Allows applications using a channel in a pull mode to receive a state from another channel instance providing state. Channels have to be configured with STREAMING_STATE_TRANSFER protocol rather than the default STATE_TRANSFER protocol in order to receive this event.

The following code demonstrate how to pull events from a channel, processing StreamingSetStateEvent and retrieving hypothetical state in the form of LinkedList from event's InputStream reference.

 Object obj=channel.receive(0);
 if(obj instanceof StreamingSetStateEvent) {
 StreamingSetStateEvent evt=(StreamingSetStateEvent)obj;
 ObjectInputStream ois = null;   	
 try {			
 ois = new ObjectInputStream(evt.getArg());
 state = (LinkedList)ois.readObject();  
 } catch (Exception e) {} 
 finally
 {
 try {				
 ois.close();
 } catch (IOException e) {
 System.err.println(e);
 }
 }                
 }
