Class Session


  • public class Session
    extends java.lang.Object
    Session - supplementary class for MAPPER demonstration
    According to Martin Fowler the mapper can't be invoked directly by either of the two components it is connected to, because they both don't even know of the mapper.
    One solution is a third party driving the mapper. In this example a session is responsible for this task.
