public abstract class AppletProxy
extends BasicAppletCardService

AppletProxy is the base class for all applet proxies. This class is derived from the class BasicAppletCardService. It adds an attribute that holds the application identifier of the applet to which the applet proxy is associated. It provides methods similar to those of the base class, except that the application identifier parameter is not necessary because every AppletProxy knows the AID of the applet associated with it.
