@TransactionType(value=NOT_SUPPORTED) public class BioException
The BioException
class encapsulates specific exceptions which
can be thrown by the methods of the javacardx.biometry
package
in case of error.
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.
