SYNOPSIS

        use POE::Component::Client::Telnet;

        my $poco = POE::Component::Client::Telnet->new(
                alias => 'telnet',                # optional; You can use $poco->session_id() instead
                debug => 1,                       # optional; 1 to turn on debugging
                options => { trace => 1 },        # optional; Options passed to the internal session
                package => 'Net::Telnet::Cisco',  # optional; Allows use of other Net::Telnet
                telnet_options => [ ],            # optional; Options passed to Net::Telnet->new()
        );

        # Start your POE session, then...

        $kernel->post('telnet' => open => { event => 'result' },"rainmaker.wunderground.com");

        sub result {
                my ($kernel,$ref) = @_[KERNEL,ARG0];

                if ( $ref->{result} ) {
                        print "connected: $ref->{result}\n";
                } else {
                        print STDERR join(' ', @{ $ref->{error} ) . "\n";
                }
        }

DESCRIPTION

Consult the Net::Telnet documentation for more details.

METHODS

new

Takes a number of arguments, all of which are optional. 'alias', the kernel alias to bless the component with; 'debug', set this to 1 to see component debug information; 'options', a hashref of POE::Session options that are passed to the component's session creator; 'telnet_options', an optional array ref of options that will be passed to Net::Telnet->new(); 'package', an optional package name that is a base of Net::Telnet, like Net::Telnet::Cisco.

session_id

Takes no arguments, returns the POE::Session ID of the component. Useful if you don't want to use aliases.

yield

This method provides an alternative object based means of posting events to the component. First argument is the event to post, following arguments are sent as arguments to the resultant post.

  $poco->yield( open => { event => 'result' }, "localhost" );
    

call

This method provides an alternative object based means of calling events to the component. First argument is the event to call, following arguments are sent as arguments to the resultant call.

  $poco->call( open => { event => 'result' }, "localhost" );
    

(all other Net::Telnet methods

All Net::Telnet methods can be called, but the first param must be the options hash as noted below in the INPUT section below.

For example:

        $poco->open( { event => 'opened' },"localhost" );
    

One exception, the 'option_callback' method accepts an event name instead of a code ref. If called with no params, 'result' will be the event currently set. Also, when the callback is fired, 'result' will be an array ref of $option, $is_remote, $is_enabled, $was_enabled, $buf_position. See the 'option_callback' method of Net::Telnet for details.

INPUT

It is possible to pass arbitary data in the request hashref that could be used in the resultant event handler. Simply define additional key/value pairs of your own. It is recommended that one prefixes keys with '_' to avoid future clashes.

OUTPUT

The hashref will contain keys for 'state', and 'result'. 'state' is the operation that was requested, 'result' is what the function returned.

result

This is data returned from the function you called. Usually a scalar, but can be an array ref when using 'option_callback'.

error

In the event of an error occurring this will be defined. It is an scalar which contains the error.
