Package javacard.framework

package javacard.framework

Provides a framework of classes and interfaces for building, communicating with and working with Java Card technology-based applets. These classes and interfaces provide the minimum required functionality for a Java Card environment. If additional functionality is desired, for example to specialize the card for a particular market, other frameworks would need to be added.

The key classes and interfaces in this package are:

  • AID-encapsulates the Application Identifier (AID) associated with an applet.
  • APDU-provides methods for controlling card input and output.
  • Applet-the base class for all Java Card technology-based applets on the card. It provides methods for working with applets to be loaded onto, installed into and executed on a Java Card technology-compliant smart card.
  • CardException, CardRuntimeException-provide functionality similar to java.lang.Exception and java.lang.RuntimeException in the standard Java programming language, but specialized for the card environment.
  • ISO7816-provides important constants for working with input and output data.
  • JCSystem-provides methods for controlling system functions such as transaction management, transient objects, object deletion mechanism, resource management, and inter-applet object sharing.
  • MultiSelectable-provides methods that support advanced programming techniques with logical channels.
  • Shareable-provides a mechanism that lets objects that implement this interface be shared across an applet firewall.
  • Util-provides convenient methods for working with arrays and array data.

    Description
    AID
    This class encapsulates the Application Identifier (AID) associated with an applet.
    APDU
    Application Protocol Data Unit (APDU) is the communication format between the card and the off-card applications.
    APDUException
    APDUException represents an APDU related exception.
    Applet
    This abstract class defines an Java Card technology-based applet.
    AppletEvent
    The AppletEvent interface provides a callback interface for the Java Card runtime environment to inform the applet about life cycle events.
    CardException
    The CardException class defines a field reason and two accessor methods getReason() and setReason().
    CardRuntimeException
    The CardRuntimeException class defines a field reason and two accessor methods getReason() and setReason().
    ISO7816
    ISO7816 encapsulates constants related to ISO 7816-3 and ISO 7816-4.
    ISOException
    ISOException class encapsulates an ISO 7816-4 response status word as its reason code.
    JCSystem
    The JCSystem class includes a collection of methods to control applet execution, resource management, atomic transaction management, object deletion mechanism and inter-applet object sharing in the Java Card environment.
    MultiSelectable
    The MultiSelectable interface identifies the implementing Applet subclass as being capable of concurrent selections.
    OwnerPIN
    This class represents an Owner PIN, implements Personal Identification Number functionality as defined in the PIN interface, and provides the ability to update the PIN and thus owner functionality.
    OwnerPINBuilder
    The OwnerPINBuilder class is factory for Owner PIN objects.
    OwnerPINx
    The OwnerPINx interface represents an Owner PIN, extends Personal Identification Number functionality as defined in the PIN interface, and provides the ability to update the PIN, update the try limit and try counter and thus owner functionality.
    OwnerPINxWithPredecrement
    The OwnerPINxWithPredecrement interface represents an Owner PIN, extends Personal Identification Number functionality as defined in the PIN interface, and provides the ability to update the PIN, update the try limit and try counter and thus owner functionality.
    PIN
    This interface represents a PIN.
    PINException
    PINException represents a OwnerPIN class or OwnerPINx -implementing class access-related exception.
    Resources
    An instance of Resources provides means to read the resources accessible to the caller code.
    SensitiveArrays
    The SensitiveArrays class provides methods for creating and handling integrity-sensitive array objects.
    Shareable
    The Shareable interface serves to identify all shared objects.
    SystemException
    SystemException represents a JCSystem class related exception.
    TransactionException
    TransactionException represents an exception in the transaction subsystem.
    UserException
    UserException represents a User exception.
    Util
    The Util class contains common utility functions.
