Detailed Description

This is a little helper class wraps the CORBA BlasterCallback update(), and delivers the client a nicer update() method.

Member Function Documentation

virtual std::string org::xmlBlaster::client::I_Callback::update	(	std::string &	sessionId,
		org::xmlBlaster::client::key::UpdateKey &	updateKey,
		unsigned char *	content,
		long	contentSize,
		org::xmlBlaster::client::qos::UpdateQos &	updateQos
	)			[pure virtual]

This is the callback method invoked from CorbaConnection informing the client in an asynchronous mode about a new message.

The raw BlasterCallback.update() is unpacked and for each arrived message this update is called.

So you should implement in your client the I_Callback interface - suppling the update() method where you can do with the message whatever you want.

If you do multiple logins with the same I_Callback implementation, the loginName which is delivered with this update() method may be used to dispatch the message to the correct client.

Parameters:

	sessionId	The sessionId to authenticate the callback This sessionId was passed on subscription we can use it to decide if we trust this update()
	updateKey	The arrived key
	content	The arrived message content. If the size is 0 it is NULL
	contentSize	the size of the content of the message
	qos	Quality of Service of the org::xmlBlaster::util::MessageUnit

Returns:

The status std::string

Implemented in org::xmlBlaster::client::XmlBlasterAccess.
