Detailed Description

Factory class for creating applet messages.

The factory class offers a service to create applet messages of the correct type. The applet message type is passed as a parameter to the create() function and the function constructs and returns a correct message object. If an invalid message type is requested, the factory returns NULL.

Note:

The creator() function is static so you don't need an instance of the factory. Actually you can't even create instances of it since the constructor is hidden.
