| /** |
| * An externalized view of the underlying {@link SSLSession} used within a |
| * socket/engine. This class provides the caller with a consistent session |
| * handle which will continue to be usable regardless of internal changes |
| * to the connection. It does this by delegating calls to the <b>current</b> |
| * internal session, which is provided by the session {@code Provider} |
| * (i.e. the socket or engine that owns the session). This allows the provider |
| * to switch implementations (for instance, using a JNI implementation to |
| * access live values while the connection is open and a set of final values |
| * when the connection is closed), even if the caller stores a reference to |
| * the session object. |
| * |
| * <p>This class implements the {@link SSLSession} value API itself, rather |
| * than delegating to the provided session, to ensure the caller has a consistent |
| * value map, regardless of which internal session is currently being used by the |
| * socket/engine. This class will never call the value API methods on the |
| * underlying sessions, so they need not be implemented. |
