Java 1.4

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  ( );   }
