Package org.jivesoftware.openfire

Class MulticastRouter

java.lang.Object
org.jivesoftware.openfire.container.BasicModule
org.jivesoftware.openfire.MulticastRouter
All Implemented Interfaces:
Module, ServerFeaturesProvider, org.xmpp.component.IQResultListener
public class MulticastRouter extends BasicModule implements ServerFeaturesProvider, org.xmpp.component.IQResultListener
Router of packets with multiple recipients. Clients may send a single packet with multiple recipients and the server will broadcast the packet to the target receipients. If recipients belong to remote servers, then this server will discover if remote target servers support multicast service. If a remote server supports the multicast service, a single packet will be sent to the remote server. If a remote server doesn't the support multicast processing, the local server sends a copy of the original stanza to each address.

The current implementation will only search up to the first level of nodes of remote servers when trying to find out if remote servers have support for multicast service. It is assumed that it is highly unlikely for servers to have a node in the second or third depth level providing the multicast service. Servers should normally provide this service themselves or at least as a first level node. This is an implementation of JEP-0033: Extended Stanza Addressing

  • Method Details

    • route

      public void route(org.xmpp.packet.Packet packet)

    • receivedAnswer

      public void receivedAnswer(org.xmpp.packet.IQ packet)
      Specified by:
      receivedAnswer in interface org.xmpp.component.IQResultListener

    • answerTimeout

      public void answerTimeout(String packetId)
      Specified by:
      answerTimeout in interface org.xmpp.component.IQResultListener

    • getFeatures

      public Iterator<String> getFeatures()
      Description copied from interface: ServerFeaturesProvider
      Returns an Iterator (of String) with the supported features by the server. The features to include are the features offered and supported protocols by the SERVER. The idea is that different modules may provide their features that will ultimately be part of the features offered by the server.
      Specified by:
      getFeatures in interface ServerFeaturesProvider
      Returns:
      an Iterator (of String) with the supported features by the server.

    • initialize

      public void initialize(XMPPServer server)
      Description copied from class: BasicModule

      Initializes the basic module.

      Inheriting classes that choose to override this method MUST call this initialize() method before accessing BasicModule resources.

      Specified by:
      initialize in interface Module
      Overrides:
      initialize in class BasicModule
      Parameters:
      server - the server hosting this module.
