Net::Jabber::Component - Jabber Component Library
Net::Jabber::Component is a module that provides a developer easy access to developing server components in the Jabber Instant Messaging protocol.
Component.pm seeks to provide enough high level APIs and automation of the low level APIs that writing a Jabber Component in Perl is trivial. For those that wish to work with the low level you can do that too, but those functions are covered in the documentation for each module.
Net::Jabber::Component provides functions to connect to a Jabber server, login, send and receive messages, operate as a server side component, and disconnect. You can use all or none of the functions, there is no requirement.
For more information on how the details for how Net::Jabber is written please see the help for Net::Jabber itself.
For a full list of high level functions available please see Net::Jabber::Protocol and Net::XMPP::Protocol.
use Net::Jabber;
$Con = new Net::Jabber::Component();
$Con->Execute(hostname=>"jabber.org",
componentname=>"service.jabber.org",
secret=>"XXXX"
);
#
# For the list of available functions see Net::XMPP::Protocol.
#
$Con->Disconnect();
new(debuglevel=>0|1|2, - creates the Component object. debugfile
debugfile=>string, should be set to the path for the debug
debugtime=>0|1) log to be written. If set to "stdout"
then the debug will go there. debuglevel
controls the amount of debug. For more
information about the valid setting for
debuglevel, debugfile, and debugtime see
Net::Jabber::Debug.
AuthSend(secret=>string) - Perform the handshake and authenticate
with the server.
Connect(hostname=>string, - opens a connection to the server
port=>integer, based on the value of
componentname=>string, connectiontype. The only valid
connectiontype=>string) setting is:
accept - TCP/IP remote connection
In the future this might be used
again by offering new features.
If accept then it connects to the
server listed in the hostname
value, on the port listed. The
defaults for the two are localhost
and 5269.
Note: A change from previous
versions is that Component now
shares its core with Client. To
that end, the secret should no
longer be used. Call AuthSend
after connecting. Better yet,
use Execute.
Connected() - returns 1 if the Component is connected to the server,
and 0 if not.
Disconnect() - closes the connection to the server.
Execute(hostname=>string, - Generic inner loop to handle
port=>int, connecting to the server, calling
secret=>string, Process, and reconnecting if the
componentname=>string, connection is lost. There are four
connectiontype=>string, callbacks available that are called
connectattempts=>int, at various places in the loop.
connectsleep=>int) onconnect - when the component
connects to the
server.
onauth - when the component has
completed its handshake
with the server this
will be called.
onprocess - this is the most
inner loop and so
gets called the most.
Be very very careful
what you put here
since it can
*DRASTICALLY* affect
performance.
ondisconnect - when connection is
lost.
onexit - when the function gives
up trying to connect and
exits.
The arguments are passed straight
on to the Connect function, except
for connectattempts and
connectsleep. connectattempts is
the number of time that the
Component should try to connect
before giving up. -1 means try
forever. The default is -1.
connectsleep is the number of
seconds to sleep between each
connection attempt.
Process(integer) - takes the timeout period as an argument. If no
timeout is listed then the function blocks until
a packet is received. Otherwise it waits that
number of seconds and then exits so your program
can continue doing useful things. NOTE: This is
important for GUIs. You need to leave time to
process GUI commands even if you are waiting for
packets. The following are the possible return
values, and what they mean:
1 - Status ok, data received.
0 - Status ok, no data received.
undef - Status not ok, stop processing.
IMPORTANT: You need to check the output of every
Process. If you get an undef then the connection
died and you should behave accordingly.
