Shareable

In document Application Programming Interface (Page 116-121)

Declaration

public interface Shareable

Description

The Shareable interface serves to identify all shared objects. Any object that needs to be shared through the applet firewall must directly or indirectly implement this interface. Only those methods specified in a shareable interface are available through the firewall. Implementation classes can implement any number of shareable interfaces and can extend other shareable implementation classes.

Declaration

javacard.framework

SystemException

Declaration

public class SystemException extends CardRuntimeException java.lang.Object | +--java.lang.Throwable | +--java.lang.Exception | +--java.lang.RuntimeException | +--javacard.framework.CardRuntimeException | +--javacard.framework.SystemException

Description

SystemException represents aJCSystem class related exception. It is also thrown by thejavacard. framework.Applet.register() methods and by theAID class constructor.

These API classes throw Java Card runtime environment-owned instances ofSystemException. Java Card runtime environment-owned instances of exception classes are temporary Java Card runtime environment Entry Point Objects and can be accessed from any applet context. References to these temporary objects cannot be stored in class variables or instance variables or array components. See Runtime Environment

Specification for the Java Card Platform, section 6.2.1 for details.

Member Summary

Fields

static short ILLEGAL_AID

This reason code is used by thejavacard.framework.Applet.register()

method to indicate that the input AID parameter is not a legal AID value.

static short ILLEGAL_TRANSIENT

This reason code is used to indicate that the request to create a transient object is not allowed in the current applet context.

static short ILLEGAL_USE

This reason code is used to indicate that the requested function is not allowed.

static short ILLEGAL_VALUE

This reason code is used to indicate that one or more input parameters is out of allowed bounds.

static short NO_RESOURCE

This reason code is used to indicate that there is insufficient resource in the Card for the request.

static short NO_TRANSIENT_SPACE

This reason code is used by themakeTransient..() methods to indicate that no room is available in volatile memory for the requested object.

Inherited Member Summary

Fields

ILLEGAL_VALUE

Declaration:

public static final short ILLEGAL_VALUE

Description:

This reason code is used to indicate that one or more input parameters is out of allowed bounds.

NO_TRANSIENT_SPACE

Declaration:

public static final short NO_TRANSIENT_SPACE

Description:

This reason code is used by themakeTransient..() methods to indicate that no room is available in volatile memory for the requested object.

ILLEGAL_TRANSIENT

Declaration:

public static final short ILLEGAL_TRANSIENT

Description:

This reason code is used to indicate that the request to create a transient object is not allowed in the current applet context. See Runtime Environment Specification for the Java Card Platform, section 6.2.1 for details.

Constructors

SystemException(short reason)

with the specified reason.

ILLEGAL_AID

ILLEGAL_AID

Declaration:

public static final short ILLEGAL_AID

Description:

This reason code is used by thejavacard.framework.Applet.register() method to indicate that the input AID parameter is not a legal AID value.

NO_RESOURCE

Declaration:

public static final short NO_RESOURCE

Description:

This reason code is used to indicate that there is insufficient resource in the Card for the request.

For example, the Java Card Virtual Machine maythrow this exception reason when there is insufficient heap space to create a new instance.

ILLEGAL_USE

Declaration:

public static final short ILLEGAL_USE

Description:

This reason code is used to indicate that the requested function is not allowed. For example,JCSystem. requestObjectDeletion() method throws this exception if the object deletion mechanism is not implemented.

Constructors

SystemException(short)

Declaration:

public SystemException(short reason)

Description:

Constructs a SystemException. To conserve on resources usethrowIt() to use the Java Card runtime environment-owned instance of this class.

Parameters:

reason - the reason for the exception

Methods

throwIt(short)

Declaration:

public static void throwIt(short reason) throws SystemException

throwIt(short)

Description:

Throws the Java Card runtime environment-owned instance ofSystemException with the specified reason.

Java Card runtime environment-owned instances of exception classes are temporary Java Card runtime environment Entry Point Objects and can be accessed from any applet context. References to these temporary objects cannot be stored in class variables or instance variables or array components. See

Runtime Environment Specification for the Java Card Platform, section 6.2.1 for details.

Parameters:

reason - the reason for the exception

TransactionException

Declaration

public class TransactionException extends CardRuntimeException java.lang.Object | +--java.lang.Throwable | +--java.lang.Exception | +--java.lang.RuntimeException | +--javacard.framework.CardRuntimeException | +--javacard.framework.TransactionException

Description

TransactionExceptionrepresents an exception in the transaction subsystem. The methods referred to in this class are in theJCSystem class.

TheJCSystem class and the transaction facility throw Java Card runtime environment-owned instances of

TransactionException.

Java Card runtime environment-owned instances of exception classes are temporary Java Card runtime environment Entry Point Objects and can be accessed from any applet context. References to these temporary objects cannot be stored in class variables or instance variables or array components. See Runtime Environment
