public class SystemException

extends CardRuntimeException

SystemException represents a JCSystem class related exception. It is also thrown by the javacard.framework.Applet.register() methods and by the AID class constructor.

These API classes throw JCRE owned instances of SystemException.

JCRE owned instances of exception classes are temporary JCRE 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 Java Card Runtime Environment (JCRE) 2.1 Specification for details.

Field Summary

static short	ILLEGAL_AID This reason code is used by the javacard.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_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 the makeTransient..() methods to indicate that no room is available in volatile memory for the requested object.

Constructor Summary

SystemException(short reason)
Constructs a SystemException.

Field Detail

ILLEGAL_VALUE

public static final short ILLEGAL_VALUE

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

NO_TRANSIENT_SPACE

public static final short NO_TRANSIENT_SPACE

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

ILLEGAL_TRANSIENT

public static final 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. See Java Card Runtime Environment (JCRE) 2.1 Specification for details.

ILLEGAL_AID

public static final short ILLEGAL_AID

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

NO_RESOURCE

public static final short NO_RESOURCE

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 may throw this exception reason when there is insufficient heap space to create a new instance.

Constructor Detail

SystemException

public SystemException(short reason)

Constructs a SystemException. To conserve on resources use throwIt() to use the JCRE owned instance of this class.

Parameters:

reason - the reason for the exception.

Method Detail

throwIt

public static void throwIt(short reason)

Throws the JCRE owned instance of SystemException with the specified reason.

JCRE owned instances of exception classes are temporary JCRE 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 Java Card Runtime Environment (JCRE) 2.1 Specification for details.

Parameters:

reason - the reason for the exception.

Throws:

SystemException - always.
