Detailed Description

This client connects to xmlBlaster and subscribes to a message.

We then publish the message and receive it asynchronous in the update() method.

Note that the CORBA layer is transparently hidden, and all code conforms to STD C++ (with STL).

 Invoke: HelloWorld2

bool HelloWorld2::reachedAlive	(	StatesEnum	oldState,
		I_ConnectionsHandler *	connectionsHandler
	)			[virtual]

This is the callback method invoked from org::xmlBlaster::util::dispatch::ConnectionsHandler notifying the client that a connection has been established and that its status is now ALIVE.

It has a bool return which informs the org::xmlBlaster::util::dispatch::ConnectionsHandler what to do with the entries in the queue. If you return 'true', then the queue is flushed (i.e. the contents of the queue are sent to xmlBlaster). If you return 'false', then the contents of the queue are left untouched. You can then erase all entries manually. Note that this method is invoked also when the connection has been established the first time.

Implements org::xmlBlaster::client::I_ConnectionProblems.

void HelloWorld2::reachedDead	(	StatesEnum	oldState,
		I_ConnectionsHandler *	connectionsHandler
	)			[virtual]

This is the callback method invoked from org::xmlBlaster::util::dispatch::ConnectionsHandler informing the client that the connection was lost (i.e.

when the state of the connectionsHandler has gone to DEAD).
