Class SharedSender

java.lang.Object

com.yahoo.feedapi.SharedSender

All Implemented Interfaces:

com.yahoo.messagebus.ReplyHandler

public class SharedSender
extends Object
implements com.yahoo.messagebus.ReplyHandler

This class allows multiple clients to use one shared messagebus session. The user should create a ResultCallback, which acts as a "session" for that client, and send one or more messages using the send() methods. When done sending messages, the client can wait for all messages to be replied to using the waitForPending method.
