public class SessionEventTrigger
extends InsertableServletImpl
implements atg.naming.NameContextPreBindingListener, NameContextBindingListener

This class fires off SessionEvents for new sessions and expired sessions.

It implements the request pipeline interface so that whenever a new session is created for a request, a SessionEvent can be fired.

Additionally it implements the NameContextBindingListener interface so it can listen to the SessionManager as it unbinds session objects (i.e. expires sessions) and thus fire a SessionEvent.

Why doesn't it also listen for the binding of session objects instead of sitting in the pipeline? If that was done, we could not get a handle to the request object or the profile object to pass along with the SessionEvent.

At this point you should note that SessionEvents for session expiration do not contain the request object.

This class must be inserted into the request pipeline (probably best to insert it after DynamoServlet) in order for it to watch for new sessions.

This class must be added to the SessionManager's list of nameContextBindingListeners in order for it to know when sessions are destroyed.

Field Detail

CLASS_VERSION

public static java.lang.String CLASS_VERSION

Class version string

Constructor Detail

SessionEventTrigger

public SessionEventTrigger()

Empty constructor.

Method Detail

setDistributor

public void setDistributor(atg.service.event.EventDistributor pValue)

The EventDistributor to send fired events to.

getDistributor

public atg.service.event.EventDistributor getDistributor()

The EventDistributor to send fired events to.

setSessionManagerPath

public void setSessionManagerPath(java.lang.String pValue)

The component name and path for the SessionManager. Note that we must use the name and path instead of passing an actual reference to the manager to prevent a startup loop since this event trigger sits in the pipeline.

getSessionManagerPath

public java.lang.String getSessionManagerPath()

The component name and path for the SessionManager. Note that we must use the name and path instead of passing an actual reference to the manager to prevent a startup loop since this event trigger sits in the pipeline.

setProfilePath

public void setProfilePath(java.lang.String pValue)

The full name of the Profile component for every request.

getProfilePath

public java.lang.String getProfilePath()

The full name of the Profile component for every request.

getNumNewSessionEvents

public long getNumNewSessionEvents()

Returns property NumNewSessionEvents
