| Destroyable | javax.security.auth |
Classes that encapsulate sensitive
information, such as security
credentials, may implement this
interface to provide an API that allows the sensitive information to
be destroyed or erased. The destroy(
)
method erases or clears the sensitive information. It may throw a
DestroyFailedException if the information cannot
be erased for any reason. It may also throw a
SecurityException if the caller does not have
whatever permissions are required. Once destroy( )
has been called on an object, the isDestroyed(
) method returns
true. Once an object has been destroyed, any other
methods it defines may throw an
IllegalStateException. public interface Destroyable {
// Public Instance Methods
void destroy ( ) throws DestroyFailedException;
boolean isDestroyed ( );
}
