DESCRIPTION

This client class provides seemless connection and authentication within the legacy jabber:component:accept namespace.

EVENTS AND METHODS

new()

Accepts many arguments:

IP

The IP address in dotted quad, or the FQDN for the server

PORT

The remote port of the server to connect.

HOSTNAME

The hostname of the server. Used in addressing.

PASSWORD

The password to be used in handshake authentication (SHA-1)

ALIAS

The alias the component should register for use within POE. Defaults to the class name.

STATE_PARENT

The alias or session id of the session you want the component to contact.

STATES

A hashref containing the event names the component should fire upon finishing initialization and receiving input from the server.

INITFINISH, INPUTEVENT, and ERROREVENT must be defined.

INITFINISH is fired after connection setup, TLS and SASL negotiation, and resource binding and session establishment take place.

ARG0 in INITFINISH will be your jid as a string. ARG0 in INPUTEVENT will be the payload as a POE::Filter::XML::Node. ARG0 in ERROREVENT will be a POE::Component::Jabber::Error

See POE::Component::Jabber::Error for possible error types and constants.

See POE::Filter::XML and its accompanying documentation to properly manipulate incoming data in your INPUTEVENT, and creation of outbound data.

DEBUG

If bool true, will enable debugging and tracing within the component. All XML sent or received through the component will be printed to STDERR

EVENTS

'output_handler'

This is the event that you use to push data over the wire. Accepts either raw XML or POE::Filter::XML::Nodes.

'return_to_sender'

This event takes (1) a POE::Filter::XML::Node and gives it a unique id, and (2) a return event and places it in the state machine. Upon receipt of response to the request, the return event is fired with the response packet.

'shutdown_socket'

One argument, time in seconds to call shutdown on the underlying Client::TCP

'reconnect_to_server'

This event can take (1) the ip address of a new server and (2) the port. This event may also be called without any arguments and it will force the component to reconnect.

NOTES AND BUGS

This is a connection broker. This should not be considered a first class client. All upper level functions are the responsibility of the end developer.

return_to_sender() no longer overwrites end developer supplied id attributes. Instead, it now checks for a collision, warning and replacing the id, if there is a collision.
