All Implemented Interfaces:

Serializable

Direct Known Subclasses:

InfinispanSessionData, NoSqlSessionDataStore.NoSqlSessionData

public class SessionData
extends Object
implements Serializable

SessionData The data associated with a session. A Session object has a 1:1 relationship with a SessionData object. The behaviour of sessions is implemented in the Session object (eg calling listeners, keeping timers etc). A Session's associated SessionData is the object which can be persisted, serialized etc.

Method Details

serializeAttributes

public static void serializeAttributes(SessionData data,
 ObjectOutputStream out)
                                throws IOException

Serialize the attribute map of the session. This special handling allows us to record which classloader should be used to load the value of the attribute: either the container classloader (which could be the application loader ie null, or jetty's startjar loader) or the webapp's classloader.

Parameters:

data - the SessionData for which to serialize the attributes

out - the stream to which to serialize

Throws:

IOException

deserializeAttributes

public static void deserializeAttributes(SessionData data,
 ObjectInputStream in)
                                  throws IOException,
ClassNotFoundException

De-serialize the attribute map of a session. When the session was serialized, we will have recorded which classloader should be used to recover the attribute value. The classloader could be the container classloader, or the webapp classloader.

Parameters:

data - the SessionData for which to deserialize the attribute map

in - the serialized stream

Throws:

IOException

ClassNotFoundException
