          java.lang.Exception

    @TransactionType(value=NOT_SUPPORTED)
    public class APDUException

extends CardRuntimeException

`APDUException` represents an `APDU` related exception.

Direct instances of this exception class are not bound to any context and can be passed between contexts without any restrictions. Objects created and returned by the methods of this class are owned by the caller. In particular, a call to the `Throwable.toString()` returns a String instance bound to the owner context of the caller.

See Runtime Environment Specification for the Java Card Platform, Connected Edition, chapter 7 for details regarding transfer of ownership.

Field Summary
`static short` | `BAD_LENGTH` This reason code is used by the `APDU.setOutgoingLength()` method to indicate `APDUException.BAD_LENGTH` if `len` is negative, or greater than 256 and the currently selected applet does not implement the `javacardx.apdu.ExtendedLength` interface, 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.

Constructor Summary
`APDUException(short reason)` Constructs an APDUException.

Method Summary
`static void` | `throwIt(short reason)` Deprecated. Deprecated for extended applets and web applications on the Connected Edition of the Java Card 3 Platform. Use constructor instead.

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.

  See Also:
    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.

  See Also:
    Constant Field Values

### BAD_LENGTH

    public static final short BAD_LENGTH

  This reason code is used by the `APDU.setOutgoingLength()` method to indicate
  - `APDUException.BAD_LENGTH` if `len` is negative, or greater than 256 and the currently selected applet does not implement the `javacardx.apdu.ExtendedLength` interface, or if non BLOCK CHAINED data transfer is requested and `len` is greater than (IFSD-2), where IFSD is the Outgoing Block Size. The -2 accounts for the status bytes in T=1.

    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.

  See Also:
    Constant Field Values

Constructor Detail

### APDUException

    public APDUException(short reason)

  Constructs an APDUException.

  Parameters:
    `reason` - the reason for the exception.

Method Detail

### throwIt

    public static void throwIt(short reason)

  Deprecated. Deprecated for extended applets and web applications on the Connected Edition of the Java Card 3 Platform. Use constructor instead.

  Throws a new instance of `APDUException` with the specified reason.

  Note that a new instance is thrown upon each call to this method.

  This method is for backward compatibility with Java Card 2.x and for interoperability of classic applet applications with the Java Card 3 Classic edition.

  Parameters:
    `reason` - the reason for the exception
  Throws:
    `APDUException` - always
