Class AbstractSessionContext
- SSLSessionContext
A skeletal implementation of
SSLSessionContext
. This class may
be subclassed to add extended functionality to session contexts, such
as by storing sessions in files on disk, or by sharing contexts
across different JVM instances.
In order to securely store sessions, along with private key data,
the abstract methods and
store(char[])
come into play. When storing sessions, a session context implementation
must pass this password to the
Session.prepare(char[])
method,
before either writing the
Serializable
session to the
underlying store, or getting the opaque
Session.privateData()
class from the session, and storing that.
As a simple example, that writes sessions to some object output
stream:
char[] password = ...;
ObjectOutputStream out = ...;
...
for (Session s : this)
{
s.prepare(password);
out.writeObject(s);
}
The reverse must be done when deserializing sessions, by using the
Session.repair(char[])
method, possibly by first calling
Session.setPrivateData(java.io.Serializable)
with the read,
opaque private data type. Thus an example of reading may be:
char[] password = ...;
ObjectInputStream in = ...;
...
while (hasMoreSessions(in))
{
Session s = (Session) in.readObject();
s.repair(password);
addToThisStore(s);
}

getSession
public final SSLSession getSession(byte[] sessionId)
Fetch a saved session by its ID. This method will (possibly)
deserialize and return the SSL session with that ID, or null if
the requested session does not exist, or has expired.
Subclasses implementing this class
must not
perform any blocking operations in this method. If any blocking
behavior is required, it must be done in the
load(char[])
method.
- getSession in interface SSLSessionContext
sessionId
- The ID of the session to get.
- The found session, or null if no such session was found,
or if that session has expired.
implGet
protected abstract Session implGet(byte[] sessionId)
To be implemented by subclasses. Subclasses do not need to check
timeouts in this method.
sessionId
- The session ID.
- The session, or
null
if the requested session
was not found.
load
public abstract void load(char[] password)
throws SessionStoreException
Load this session store from the underlying media, if supported
by the implementation.
password
- The password that protects the sensitive data in
this store.
SessionStoreException
- If reading this store fails, such
as when an I/O exception occurs, or if the password is incorrect.
put
public abstract void put(Session session)
Add a new session to the store. The underlying implementation
will add the session to its store, possibly overwriting any
existing session with the same ID.
Subclasses implementing this class
must not
perform any blocking operations in this method. If any blocking
behavior is required, it must be done in the
store(char[])
method.
session
- The session to add.
remove
public abstract void remove(byte[] sessionId)
Remove a session from this store.
Subclasses implementing this class
must not
perform any blocking operations in this method. If any blocking
behavior is required, it must be done in the
store(char[])
method.
sessionId
- The ID of the session to remove.
store
public abstract void store(char[] password)
throws SessionStoreException
Commit this session store to the underlying media. For session
store implementations that support saving sessions across
invocations of the JVM, this method will save any sessions that
have not expired to some persistent media, so they may be loaded
and used again later.
password
- The password that will protect the sensitive data
in this store.
AbstractSessionContext -- stores SSL sessions, possibly persistently.
