Lofi Dewanto version:    1.0 Field Summary protected  HttpPresentationComms myComms      Saved HTML input and output context. Method Summary abstract protected  void checkForAccessList()      This method should be implemented in the subclass to change the behaviour of the access list. public  StandardApplication getApplication()      Returns the application object associated with the current request. public  HttpPresentationComms getComms()      public  String getPageContentForEvent(String event)      If an event parameter is defined then this invokes the method that handles that event. abstract public  String handleDefault()      This is the procedure that is called if there is no "event" HTTP parameter found. public  void handleEvent(HttpPresentationComms comms)      abstract protected  boolean isForPublicAccess()      This method should be implemented in the subclass, so that it returns true if this particular request requires the user to apply first for the access. abstract protected  boolean loggedInUserRequired()      This method should be implemented in the subclass so that it returns true if this particular request requires the user to be logged in, otherwise false. public static  void writeDebugMsg(String msg)      Field Detail myComms protected HttpPresentationComms myComms(Code) Saved HTML input and output context. Method Detail checkForAccessList abstract protected void checkForAccessList() throws ClientPageRedirectException, BasePOException(Code) This method should be implemented in the subclass to change the behaviour of the access list. Access list contents the current student and the current enrollment. If the the current enrollment is not for a public access, the student has to have an access list (accepted) to get into this enrollment. getApplication public StandardApplication getApplication()(Code) Returns the application object associated with the current request. the ebroker application object. getComms public HttpPresentationComms getComms()(Code) The saved comms objectsto whichever subclass needs it getPageContentForEvent public String getPageContentForEvent(String event) throws Exception(Code) If an event parameter is defined then this invokes the method that handles that event. handleDefault abstract public String handleDefault() throws HttpPresentationException(Code) This is the procedure that is called if there is no "event" HTTP parameter found. It must be overriden by the subclass to do default processing or error checking/handling. String The String representation of the HTML or (other format)of the document to be displayed. This method would need to be changedif you wanted to return binary data as well. It returns a Stringfor simplicity right now. handleEvent public void handleEvent(HttpPresentationComms comms) throws Exception(Code) Method to call the proper method for the incoming event isForPublicAccess abstract protected boolean isForPublicAccess() throws BasePOException(Code) This method should be implemented in the subclass, so that it returns true if this particular request requires the user to apply first for the access. For public means everybody can access this, otherwise he or she needs to be activated first. loggedInUserRequired abstract protected boolean loggedInUserRequired()(Code) This method should be implemented in the subclass so that it returns true if this particular request requires the user to be logged in, otherwise false. writeDebugMsg public static void writeDebugMsg(String msg)(Code) Method to write a debugging message to the debug log channel when the DEBUG flag is turned on Parameters:   msg - The message to write to the DEBUG log channel Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
