SYNOPSIS

   use Net::XMPP2::Ext::Disco;

   my $con = Net::XMPP2::IM::Connection->new (...);
   $con->add_extension (my $disco = Net::XMPP2::Ext::Disco->new);
   $disco->request_items ($con, 'romeo@montague.net', undef,
      sub {
         my ($disco, $items, $error) = @_;
         if ($error) { print "ERROR:" . $error->string . "\n" }
         else {
            ... do something with the $items ...
         }
      }
   );

DESCRIPTION

It also allows you to setup a disco-info/items tree that others can walk and also lets you publish disco information.

This class is derived from Net::XMPP2::Ext and can be added as extension to objects that implement the Net::XMPP2::Extendable interface or derive from it.

METHODS

new (%args)

Creates a new disco handle.

set_identity ($category, $type, $name)

This sets the identity of the top info node.

$name is optional and can be undef. Please note that $name will overwrite all previous set names! If $name is undefined then no previous set name is overwritten.

For a list of valid identites look at:

   http://www.xmpp.org/registrar/disco-categories.html
    

Valid identity $types for "$category = "client"" may be:

   bot
   console
   handheld
   pc
   phone
   web
    

unset_identity ($category, $type)

This function removes the identity $category and $type.

enable_feature ($uri)

This method enables the feature $uri, where $uri should be one of the values from the Name column on:

   http://www.xmpp.org/registrar/disco-features.html
    

These features are enabled by default:

   http://jabber.org/protocol/disco#info
   http://jabber.org/protocol/disco#items
    

You can pass also a list of features you want to enable to "enable_feature"!

disable_feature ($uri)

This method enables the feature $uri, where $uri should be one of the values from the Name column on:

   http://www.xmpp.org/registrar/disco-features.html
    

You can pass also a list of features you want to disable to "disable_feature"!

request_items ($con, $dest, $node, $cb)

This method does send a items request to the JID entity $from. $node is the optional node to send the request to, which can be undef.

$con must be an instance of Net::XMPP2::Connection or a subclass of it. The callback $cb will be called when the request returns with 3 arguments: the disco handle, an Net::XMPP2::Ext::Disco::Items object (or undef) and an Net::XMPP2::Error::IQ object when an error occured and no items were received.

The timeout of the request is the IQ timeout of the connection $con.

   $disco->request_items ($con, 'a@b.com', undef, sub {
      my ($disco, $items, $error) = @_;
      die $error->string if $error;

      # do something with the items here ;_)
   });
    

request_info ($con, $dest, $node, $cb)

This method does send a info request to the JID entity $from. $node is the optional node to send the request to, which can be undef.

$con must be an instance of Net::XMPP2::Connection or a subclass of it. The callback $cb will be called when the request returns with 3 arguments: the disco handle, an Net::XMPP2::Ext::Disco::Info object (or undef) and an Net::XMPP2::Error::IQ object when an error occured and no items were received.

The timeout of the request is the IQ timeout of the connection $con.

   $disco->request_info ($con, 'a@b.com', undef, sub {
      my ($disco, $info, $error) = @_;
      die $error->string if $error;

      # do something with info here ;_)
   });
