NAME

AnyEvent::XMPP::Ext::Disco - Service discovery manager class for XEP-0030

SYNOPSIS

    use AnyEvent::XMPP::Ext::Disco;
 
    my $con = AnyEvent::XMPP::IM::Connection->new (...);
    $con->add_extension (my $disco = AnyEvent::XMPP::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

This module represents a service discovery manager class. You make instances of this class and get a handle to send discovery requests like described in XEP-0030.

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 AnyEvent::XMPP::Ext and can be added as extension to objects that implement the AnyEvent::XMPP::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 AnyEvent::XMPP::Connection or a subclass of it. The callback $cb will be called when the request returns with 3 arguments: the disco handle, an AnyEvent::XMPP::Ext::Disco::Items object (or undef) and an AnyEvent::XMPP::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 AnyEvent::XMPP::Connection or a subclass of it. The callback $cb will be called when the request returns with 3 arguments: the disco handle, an AnyEvent::XMPP::Ext::Disco::Info object (or undef) and an AnyEvent::XMPP::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 ;_)
    });
