smartcard.CardConnection: The CardConnection abstract class manages connections with a card
and apdu transmission.
smartcard.CardConnectionDecorator: The CardConnectionDecorator is a Decorator around the
CardConnection abstract class, and allows dynamic addition of
features to the CardConnection, e.g.
smartcard.CardConnectionEvent: The CardConnectionEvent is sent to CardConnectionObserver objects
when a CardConnection event occurs.
smartcard.ClassLoader: ClassLoader allows you to load modules from packages without
hard-coding their class names in code; instead, they might be
specified in a configuration file, as command-line parameters, or
within an interface.
