shift;
34           my ( $name ) = @_;
35
36           $self->write_line( "HELLO $name" );
37        }
38
39       This small example elides such details as error handling, which a real
40       protocol implementation would be likely to contain.

DESCRIPTION

EVENTS

44       The following events are invoked, either using subclass methods or CODE
45       references in parameters:
46
47   on_read_line $line
48       Invoked when a new complete line of input is received.
49

PARAMETERS

51       The following named parameters may be passed to "new" or "configure":
52
53   on_read_line => CODE
54       CODE reference for the "on_read_line" event.
55

METHODS

57   write_line
58          $lineprotocol->write_line( $text )
59
60       Writes a line of text to the transport stream. The text will have the
61       end-of-line marker appended to it; $text should not end with it.
