Constructors Summary

private SessionMessageImpl(String contextName, int eventtype, byte[] session, String sessionID) mEvtType = eventtype; mSession = session; mSessionID = sessionID; mContextName = contextName; uniqueId = sessionID;
public SessionMessageImpl(String contextName, int eventtype, byte[] session, String sessionID, String uniqueID) Creates a session message. Depending on what event type you want this message to represent, you populate the different parameters in the constructor The following rules apply dependent on what event type argument you use: EVT_SESSION_CREATED The parameters: session, sessionID must be set. EVT_SESSION_EXPIRED The parameters: sessionID must be set. EVT_SESSION_ACCESSED The parameters: sessionID must be set. EVT_SESSION_EXPIRED_XXXX The parameters: sessionID must be set. EVT_SESSION_DELTA Send attribute delta (add,update,remove attribute or principal, ...). EVT_ALL_SESSION_DATA Send complete serializes session list EVT_ALL_SESSION_TRANSFERCOMPLETE send that all session state information are transfered after GET_ALL_SESSION received from this sender. param contextName - the name of the context (application param eventtype - one of the 8 event type defined in this class param session - the serialized byte array of the session itself param sessionID - the id that identifies this session param uniqueID - the id that identifies this message this(contextName,eventtype,session,sessionID); uniqueId = uniqueID;

Methods Summary
public java.lang.String	getContextName() return mContextName;
public int	getEventType() returns the event type return one of the event types EVT_XXXX return mEvtType;
public java.lang.String	getEventTypeString() clear text event type name (for logging purpose only) return the event type in a string representating, useful for debugging switch (mEvtType) { case EVT_SESSION_CREATED : return "SESSION-MODIFIED"; case EVT_SESSION_EXPIRED : return "SESSION-EXPIRED"; case EVT_SESSION_ACCESSED : return "SESSION-ACCESSED"; case EVT_GET_ALL_SESSIONS : return "SESSION-GET-ALL"; case EVT_SESSION_DELTA : return "SESSION-DELTA"; case EVT_ALL_SESSION_DATA : return "ALL-SESSION-DATA"; case EVT_ALL_SESSION_TRANSFERCOMPLETE : return "SESSION-STATE-TRANSFERED"; default : return "UNKNOWN-EVENT-TYPE"; }
public byte[]	getSession() return the serialized data for the session return mSession;
public java.lang.String	getSessionID() return the session ID for the session return mSessionID;
public long	getTimestamp() return serializationTimestamp;
public java.lang.String	getUniqueId() return uniqueId;
public void	setTimestamp(long time) set message send time but only the first setting works (one shot) synchronized(this) { if(!timestampSet) { serializationTimestamp=time; timestampSet = true ; } }
public void	setUniqueId(java.lang.String uniqueId) this.uniqueId = uniqueId;
public java.lang.String	toString() return getEventTypeString() + "#" + getContextName() + "#" + getSessionID() ;
