org.xmlBlaster.test.client
Class TestFailSafe

java.lang.Object
  junit.framework.Assert
      junit.framework.TestCase
          org.xmlBlaster.test.client.TestFailSafe

All Implemented Interfaces:

junit.framework.Test, I_ConnectionStateListener

public class TestFailSafe
extends junit.framework.TestCase
implements I_ConnectionStateListener

Tests the fail safe behavior of the I_XmlBlasterAccess client helper class (does not test server side fail safe).
For a description of what this fail save mode can do for you, please read the API documentation of I_XmlBlasterAccess.

This is an interesting example, since it creates a XmlBlaster server instance in the same JVM , but in a separate thread, talking over CORBA with it.

Invoke examples:

   java junit.textui.TestRunner -noloading org.xmlBlaster.test.client.TestFailSafe
   java junit.swingui.TestRunner -noloading org.xmlBlaster.test.client.TestFailSafe

TEST:

reachedAliveSync

public void reachedAliveSync(ConnectionStateEnum oldState,
                             I_XmlBlasterAccess connection)

This is the callback method invoked from I_XmlBlasterAccess informing the client in an asynchronous mode if the connection was established.

This method is enforced through interface I_ConnectionStateListener

Specified by:

reachedAliveSync in interface I_ConnectionStateListener

Parameters:

oldState - is always ALIVE.

reachedAlive

public void reachedAlive(ConnectionStateEnum oldState,
                         I_XmlBlasterAccess connection)

Description copied from interface: I_ConnectionStateListener

This is the callback method invoked from XmlBlasterAccess notifying the client that a connection has been established and that its status is now ALIVE.

Note that this method is invoked also when the connection has been established the first time. In this case the connection is fully operational but your connect() call has not yet returned. You can access the returned connect QoS in this case with connect.getConnectReturnQos().

You can erase all entries of the queue manually or add others before you return and in this way control the behavior. During you have control in reachedAlive() the client side queue is blocked and does not accept publish or request messages from other threads. So you can do peacefully your work (your thread is allowed to modify the queue exclusively).

If you send messages during this method invocation they are queued only and are sent as soon as this method returns.

This method is invoked by the login polling thread from I_XmlBlasterAccess in which case it is a physical Alive, and by the connect method on successful login in which case it is a logical Alive.

Specified by:

reachedAlive in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

reachedPolling

public void reachedPolling(ConnectionStateEnum oldState,
                           I_XmlBlasterAccess connection)

Description copied from interface: I_ConnectionStateListener

This is the callback method invoked from XmlBlasterAccess informing the client that the connection state has changed to POLLING.

Specified by:

reachedPolling in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

reachedDead

public void reachedDead(ConnectionStateEnum oldState,
                        I_XmlBlasterAccess connection)

Description copied from interface: I_ConnectionStateListener

This is the callback method invoked from XmlBlasterAccess informing the client that the connection was lost (i.e. when the state of the connection has gone to DEAD).

Specified by:

reachedDead in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

main

public static void main(java.lang.String[] args)

Deprecated. Use the TestRunner from the testsuite to run it:

   java -Djava.compiler= junit.textui.TestRunner org.xmlBlaster.test.client.TestFailSafe

Invoke: java org.xmlBlaster.test.client.TestFailSafe
