java.lang.Object java.lang.Throwable java.lang.Exception javacard.framework.CardException
public class CardException
The CardException
class
defines a field reason
and two accessor methods
getReason()
and setReason()
. The reason
field encapsulates an exception cause identifier in the Java Card platform.
All Java Card platform checked Exception classes should extend
CardException
. This class also provides a resource-saving mechanism
(throwIt()
method) for using a Java Card runtime environment-owned instance of this class.
Even if a transaction is in progress, the update of the internal reason
field shall not participate in the transaction. The value of the internal reason
field of Java Card runtime environment-owned instance is reset to 0 on a tear or reset.

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.
