Class ClientSubDispatch

java.lang.Object
  javaclients.ClientSubDispatch

All Implemented Interfaces:

I_Callback

public class ClientSubDispatch
extends java.lang.Object
implements I_Callback

This client demonstrates the method subscribe() with a later publish().

We use a subscribe variant, where for every subscribe we define a specialized update method.
Like this not all callback messages arrive in a centralized update() with the need to look into them and decide why the arrived.

This demo uses the I_XmlBlasterAccess helper class, which hides the raw CORBA/RMI/XMLRPC nastiness and allows this client side dispatching.
Invoke examples:

    java -cp ../../lib/xmlBlaster.jar javaclients.ClientSubDispatch

    java javaclients.ClientSubDispatch -loginName Jeff -dispatch/connection/protocol RMI

    java javaclients.ClientSubDispatch -help

Method Detail

update

public java.lang.String update(java.lang.String cbSessionId,
                               UpdateKey updateKey,
                               byte[] content,
                               UpdateQos updateQos)

This is the callback method invoked from xmlBlaster delivering us a new asynchronous message.

Specified by:

update in interface I_Callback

Parameters:

cbSessionId - The session ID specified by the client which registered the callback. You can specify a cbSessionId during connection (with ConnectQos) and this is bounced back here so you can authenticate the message.

updateKey - The arrived key containing the topic name

content - The arrived message content. This is your payload.
