Class SystemException


public class SystemExceptionextends 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. TheseAPIclasses throw Java Card runtime environment-owned instances of SystemException.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.

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_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 the makeTransient..() methodsto indicate that no room is available in volatile memory for the requested object.

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.

See Also:Constant Field Values


NO_TRANSIENT_SPACE

public static final short NO_TRANSIENT_SPACE

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

See Also:Constant Field Values


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

See Also:Constant Field Values


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.

See Also:Constant Field Values


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.

See Also:Constant Field Values


ILLEGAL_USE

public static final short ILLEGAL_USE

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.

Constructor Detail

SystemException

public SystemException(short reason)

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

Parameters:reason - the reason for the exception

Method Detail

throwIt

public static void throwIt(short reason) throws SystemException

Throws the Java Card runtime environment-owned instance of SystemException 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

Throws: SystemException- always
