Class APDUException

  • 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, Java Card Platform, Classic Edition, section 6.2.1 for details.

    • Field Summary

      Fields 
      Modifier and Type Field Description
      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.

      • 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
        • 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.

      • IO_ERROR

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

        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.

        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.

        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 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, Java Card Platform, Classic Edition, section 6.2.1 for details.

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