javacard.framework.CardException
@TransactionType(value=NOT_SUPPORTED) 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.
Even if a transaction is in progress, the update of the internal
reason
field shall not participate in the transaction.
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.
