public  void access()
Update the accessed time information for this session. This method
should be called by the context when a request comes in for a particular
session, even if the application does not reference it.

 public  void addSessionListener(SessionListener listener)
Add a session event listener to this component.

 public  void endAccess()
End access to the session.

 public  void expire()
Perform the internal processing required to invalidate this session,
without triggering an exception if the session has already expired.

 public String getAuthType()
Return the authentication type used to authenticate our cached
Principal, if any.

 public long getCreationTime()
Return the creation time for this session.

 public String getId()
Return the session identifier for this session.

 public String getIdInternal()
Return the session identifier for this session.

 public String getInfo()
Return descriptive information about this Session implementation and
the corresponding version number, in the format
<description>/<version>.

 public long getLastAccessedTime()
Return the last time the client sent a request associated with this

Return the last client access time without invalidation check

 public Manager getManager()

 public Iterator getNoteNames()
Return an Iterator containing the String names of all notes bindings
that exist for this session.

 public Principal getPrincipal()

Realm.authenticate() calls on every request. If there
is no current associated Principal, return null.

 public HttpSession getSession()
Return the HttpSession for which this object
is the facade.

 public boolean isValid()
Return the isValid flag for this session.

 public  void recycle()

Remove a session event listener from this component.

 public  void setAuthType(String authType)
Set the authentication type used to authenticate our cached

 public  void setId(String id)
Set the session identifier for this session.

 public  void setManager(Manager manager)
Set the Manager within which this Session is valid.

 public  void setMaxInactiveInterval(int interval)
Set the maximum time interval, in seconds, between client requests
before the servlet container will invalidate the session. A negative
time indicates that the session should never time out.

    Object value)
Bind an object to a specified name in the internal notes associated

 public  void setPrincipal(Principal principal)
Set the authenticated Principal that is associated with this Session.

previously authenticated Principal, and avoid potentially expensive
Realm.authenticate() calls on every request.

 public  void setValid(boolean isValid)
Set the isValid flag for this session.
