Class CardException
Direct Known Subclasses: UserException
public class CardExceptionextends Exception
The CardException class defines a field reason and two accessor methodsgetReason() 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.
