DESCRIPTION
This module provides a helper abstraction for handling out of band data
as specified in XEP-0066.
The object that is generated handles out of band data requests to and
from others.
There is are also some utility function defined to get for example the
oob info from an XML element:
FUNCTIONS
url_from_node ($node)
This function extracts the URL and optionally a description field
from the XML element in $node (which must be a
AnyEvent::XMPP::Node).
$node must be the XML node which contains the <url> and optionally
<desc> element (which is eg. a <x xmlns='jabber:x:oob'> element)!
(This method searches both, the jabber:x:oob and jabber:iq:oob
namespaces for the <url> and <desc> elements).
It returns a hash reference which should have following structure:
{
url => "http://someurl.org/mycoolparty.jpg",
desc => "That was a party!",
}
If nothing was found this method returns nothing (undef).
METHODS
new ()
This is the constructor, it takes no further arguments.
reply_success ($con, $node)
This method replies to the sender of the oob that the URL was
retrieved successfully.
$con and $node are the $con and $node arguments of the "oob_recv"
event you want to reply to.
reply_failure ($con, $node, $type)
This method replies to the sender that either the transfer was
rejected or it was not fount.
If the transfer was rejectes you have to set $type to 'reject',
otherwise $type must be 'not-found'.
$con and $node are the $con and $node arguments of the "oob_recv"
event you want to reply to.
send_url ($con, $jid, $url, $desc, $cb)
This method sends a out of band file transfer request to $jid.
$url is the URL that the otherone has to download. $desc is an
optional description string (human readable) for the file pointed
at by the url and can be undef when you don't want to transmit any
description.
$cb is a callback that will be called once the transfer is
successful.
The first argument to the callback will either be undef in case of
success or 'reject' when the other side rejected the file or
'not-found' if the other side was unable to download the file.
EVENTS
These events can be registered to whith "reg_cb":
oob_recv => $con, $node, $url
This event is generated whenever someone wants to send you a out of
band data file. $url is a hash reference like it's returned by
"url_from_node".
$con is the AnyEvent::XMPP::Connection (Or
AnyEvent::XMPP::IM::Connection) the data was received from.
$node is the AnyEvent::XMPP::Node of the IQ request, you can get
the senders JID from the 'from' attribute of it.
If you fetched the file successfully you have to call
"reply_success". If you want to reject the file or couldn't get it
call "reply_failure".
