## javacardx.biometry
Class BioException

    java.lang.Object
      java.lang.Throwable
          java.lang.Exception
              java.lang.RuntimeException
                  javacard.framework.CardRuntimeException

    @TransactionType(value=NOT_SUPPORTED)
    public class BioException

extends CardRuntimeException

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.

Since:
  2.2.2

Field Summary
`static short` | `ILLEGAL_USE` This reason code is used to indicate that the method should not be invoked based on the current state of the card.
`static short` | `ILLEGAL_VALUE` This reason code is used to indicate that one or more input parameters is out of allowed bounds.
`static short` | `INVALID_DATA` This reason code is used to indicate that the data the system encountered is illegible.
`static short` | `NO_SUCH_BIO_TEMPLATE` This reason code is used to indicate that the provided bio template type is not supported by the template builder.
`static short` | `NO_TEMPLATES_ENROLLED` This reason code is used to indicate that no reference template is available for matching, or that the reference template is uninitialized.

Constructor Summary
`BioException(short reason)` Construct a new biometric exception using a provided reason code.

Method Summary
`static void` | `throwIt(short reason)` Deprecated. Deprecated for extended applets and web applications on the Connected Edition of the Java Card 3 Platform. Use constructor instead.
