Method Detail

processUpdate

public boolean processUpdate(int state)
                      throws EclipseException

This method is called when a running knowledge base is about to (re)load an application from a configuration file. Since working memories must be deleted before a load occurs, this listener gives user's application a chance to terminate running working memories and to save data stored in working memories, if needed. If the user wants to prevent automatic update of the configuration, they should return false.

Parameters:

state - An int with the value of either kbisWaitingToLoadWithoutClearing, kbisWaitingToClearAndLoad, or kbisPostLoad .

Returns:

true if it is OK to reload the application.

Throws:

EclipseException - if there is an error
