# A Helper for XEP-0080 User Location
#
# Use this helper to send a user's location, or receive them from a
# specified jid. Described at http://www.xmpp.org/extensions/xep-0080.html
#
# For example:
# <pre>
# h = UserLocation::Helper( @client, 'radio1@hug.hellomatty.com' )
# h.add_userlocation_callback do |location|
# puts "Now in: #{location.locality}"
# end
# </pre>
class Helper < PubSub::ServiceHelper
##
# Send out the current location.
#
# location:: [Jabber::UserLocation::Location] current_location
def current_location(location)
item = Jabber::PubSub::Item.new()
item.add(location)
publish_item_to(NS_USERLOCATION, item)
end
##
# Use this method to indicate that you wish to stop publishing
# a location.
def stop_publishing
current_location(Jabber::UserLocation::Location.new())
end
##
# Add a callback that will be invoked when a location is received
# from the jid specified when you constructed the Helper.
def add_userlocation_callback(prio = 200, ref = nil, &block)
