Method: Jabber::Roster::Helper#add_subscription_request_callback

Defined in:
lib/vendor/xmpp4r/lib/xmpp4r/roster/helper/roster.rb

#add_subscription_request_callback(prio = 0, ref = nil, &block) ⇒ Object

Add a callback for subscription requests, which will be called upon receiving a <presence type='subscribe'/> stanza

The block receives two objects:

  • the Jabber::Roster::Helper::RosterItem (or nil)

  • the <presence/> stanza

Response to this event can be taken with accept_subscription and decline_subscription.

Example usage:

my_roster.add_subscription_request_callback do |item,presence|
  if accept_subscription_requests
    my_roster.accept_subscription(presence.from)
  else
    my_roster.decline_subscription(presence.from)
  end
end
