NAME

Net::XMPP2::Ext - Extension baseclass and documentation

DESCRIPTION

This module has documentation about the supported extensions and also is a base class for all extensions that can be added via the add_extension method of the classes that derive from Net::XMPP2::Extendable. (That are: Net::XMPP2::Client, Net::XMPP2::Connection and Net::XMPP2::IM::Connection)

Basically add_extension makes the extension an event receiver for all events that the extended object receives.

Supportet extensions

This is the list of supported XMPP extensions:

XEP-0004 - Data Forms (Version 2.8)

This extension handles data forms as described in XEP-0004. Net::XMPP2::Ext::DataForm allows you to construct, receive and answer data forms. This is neccessary for all sorts of things in XMPP. For example XEP-0055 (Jabber Search) or also In-band registration.

XEP-0030 - Service Discovery (Version 2.3)

This extension allows you to send service discovery requests and define a set of discoverable information. See also Net::XMPP2::Ext::Disco.

XEP-0066 - Out of Band Data (Version 1.5)

This extension allows to receive and send out of band data URLs and provides helperfunctions to handle jabber:x:oob data. See also Net::XMPP2::Ext::OOB.

XEP-0077 - In-Band Registration (Version 2.2)

This extension lets you register new accounts "in-band". For details please take a look at Net::XMPP2::Ext::Registration.

XEP-0078 - Non-SASL Authentication (Version 2.3)

After lots of sweat and curses I implemented finally iq auth. Unfortunately the XEP-0078 specifies things that are not implemented, in fact the only server that worked was openfire and psyced.org.

So I de-analized the iq auth and now it just barfs the IQ set out on the stream with the username and the password.

If you insist on XEP-0078 behaviour enable the anal_iq_auth option when creating the stream.

You can also completly disable iq auth, well, just see the documentation of Net::XMPP2::Connection

XEP-0082 - XMPP Date and Time Profiles (Version 1.0)

Implemented some functions to deal with XMPP timestamps, see Net::XMPP2::Util to_xmpp_time, to_xmpp_datetime, from_xmpp_datetime.

They are meant as simple formatters for you, you will still need to handle timezone stuff and such yourself.

XEP-0086 - Error Condition Mappings (Version 1.0)

"A mapping to enable legacy entities to correctly handle errors from XMPP-aware entities."

This extension will enable sending of the old error codes when generating a stanza error with for example the write_error_tag method of Net::XMPP2::Writer.

Also if only the old numeric codes are supplied the Net::XMPP2::Error::Stanza class tries to map the numeric codes to the new error conditions if possible.

XEP-0091 - Delayed Delivery (Version 1.3)

See also XEP-0203 below.

XEP-0092 - Software Version (Version 1.1)

The ability to answer to software version, name and operating system requests and being able to send such requests is implemented in Net::XMPP2::Ext::Version.

XEP-0114 - Jabber Component Protocol (Version 1.5)

This extension allows you to connect to a server as a component and makes it possible to implement services like pubsub, muc, or whatever you can imagine (even gateways). See documentation of Net::XMPP2::Component and the example samples/simple_component.

XEP-0199 - XMPP Ping (Version 1.0)

You can send ping requests to other entities and also are able to reply to them. On top of that the Net::XMPP2::Ext::Ping extension implements a connection timeout mechanism based on this.

XEP-0203 - Delayed Delivery (Version 1.0)

Both delayed delivery XEPs are supported and are implemented by Net::XMPP2::IM::Delayed which is a super class of Net::XMPP2::IM::Message and Net::XMPP2::IM::Presence.

If you need to fetch delay from stanzas you caught yourself in an event you can use a Net::XMPP2::IM::Delayed object to parse/fetch the delay out of the Net::XMPP2::Node.

Use the functions described above in the XEP-0082 item to decode the timestamps of delays.
