public class APDUException

extends CardRuntimeException

APDUException represents an APDU related exception.

The APDU class throws JCRE owned instances of APDUException.

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	BAD_LENGTH This reason code is used by the APDU.setOutgoingLength() method to indicate that the length parameter is greater that 256 or if non BLOCK CHAINED data transfer is requested and len is greater than (IFSD-2), where IFSD is the Outgoing Block Size.
static short	BUFFER_BOUNDS This reason code is used by the APDU.sendBytes() method to indicate that the sum of buffer offset parameter and the byte length parameter exceeds the APDU buffer size.
static short	ILLEGAL_USE This APDUException reason code indicates that the method should not be invoked based on the current state of the APDU.
static short	IO_ERROR This reason code indicates that an unrecoverable error occurred in the I/O transmission layer.
static short	NO_T0_GETRESPONSE This reason code indicates that during T=0 protocol, the CAD did not return a GET RESPONSE command in response to a <61xx> response status to send additional data.
static short	T1_IFD_ABORT This reason code indicates that during T=1 protocol, the CAD returned an ABORT S-Block command and aborted the data transfer.

Field Detail

ILLEGAL_USE

public static final short ILLEGAL_USE

This APDUException reason code indicates that the method should not be invoked based on the current state of the APDU.

BUFFER_BOUNDS

public static final short BUFFER_BOUNDS

This reason code is used by the APDU.sendBytes() method to indicate that the sum of buffer offset parameter and the byte length parameter exceeds the APDU buffer size.

BAD_LENGTH

public static final short BAD_LENGTH

This reason code is used by the APDU.setOutgoingLength() method to indicate that the length parameter is greater that 256 or if non BLOCK CHAINED data transfer is requested and len is greater than (IFSD-2), where IFSD is the Outgoing Block Size.

IO_ERROR

public static final short IO_ERROR

This reason code indicates that an unrecoverable error occurred in the I/O transmission layer.

NO_T0_GETRESPONSE

public static final short NO_T0_GETRESPONSE

This reason code indicates that during T=0 protocol, the CAD did not return a GET RESPONSE command in response to a <61xx> response status to send additional data. The outgoing transfer has been aborted. No more data or status can be sent to the CAD in this APDU.process() method.

T1_IFD_ABORT

public static final short T1_IFD_ABORT

This reason code indicates that during T=1 protocol, the CAD returned an ABORT S-Block command and aborted the data transfer. The incoming or outgoing transfer has been aborted. No more data can be received from the CAD. No more data or status can be sent to the CAD in this APDU.process() method.

Constructor Detail

APDUException

public APDUException(short reason)

Constructs an APDUException. 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 APDUException 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:

APDUException - always.
