public interface Key
Key
interface is the base interface for all keys.
A Key
object sets its initialized state to true only when all
the associated Key
object parameters have been set at least
once since the time the initialized state was set to false.
A newly created Key
object sets its initialized state to
false. Invocation of the clearKey()
method sets the
initialized state to false. A key with transient key data sets its
initialized state to false on the associated clear events.
