public class APDUException
extends CardRuntimeException

APDUException represents an APDU related exception.

The APDU class throws Java Card runtime environment-owned instances of APDUException.

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 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 NO_T0_REISSUE
          This reason code indicates that during T=0 protocol, the CAD did not reissue the same APDU command with the corrected length in response to a <6Cxx> response status to request command reissue with the specified length.
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.

Constant Field Values

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.

Constant Field Values

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.

See Also:
Constant Field Values

IO_ERROR

public static final short IO_ERROR
This reason code indicates that an unrecoverable error occurred in the I/O transmission layer.

See Also:
Constant Field Values

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 Applet.process() method.

See Also:
Constant Field Values

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 Applet.process() method.

See Also:
Constant Field Values

NO_T0_REISSUE

public static final short NO_T0_REISSUE
This reason code indicates that during T=0 protocol, the CAD did not reissue the same APDU command with the corrected length in response to a <6Cxx> response status to request command reissue with the specified length. The outgoing transfer has been aborted. No more data or status can be sent to the CAD in this Applet.process() method

Constructor Detail

APDUException

public APDUException(short reason)
Constructs an APDUException. 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 APDUException
Throws the Java Card runtime environment-owned instance of APDUException 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:
APDUException - always
