org.mortbay.jetty.servlet
Class AbstractSessionManager

java.lang.Object
  org.mortbay.component.AbstractLifeCycle
      org.mortbay.jetty.servlet.AbstractSessionManager

All Implemented Interfaces:: Serializable, LifeCycle, SessionManager

Direct Known Subclasses:: HashSessionManager

public abstract class AbstractSessionManager
extends AbstractLifeCycle
implements SessionManager
extends AbstractLifeCycle
implements SessionManager

An Abstract implementation of SessionManager. The partial implementation of SessionManager interface provides the majority of the handling required to implement a SessionManager. Concrete implementations of SessionManager based on AbstractSessionManager need only implement the newSession method to return a specialized version of the Session inner class that provides an attribute Map.

If the property org.mortbay.jetty.servlet.AbstractSessionManager.23Notifications is set to true, the 2.3 servlet spec notification style will be used.
