Class DynamicAddressChannel

java.lang.Object
  org.jivesoftware.wildfire.mediaproxy.DynamicAddressChannel

All Implemented Interfaces:

Runnable, DatagramListener

public class DynamicAddressChannel
extends Object
implements Runnable, DatagramListener

Listen packets from defined dataSocket and send packets to the defined host. But also provides a mechanism to dynamic bind host and port implementing DatagramListener methods to change the host and port values according to the received packets.
